底层大空间剪力墙结构中框支柱弹塑性稳定性试验研究及理论分析

Stability investigation and theory analysis for frame columns in shear wall structures with large space ground floor

通过对三榀“π”型试件的试验研究，确认ＲＣ底层大空间剪力培结构中，框支柱在满足设计规范要求的情况下，仍存在失稳破坏的可能性，并提出了弹塑性稳定性分析方法。

Through the investigation of three frame specimens with "π"pattern,this paper proves that the instable passibility of the frame column supporting wall would exist on condition that the design code requirements are satisfied, and presents a method used to analyze the elastoplastic stability.
