Influence of space frame fabrication, installation method and span size on space frame structure selection

Image
The space frame structure is affected by many factors, such as space frame production, installation method, span size, steel index, etc., which all affect the determination of which space frame form to use to a certain extent. 1. For example, the joints are welded, and the space frame composed of plane trusses is more convenient to make than the space frame composed of quadrangular pyramids; the two-way orthogonal space frame is more convenient than the two-way oblique space frame and the three-way space frame. The frame is convenient; the quadrangular pyramid space frame is more convenient than the triangular pyramid space frame. 2. If the installation method does not adopt the overall lifting or hoisting, but adopts the strip or block installation, or adopts the high-altitude sliding method, select the two-way orthogonal positive space frame, the positive square pyramid space frame, and the positive evacuated square pyramid space. The three orthogonal space frames such as the frame

Three types of steel structures commonly used in gas stations

Gas stations are common to everyone. The main material of gas stations is steel structure, and the space frame structure is a high-order statically indeterminate structural system. It has the advantages of small space force, light weight, high stiffness, and good seismic performance. The space frame is a manifestation of the space frame. The SAFS steel structure shares 3 forms of the space frame of the gas station below: 1. The space frame of the triangular pyramid system: it is divided into the triangular cone space frame, the evacuated triangular cone space frame, the honeycomb-shaped triangular cone space frame, etc. It is suitable for buildings with flat shapes such as rectangles, triangles, polygons and circles. 2. Space frame of hexagonal pyramid system: The space frame structure composed of heptahedrons is called the space frame of hexagonal pyramid system. Its basic unit is 6 chords, a hexagonal pyramid gas station space frame formed by 6 chords. 3. Space frame of cross truss
