摘要
采用ETABS程序分析了在框架结构抗震计算中采用未考虑楼梯构件刚度的传统方法和有限元的精确计算方法两种计算模型,探讨了采用精确计算模型时楼梯构件板厚、开间、混凝土强度等级、进深的变化对整体结构计算结果的影响,提出了采用斜杆模拟楼梯构件以简化模型的计算方法,通过对比,验证了简化方法在工程设计中的可行性。
The traditional method without the regard to the stair components rigidity and the accurate calculation method of finite elements in the frame and structure seismic calculation are analyzed with the ETABS. The influence of change in the plate thickness, bay, concrete strength grade and depth of stair components on the whole structure calculation results in the accurate calculation model is discussed, the calcu- lation method of simplify the model by simulating the stair components with diagonals is proposed, through the contrast, the feasibility of simplified method in the construction design is verified.
