COMPARISON OF FORCE-BASED SEISMIC DESIGN METHOD WITH DISPLACEMENT-BASED SEISMIC DESIGN METHOD
-
摘要: 首先用基于力的抗震设计方法对一幢8层钢筋混凝土框架结构房屋进行了抗震设计,然后将建筑结构的性能划分为使用良好、保证人身安全和防止倒塌三个水平,给出了相应的层间位移角限值,分别计算了三个性能水平对应的结构基底剪力和顶点位移,以及使用良好和防止倒塌两种性能水平时的构件截面配筋。用静力非线性分析方法对计算结果进行了验证性分析。最后对两种设计方法及计算结果进行了比较分析。分析结果表明,按使用良好性能水平设计的构件截面配筋量与基于力的方法所得结果比较接近。

Abstract: A 8-story reinforced concrete frame structure is designed by using the force-based seismic design method.Then, the performance of frame structure is divided into three levels: serviceability, life-safety, and collapse protection. The three levels are quantified with story drift ratios, base shear and top displacement of the structure is calculated for three performance levels. For serviceability and collapse protection, the members is proportioned and the appropriate reinforcement selected, and details of seismic design is taken to ensure the deformability of the structure. The calculation results are verified by non-linear static analysis method. The results of two design methods are compared. Analysis result shows the members section reinforcements based on serviceability performance level are close to those by the force-based seismic design. -
