【摘要】 本文对钢筋砼框架和桁架的承载能力、刚度及延性,特别是在横向循环荷载作用下的钢筋砼桁架的非线性滞回特性和延性进行了试验研究。试验结果表明钢筋砼桁架具有很好的承载能力、刚度、延性以及很好的经济指标。在试验数据的基础上给出了钢筋砼桁架刚度退化的初步模式。更多还原

【Abstract】 An experimetal investigation into the ultimate load, stiffness,and ductility of R.C. frame and truss, especially their nonelastic behavior, hys-tcretic characteristics,and ductility under cyclic lateral loading,is described in this paper.The experimental results show that R.C.truss has excellent characteristics in the matter of ultimate load,stiffness,and ductility as well as of economy. On the basis of experimental data, a preliminary restoring force model of R.C.truss is given.更多还原
