| 摘 要： | 钢筋混凝土框架结构连续倒塌的分析涉及到砼开裂、混凝土和钢筋的材料非线性、结构的几何非线性等因素,目前通用的有限元分析软件尚不能对此进行有效的计算。本文考虑了材料非线性及P-△效应,采用塑性铰假设,设定了倒塌判定条件,用FORTRAN90编写静力非线性有限元分析程序,对钢筋混凝土框架结构进行了倒塌分析。

| Abstract: | The three-level performance objective is put forward in national code for seismic design of buildings,that is,the criterion of no damage under frequent earthquake,repairable damage under moderate earthquake,no collapse under severe earthquake,but the objective is guaranteed mainly by the empirical adjustive coefficient and strengthening of construction details.The second level and third level performance objectives,that is,repairable damage under moderate earthquake and no collapse under severe earthquake,l... |
