In the seismic response analysis of piping systems, finite element analysis is performed with analysis method guidelines [1]–[4] established based on benchmark analysis. However, since it takes a great deal of effort to carry out finite element analysis, a simplified method to analyze the seismic response of complex piping systems is required. In this research, we propose a method to reduce an equivalent spring-mass system model with low degrees of freedom, which can take into account the main mode of the complicated piping system. Simplified seismic evaluation is carried out using this spring mass system model with low degrees of freedom, and the accuracy of response evaluation is confirmed by comparison with finite element analysis.

By testing 4 pin standard frame-supported multi-ribbed composite slab’s mechanical proper- ties under the horizontal load’s funtion,it is got that the earthquake resistance performance influence of lateral stiffness satio to frame-supported multi- ribbed slabs.The reasonable value scope of stiffness satio between transformation layers is obtained by finite element analysis of seismic response of frame-support- ed multi-ribbed slab structures and provides theoretical basis to engineering design
