摘要
本文对六层异形柱框架和普通框架各一榀进行了抗震推倒分析。研究了结构的层间位移和屈服机制,并对其抗震能力进行了分析。在上述研究的基础上,结合异形柱框架结构推倒分析的结果。
The article make push-over analysis for one common frame and one abnormity columnination frame.Push-over analysis on specially shaped column frames arrived at displacement between stories,yielding mode and evaluate aseismic capacity.Based on above researches,combining the special-shaped columns frame push-over results the article analysis the effect of the axial compression ratio and the steel ratio to the results.The article provide some practical suggestion on the design of the specially-shaped column frame.
