Study on Seismic Properties of Assembled Monolithic Metro Station Based on Response Deformation Method

摘要

Assembled monolithic metro station is a potential kind of structure technique to solve a series of problems caused by the cast-in-situ concrete technique used in the traditional construction way of metro station. Seismic properties of this underground structure are modeled and studied based on the response deformation method, different mechanical properties of assembling joints and different strata conditions are considered. Results indicate that its seismic properties possess great sensibility to the mechanical properties of assembling joints, with pillar to be the most sensitive. Thus sufficient attention should be paid to seismic design and construction quality of the assembling joints.
