Seismic Response Analysis of Medium Pressure Vertical Multilayer Pipe Support System in High-rise Building

摘要

Based on finite element analysis software ANSYS, using shell elements and space beam elements, finite element model of the vertical multilayer pipe support system of high-rise building is created. The dynamic characteristics and seismic response of piping system are analyzed under earthquake load using multi-point earthquake response spectrum analysis, and the strength and stiffness of components of plate and shell are assessed based on the corresponding seismic code. With the superposition calculation of spectrum analysis and static analysis, the results indicate that the strength and stiffness of fixing trestles and pipes satisfy the requirements in the design of the earthquake.
