For steel structure buildings, although the seismic characteristics of the steel structure itself are good, the steel structure cannot protect the electromechanical system installed in the building
In the construction of commonly used steel structures, the design and configuration of building electromechanical anti-seismic supports and hangers are based on the relative standards in the Code for Seismic Design of Building Electromechanical Engineering and the cases in the project. There are many construction methods
As for the grid structure in the steel structure, sometimes the pipeline will be installed under the grid, which is very far away from the purlin, and the size of the suspender is very long
