以设防烈度为8度的某多层钢筋混凝土框架办公楼设计为工程背景,针对纯框架考虑楼板影响和同时考虑楼板与填充墙影响等三种情况,分别进行Pushover分析,结果表明在进行钢筋混凝土框架结构的抗震设计时,必须适当考虑现浇板与填充墙的影响;通过改变柱端弯矩增大系数的取值,研究二级钢筋混凝土框架的弯矩增大系数的合理取值,表明我国2010年规范对二级框架结构的柱端弯矩增大系数偏小,该值在1.85及以上时,能更好地实现延性框架结构设计。
Taking the design of a multi-storey reinforced concrete frame office building with fortification intensity as 8 degree as the engineering background, the Pushover analysis is carried out considering the influence of the floorboard and the impact of the floorboard and the filling wall considering the pure frame. The results show that in the case of reinforced concrete When considering the seismic design of frame structure, the influence of cast-in-place slabs and infill walls must be properly considered. By changing the value of the coefficient of increasing moment of column end, the reasonable value of the moment increasing factor of second- China’s 2010 standard on the two-stage frame column bending moment increasing factor is small, the value of 1.85 and above, to better achieve the ductile frame structure design.
