多层异形柱框架结构的抗震分析

Aseismatic Analysis of Multiple Storied Frame Structure with Special Typed Columns

框架结构具有较好的抗震性能、灵活的使用空间，但其柱截面较大，墙面凸处，影响使用．针对多层建筑的结构计算采用工程设计中常用的振型分解法和动力时程法，研究多层建筑中异形柱框架结构的动力特性，并对结构进行抗震分析．结果表明，异形柱框架结构的抗震性能完全可以满足规范的要求．

The frame structure excels in its aseismatic performance and flexible usable space;but its utilization is affected by fairly large section of columns and prominances on the wall.By adopting the methods of vibrating decomposition and dynamic time distance commonly used in engineering design,the author makes a study on the dynamic property of multiple storied frame structure with special shaped columns; and carries on an aseismatic analysis. As shown by the study, the aseismatic performance of frame structure with special shaped columns will completely fulfil standard requirements.
