Steel truss structure and space frame structure are common architectural structure forms, the same points of both are connected by building materials, what is the difference between the two?When are trusses used?When to use the space frame? 1. Common form of structure The common shapes of the space frame are triangular cone, triangular body, cube, truncated quadrangle, etc. Generally, it has bolt ball node, welded ball node, etc., which is a kind of spatial structure. Generally, trusses include single-row trusses, triangular trusses and quadrilateral trusses. The trusses we often say are quadrilateral trusses and are also the most commonly used kinds of trusses, such as steel structure trusses and aluminum alloy trusses. 2. Structural stress The space frame structure can be supported around, multi-point support, large stiffness in the surface, belongs to the bidirectional stress system. The truss structure is a kind of plane structure, which needs the support of externa

The construction method of large space frame structure is constantly innovated.With the increasing diversity and span of space structure, the construction method of space frame  structure needs to be innovated, and the construction technology has also been developed.Construction technology is very important in the construction of large space structure. Only reasonable construction scheme and scientific analysis can guarantee the safety and economy of the structure. Theoretical research on spatial structure has been further developed.With the continuous innovation of space structure system and form, the theory of space structure will inevitably develop in depth and breadth.Earlier studies had more focus on static under the action of shape and structure analysis method, and the simplified method such as quasi plate method, the finite difference method study, after gradually from static to dynamic, from linear to nonlinear, on the spatial structure of the static and dynamic stabilit

The structure of the space frame is triangular cone, cube, etc. The overall weight of the space frame is relatively light, and the seismic performance is also very good. What is the quality standard of the space frame during the processing of the grid? 1、When the space frame is processed, it shall have the material proof, the load-bearing tensile report of various specifications of the space frame, and the material proof of steel. 2、the space frame processing, welding materials and coating materials should also be certified, as well as the sleeve, cone head material report, the use of steel to test the weldability of steel. 3、Movable supports for the space frame shall also be qualified, and the inspection and acceptance records of weld bends shall also be provided for acceptance materials such as the overall size of the network frame after installation.

Steel structures In the September 1985 earthquake in Mexico (magnitude 8.1), there were 102 steel structures in the high intensity area of   Mexico City, of which 59 were built after 1957, and steel buildings built after 1957 collapsed Or the damage is not serious. Compared with the reinforced concrete structure, the steel structure is lighter. Why is the steel structure of the steel structure light earthquake damage? The following editors from China Research and Construction Jianbian take you to decipher the secret of steel structure seismic design in the steel structure. The seismic design of general steel structures can be briefly described as follows: 1. Perform dynamic analysis to obtain the necessary lateral force. Before the calculation, there must be the most basic structural elements, especially the structure's own weight and lateral force transmission system must have a clear plan. The simplest dynamic analysis is the bottom shear method. This is calculated by
