The Modal Analysis of a Multilayer Concave-Convex Irregular Reinforced Concrete Frame Structures before and after Seismic Isolation

Abstract:

It used lead core type laminated rubber pad as a base isolation device. Using the ANSYS software, it analyzed the modality of a multilayer concave-convex irregular reinforced concrete frame structures before and after seismic isolation. Comparison of the cycle, frequency and modal participation mass coefficient of the multilayer concave-convex irregular reinforced concrete frame structure before and after isolation in Kobe wave. It concluded that the lead laminated rubber bearings for multilayer concave-convex irregular reinforced concrete frame structures have seismic isolation effect.
