摘要
对交错桁架体系的抗震性能进行了分析 ,建立了单向水平地震作用下交错桁架体系协同分析的力学模型。在动力时程分析的过程中考虑了构件的剪切变形 ,并在单元水平上考虑了几何非线性。通过交错桁架体系设计实例的弹性和弹塑性时程分析 。
The aseismic behavior of a staggered?truss system is studied in the paper. A mechanical model is proposed to study the system under the action of one?direction earthquake. At the same time, a program is developed for the analysis. The shear effect is considered in the time?history analysis;the geometrical nonlinear effect is considered in the element level An example is made to evaluate the behavior of the system by the elastic and elasto?plastic time?history analysis. An example is made to evaluate the behavior of the system by the elastic and elastio?plastic time?history analysis.
