Metal Buildings Specification

The metal buildings uses steel to form a load-bearing structure. Generally, beams, columns, trusses, and other components made of section steel and steel plates constitute a load-bearing structure, which together with roof, wall, and floor, form a building.

Compared with traditional concrete buildings, metal structure buildings use steel plates or section steel instead of reinforced concrete, higher strength, and better seismic resistance. And because the components can be manufactured in factories and installed on-site, the construction period is greatly reduced. Due to the reusability of steel, it can greatly reduce construction waste and become more environmentally friendly. Therefore, it is widely used in industrial buildings and civil buildings all over the world.

Advantage
1. Greatly save construction time. Construction is not affected by the season
2. Increase the use area of buildings, reduce construction waste and environmental pollution
3. Building materials can be reused, stimulating the development of other new building materials industries
4. Good seismic performance, easy to transform, flexible and convenient in use, bringing comfort and so on
5. High strength, lightweight, high safety and wealth of components, and lower building cost

Disadvantages:
1. Heat-resistant and non-fire-resistant, fire-resistant coatings are required
2. It is susceptible to corrosion, and the surface needs to be coated with anti-corrosion coatings to reduce or avoid corrosion and increase durability

A steel truss structure is one in which rods are hingedly connected at both ends. The truss comprises straight rods and generally has a planar or spatial structure with triangular units. The truss rods mainly bear axial tension or pressure so that the strength of the material can be fully utilized. When the span is large, it can save material compared with solid web beams, reduce self-weight, and Increase stiffness.

Steel Truss Structure

Definition of truss structure:

A truss is a support beam structure composed of rods connected by welding, riveting, or bolting.

Why Choose Steel Truss Structure:

The steel truss rods mainly bear tension or pressure, which fully exploits the role of materials, saves materials, and reduces the structure’s weight. Commonly used ones include steel trusses, reinforced concrete trusses, prestressed concrete trusses, wood trusses, steel and wood composite trusses, and steel and concrete composite trusses.

The steel truss rods mainly bear tension or pressure, which fully exploits the role of materials, saves materials, and reduces the structure’s weight. The truss structure is developed based on the grid structure. Compared with the grid structure, it has unique advantages and practicability, and the steel used is also more economical.

The advantages of steel truss:

  1. The design, production, and installation of steel trusses are simple;
  2. The truss has many adaptable spans and extensive applications.

Layout method of steel truss design

  1. The form of the trusses should be based on the requirements of the building, taking into account factors such as roof materials, skylights, purlins, support arrangements, whether the roof trusses and columns are hinged or rigidly connected, and finally, determine the overall dimensions and web rod system.
  2. The web member system of the truss. The structural stress should be reasonable, and the node structure should be simple and unified. The number of web members is small, and the total length is short. It is advisable to make the lengthy web members under tension and the short web members under compression so that the chord members do not produce a local bending moment. The angle between the oblique web rod and the chord rod should be 35 to 55 degrees.
  3. Standard web bar systems include herringbone, ascending, and subdivided systems, which reduce the internodal length of the upper chord and increase the height. The herringbone type is the most widely used in roof trusses. The subdivided truss system saves more steel than the structural solution of dense main web rods.
  4. The setting of truss joints should be based on architectural or technological requirements, equipment hanging, etc., so the load acts on the nodes as much as possible.
  5. For trusses with larger spans, arching can solve the problem when the deformation deflection exceeds the limit.
  6. If the span is too large, it must be divided into sections for transportation. A truss with a span less than or equal to 12 m does not need to be segmented; when the span is greater than 12 m but less than 20 m, it can be divided into two segments; when it is greater than or equal to 20 m, it can be divided into multiple segments, but the length of each segment should not exceed 12m; splicing joints, It should be located at 1/3 of the span of the corridor.

Commonly used cross-sectional forms of steel trusses

When the stress is minor, a double-angle steel section is used. When the component adopts a double-angle steel section and is large (challenging to purchase when ≥160mm), rolled T-shaped steel should be used instead of double-angle steel as the upper and lower chords of the truss. When the load is relatively large, H-shaped steel should be used.

steel truss section

T-shaped and double-angle steel are generally used in industrial buildings, while H-shaped steel is generally used for civil use. H-shaped steel is more convenient to connect to secondary beams. Civil use is usually made of concrete slabs, and the load is generally more significant than that of industrial use.

Application areas of steel truss structures

1. Industrial buildings:


For industrial buildings with large spans, using steel structure trusses can reduce the steel used, meet the requirements of large spans without central columns, and provide a broad space for production and warehousing logistics.

2. Commercial buildings:


Large spaces, broad views, and flexible layouts are usually required in commercial buildings, such as shopping malls, office buildings, hotels, etc. The lightweight design of steel structure trusses allows the building to be more flexible in space planning. At the same time, the truss structure can support large spans, providing a more expansive space for commercial buildings.

3. Sports venues:


Sports venues are another area suitable for steel structure trusses. Large sports venues require adequate space coverage to ensure safety and visibility from spectator seats. Steel structure trusses can easily support large roofs, providing a vast space for sports venues. At the same time, their strength and stability also meet the requirements of large-span design, providing an ideal venue for hosting various sports events.

4. Bridge engineering:


In bridge engineering, steel structure trusses also demonstrate excellent performance. Steel structure truss bridges have the advantages of being lightweight, having high stiffness, and having a short construction period. They are especially suitable for crossing large rivers or deep valleys. Their lightweight design reduces the bridge’s weight while ensuring sufficient strength, providing reliable structural support for the bridge project.

steel box column

There are 154 main trusses in total. The single truss is 24 meters long and 3.5 meters high. The maximum ceiling height is about 14.1 meters, and the weight is about 12 tons. The main truss chords and web members are all H-shaped steel.

Main Truss Structure

There are 522 sub-trusses in total. The single truss is 24 meters long, 4 meters high, has a maximum ceiling height of 14.1 meters, and weighs about 7.5 tons. The chord and web members of the secondary truss are H-shaped steel.

Sub-truss structure

The installation plan of the Steel Truss Structure:

The steel structure building consists of two welding and stamping workshops divided into three zones: A, B, and C. Three areas can be constructed at the same time, saving construction time.

Construction sequence of Steel Truss Structure in A and B area:

The main process flow of site hoisting construction: steel column → main truss → secondary truss → roof bracing, purlin.

Construction sequence of the steel truss structure in Zone C:

The process of on-site hoisting: hoist steel column → install column bracing → hoist crane beam and correction → roof beam → installation of roof bracing and purlins.

The steel structure in Zone A and B is divided into two construction lines, starting from 1 axis and 15 axes. 4 sets of 25-ton trucks hoist the steel columns, and four sets of 45-ton trucks hoist the main roof truss due to their heavyweight. Four sets of 30-ton truck cranes hoist the roof sub-truss, and the trusses are assembled on-site. The roof trusses are constructed on-site with four sets of 10-ton truck cranes. After the trusses are assembled on the ground, they are directly hoisted in place by 45-ton and 30-ton truck cranes.

Workshop Layout Plan

Analysis and selection of hoisting machinery in Steel Workshop A and B:

The maximum length of the steel column is about 16 meters, and the maximum weight is about 8.2 tons. A 25-ton truck crane is selected with a boom length of 24.2 meters, a hoisting radius of 8 meters, a height of 21 meters, and a lifting weight of 8.45 tons, which fully meets the lifting requirements.
