Finite Element Modeling and Seismic Response Analysis of Pile Slab Structure
Pile slab subgrade is a new type of subgrade structure proposed in recent years. Compared with soil subgrade, it has the advantages of small settlement, large overall stiffness and high smoothness. In this paper, a three-dimensional finite element model of pile slab subgrade is established by using SAP2000, which is a large-scale finite element analysis software. Three E1 seismic waves and three E2 seismic waves are respectively generated according to the horizontal design response spectra of E1 and E2 horizontal earthquakes by the way of artificial generation of time history waves. The seismic responses of three waves under the action of E1 and E2 earthquakes are compared. Through XTRACR analysis software, the ability of key section of pier is analyzed. Comparing the variation of the bending resistance of the section of the pile-slab subgrade structure with prestressed steel bars and non-prestressed steel bars, some useful conclusions are obtained.
