摘　　要：介绍了一种通过积分计算侧移的方法,利用各截面的曲率分布,计算屈服位移和极限位移,通过计算把握钢筋混凝土柱构件的位移性能获得柱构件的弹塑性位移,并求得该状况下柱构件的位移延性,从而由曲率分布获得构件位移延性性能,该方法简单实用,便于操作,值得推广。This thesis introduces integral calculating sidesway method,uses the section curvature,and calculates yield displacement and ultimate displacement.Through calculation,it grasps the displacement performance of reinforced concrete member,and obtains the elastic-plastic displacement of the column member,and acquires the displacement ductility of the column member,and further gets the displacement ductility performance through curvature distribution.This method is simple and practical and operational.Thus,it is worth promoting.
