The Introduction of the Truss Steel Structure

The Definition of a Truss

A truss refers to a truss beam, which is a latticed beam-type structure, that is, a structure in which rods are connected by hinges at both ends. The truss comprises straight rods and generally has a plane or space structure with triangular elements. The truss rods mainly bear the axial tension or pressure, so the material's strength can be fully utilized. When the span is large, it can save material, reduce the self-weight and Increase stiffness. Trusses are also commonly referred to as roof trusses as they are primarily used in roof structures of buildings.

The Advantage of a Truss

The advantage of the truss is that the rods are mainly subjected to tension or pressure so that the strength of the material can be fully utilized. When the span is large, it can save material, reduce its weight and increase the stiffness compared with an H-shape beam. According to the structure, trusses can be divided into triangular truss, trapezoidal truss, polygonal truss, hollow truss, and truss bridge. According to the product type, it can be divided into the fixed truss, Folding truss, butterfly truss, and ball joint truss.

Theoretical Principle

A truss is a geometrically invariant structure composed of triangular frames composed of straight rods. The joints between members are called nodes. According to the axis of the truss members and the distribution of the external force, the truss can be divided into a plane truss and a space truss. Spatial structures such as roof trusses or bridges are composed of a series of parallel plane trusses. If they mainly bear plane loads, they can be simplified as plane trusses to calculate.

The Application 

Truss structures are often used in large-span steel structure factories, exhibitions, gyms, bridges, etc. Truss steel structures are widely used in steel structures, such as roofs (roof trusses, etc.) and crane beams (crane trusses) of industrial and civil buildings, bridges, cranes (its towers, beams or booms, etc.), hydraulic gates, In offshore oil production platforms, steel trusses are often used as the main components of load-bearing structures. Various types of steel grids, which are widely used in the roof structure of large-span public buildings, belong to space steel trusses. Various types of towers, such as TV, power transmission, drilling, crane towers, and mast towers, commonly used three-sided, four-sided or multi-sided flat trusses composed of space steel trusses.

1000m2 Truss Steel Structure Project Project

Compared with truss beams and solid web beams (that is, beams we generally see), in terms of bending resistance, due to the concentrated arrangement of the tension and compression sections at the upper and lower ends, the internal force arm is increased, so that with the same amount of material, Greater flexural strength is achieved. In terms of shear resistance, the shear force can be reasonably transmitted to the support by arranging the web rods reasonably. In this way, whether it is bending or shearing, the truss structure can give full play to the strength of the material, so it is suitable for building roof structures of various spans. More importantly, it converts the complex stress state inside the solid web beam under the action of transverse bending into the simple tension and compression stress state in the truss member, which enables us to intuitively understand the distribution and transmission of force, and facilitate the change and combination of the structure.

Dorian team designed and exported a 1000m2 steel warehouse to Thailand, which adopt a truss steel structure. Steel beams and columns are made up of square tubes and displayed by a triangle pattern, which keeps the whole steel structure stable and strong. Moreover, All steel beams and columns are plane trusses and single slope beams as it’s lightweight and thus saved much material cost.

    Why Structural Steel is the Best Construction Material

    When it comes to the vast array of construction materials available, structural steel is often considered to be the best. In the production of structural steel, high-quality steel grades are employed, and the finished product is available in a wide range of cross-sectional shapes. Steel structural construction is the most flexible building material available due to its great strength, long life, and ease of installation. Construction of large multi story structures (such as skyscrapers), industrial buildings (such as factories), bridges, and tunnels are just a few examples of the many applications for structural steel.

    There are a variety of reasons why structural steel is the best construction material. Here are just a handful of the many reasons behind this:

    It’s relatively cheap

    During the course of the construction process, steel construction produces comparatively little waste. Furthermore, steel structures are low-maintenance and long-lasting, which lowers the total cost of the project while simultaneously increasing the return on the resources that were invested in its design and implementation.

    A significant amount of structural steel is used in many construction projects. Concrete framing systems are much more expensive to construct than structural steel framing systems, which also incorporate fire protection and decking as standard features.

    It’s strong

    The use of structural steel over other building materials is preferred because it has superior compression and tension properties, resulting in a lighter overall structure. Despite its light weight, structural steel offers a considerably stronger strength-to-weight ratio than any other building material available to the construction industry today. Because of the excellent strength-to-weight ratio of structural steel, buildings constructed with this material are both lighter and stronger. Neither structural steel nor concrete changes form or shrinks.

    It’s fast to build with

    It takes little time and effort to put up a steel frame construction. Precision and predictability of steel components allow for a reduction in overall construction time. When selecting structural steel for construction, it is critical to consider the speed with which it can be erected. Short construction periods may be favourable in terms of both time and money.

    It’s adaptable

    Building using structural steel has always been a favoured material among architects, designers, and engineers. Because of steel's adaptability, engineers, architects, and designers are able to build the most intricate designs possible. Steel is the only building material in the construction business that is capable of fostering innovation, creativity, and the freedom to express oneself.

    It looks good

    The use of structural steel allows for the creation of large, column-free interiors, which gives the building a sense of spaciousness. Given the malleability of structural steel, architects and designers may experiment with new ideas and develop different textures and shapes that distinguish their work from other similar structures.

    Because of these and several other benefits, structural steel is the greatest construction material available. Steel structural designs are often employed by engineers to construct designs that would be impossible to construct with any other material. If you are convinced of the benefits of structural steel, you should include it into your projects. In addition, always use structural steel fabricators that are professionals in their area of work.

    Optimal aspects of Steel Structure Buildings and Warehouses 3

    Optimal aspects of Steel Structure Buildings and Warehouses

    Steel, concrete, and timber are all commonly used materials in constructing structures, and they can each be argued to be suitable for certain types of projects. In a steel-structured building system, steel columns and beams are utilized to construct structural components like floors, roofs, cladding, interior fixtures, and occupants. Consequently, steel frames are the most common choice for modern buildings and warehouses because they have many advantages over other materials. In this article, we will try to look into why steel structure buildings are so popular nowadays.

    Optimal aspects of Steel Structure Buildings and Warehouses

    Design Freedom, Strength, and Beauty

    Steel Structure buildings are more attractive and unique to look at. Steel allows architects to design more freely concerning color, texture, and shape. Thanks to its strength, durability, beauty, precision, and malleability, it provides architects with options for creating innovative solutions. That is one of the most significant advantages of steel structure construction. With steel's long-spanning capability, large open spaces can be made without intermediary columns or load-bearing walls.

     

    Availability and Accessibility

    Modern buildings nowadays undergo radical, rapid changes in their function. It is not uncommon for tenants to request changes that significantly increase floor loads. A new layout might require repositioning walls to accommodate unique needs and space requirements. Structures made of steel can accommodate such adjustments. It is possible to build non-composite steel beams by fusing them to the existing subfloor. It helps steel structure building to provide the desired shape and style.

    Fast and Easy to Build

    In any season, steel can be erected quickly and efficiently. With very little on-site labor, components are pre-manufactured off-site. Depending on the scale of the project, a complete frame can be erected in days rather than weeks, reducing construction time by 20% to 40%. Due to its low-point contact with the earth, steel is often a good choice for single dwellings on more challenging sites. This is why you can build steel structure buildings for warehouse art anytime.

    Resistance to Earthquakes

    There is no way to predict earthquakes' magnitude, frequency, duration, or location. Due to its inherent flexibility and ductility, steel is an excellent material for design. Instead of crushing or crumbling under harsh conditions, steel flexes. The primary purpose of a steel structure building's beam-to-column connections is to support gravity loads. Nevertheless, wind and earthquakes can cause considerable lateral loads to be applied.

    Improves Fire Resistance

    A thorough understanding of how steel buildings respond to fire has been gained through extensive tests of structural steelwork and complete steel structures. Steel-framed buildings can be precisely specified regarding fire protection requirements by advanced design and analysis techniques, often resulting in significant savings on the amount of fire protection required.

    Final Words

    There are different types of steel structures that are popular. In an era where property prices skyrocket, steel can save money by reducing the need for load-bearing posts in housing. It is easy to build steel structure buildings regardless of the weather, and they also have many positive aspects.

    Dorian Accomplish 3600 Square Meter Two-story Steel Workshop Project in Colon City, Germany

    Project information

    Project information: 3 sets 40X30X14M two-story pharmaceutical steel structure workshop with PU sandwich panel wall + glass wool roof

    Project location: Colon city, Germany

    Consultation before the cooperation

    Dorian made the design as the usual after received the inquiry from the client, and the design drawing only spent 3 hours to be finished, and sent it and detailed price list to the client. The client was amazed at Dorian’s efficiency. But, due to the demand of a lot of precision instruments and equipment in the workshop, the client has high requirements of fireproof function for the steel structure and panels. On the other hand, winter in Europe is such cold, therefore,Dorian suggested that paint fireproof coating on the surface of steel structure and use PU sandwich panel as the roof panel and wall panel, which can greatly improve the fireproof level and thermal insulation function as well as anti-corrosion.

    The client was pleased with Dorian’s suggestion, but they refused the price because of some force majeure such as continuously rising freight rates and unpredictable shipping schedules ,and other reasons. Dorian has to modified the design and recommended glass wool sandwich panel instead of the PU panel, which is also with good insulation function and more economical price. In additions, the glass wool has smaller volume, which can save the container space when loading, and finally save shipping cost. After a tough but pleasant negotiation, the client accepted Dorian’s solution and price eventually.

    A visit prior to the formal cooperation

    Considering that it was the first cooperation, before paying the deposit, the client asked their colleagues in Shenzhen office to visit Dorian’s factory. After a long journey, Dorian team picked up the clients at the high-speed railway station and had a pleasant meeting with them. The customer have a site work of the production plant and have a detailed consultation with the engineers and designers during the visit. After that, the client recognize the Dorian's strength and service, was more tend to cooperate with Dorian’s team and Dorian’s factory.

    Installation

    Dorian also can provide installation service based on the demand of the client, but because of the covid-19, the client has to give up the service which invite Dorian’s installation team to their city to help them install the steel structure workshop. Dorian reassured the client quickly, and in order to guarantee the smooth installation of this engineering, made detailed installation manual and installation video in time before they received the cargoes. Meanwhile, Dorian also provided professional on-line service to the client to solve any problems that arise during the installation process. now the steel structure workshop has been successfully installed under Dorian’s help, the workers are decorating and installing the equipment.
