Influence of Stiffness of the Column Base on Anti-Seismic Performance Whithin the Additional Steel Layer of the Firsthigh-rise Steel Structure In Shanxi Province

摘要

The first high-rise steel structure of Shanxi Province is adding storeys based on the already built concrete structure with the steel frame-a support structure system. This article has set models respectiely on the rigid zocle and semirigid zocle for aimed at how to deal these two kinds of different materials interface which are steel structure and concret structure. The Midas Gen is employed to analyze the. anti-seismic structural behaviors with rigid or hinge column base influence. Could be a reference to the similar storey-adding projects.
