Analysis of Influence Parameters to Dynamic Stability and Ultimate Displacement of Single-story Frame
【摘要】 采用有限元法对多种单层钢框架结构进行动力稳定性分析,研究不同地震作用、长细比、轴压比等参数对动力稳定性的影响,绘制出轴压比与动力极限位移的关系曲线,提出单层钢框架在实际工程中防倒塌设计的建议。
【Abstract】 Dynamic stability analysis of many single-story frames is analyzed based upon the finite element method,the influence of different earthquake motion,slenderness ratio,axial compression ratio on dynamic stability of single-story frame is studied.Relationship curve of ultimate displacement and axial compression ratio are plotted.Then,anti-collapse design advice to single-story steel frames in practical engineering is put forward.
