Analysis of Key Design Points for the Fully Frame-Supported Shear Wall Structural System of the Subway Upper Cover Project
In this study,the force characteristics,seismic performance and reliability of fully frame-supported shear wall structural system of metro superstructure were analyzed in combination with engineering examples.The elastic analysis and elastoplastic analysis of the structure were carried out by multiple commonly used finite element calculation software,and the specialized finite element analysis of the key thick-plate transfer structure was performed.The analysis shows that the structural system can transmit force through the conversion of components effectively,and meet the requirements of seismic performance under different earthquake levels.It can avoid the vertical components of the upper tower falling to the ground,maximize the use of the cover plate,improve the development degree of the cover property,and more efficiently utilize the land resources in the urban center.This study can provide some reference and inspiration for the development of similar subway upper cover projects in the future.
