华 华 中 科 技 大 学 硕 士 学 位 论 文 II II Abstract With rapid development in technology, architecture has become increasingly diversified. Complex architectural styles continue to emerge today, it has provided a new development opportunity for structure design, and also posed many severe challenges. In today’s project design, more and more irregular structures have been adopted, a kind of special column which based on beam has been used very frequently. As stiffness of the floor including these special columns varies from adjacent floors, it will affect the dynamic properties of the whole structure. For safety purposes, in-depth study of how the special column will influence dynamic properties of the system is very necessary. This paper starts from studying story stiffness, then, it analyzes vibration modes, cycles and lateral stiffness ratio of stories of this special frame system, which including special columns. After that, it adopts a finite element analysis and design software SATWE to calculate and analyze this special frame system. SATWE could provide the maximum story displacement, maximum story drift angle and their variation curve under lateral earthquake condition. In this paper, elastoplastic dynamic analysis software EPDA has been used to find the weak story of this frame system, and also to make sure the load-bearing capacity. Through these analysis, it has concluded the deformation characteristics of the special frame system which includes columns based on beams, and put forward several suggestion for arranging this special columns, all of these could provide references for engineering design.
