Pushover Analysis of the Concrete Cassette Structure of Multi-story Long-span Industrial Buildings

摘要

Pushover analysis, a computing method that combines nonlinear procedure with response spectrum and graph method, is an important technique for performance-based seismic design. In this paper, the fundamental principles and method of pushover analysis are introduced and then SAP2000 is used to execute the pushover analysis and performance evaluation of the concrete cassette structure. This kind of structural system possesses three-dimensional mechanical properties. It offers spacious rooms due to the long span of concrete vierendeel grid slab floor and the absence of beams and columns within. And it is characterized for its easy construction, aesthetic appearance, and vertical space economy.
