什么是刚度突变

基础刚度突变
1.Analytical deformation formula of the continuous beam under moving loads has been derived by establishing the vibration differential equation of the continuous beam with foundation elasticity stiffness abrupt change.3) abruptness of lateral stiffness
侧向刚度突变
1.By extensive computational analysis of several kinds of tall building structures and investigation of relative earthquake damage reports,the influencing factors,the control methods and the affects on seismic behaviors of the abruptness of lateral stiffness are studied in this paper.
结合震害资料,通过对算例的深入分析和比较,研究了高层建筑楼层侧向刚度突变的影响因素、控制方法及其对结构抗震性能的影响,对现行规范中层刚度比的控制方法提出了建议和补充。4) lateral stiffness irregularity
