抗震结构节点内梁纵筋粘结滑移的模型化方法
|
摘要
大量试验结果表明 ,在罕遇地震作用下节点核心区内梁纵筋的粘结滑移是钢筋混凝土结构的一种比较常见的局部非线性反应。为了更全面、合理地评价和模拟钢筋混凝土结构的抗震性能 ,分析了在结构的弹塑性地震反应中 ,节点核心区内梁纵向受力钢筋粘结滑移量及其滞变规律的模拟方法 ,并分别评价了几种考虑节点核心区内纵筋粘结滑移影响的结构分析方法各自的特点 ,然后基于已有的试验结果 ,给出了节点核心区内梁纵筋的粘结滑移滞回曲线的一个模型化方法 ,并对该模型的相关问题进行了讨论
Many experimental results indicates, beam bar slippage within joints is a frequent local nonlinear response of reinforced concrete structures under the rare earthquakes. For the sake of modeling and evaluating seismic behaviors of reinforced concrete structures entirely and rational, the model way of the quantity and hysteresis order of beam bar slippage within joints, which was found in the elasto plastic earthquake response of structures, is discussed thoroughly. And the personal characteristics of several structure analysis ways to model the beam bar slippage within joints are evaluated respectively. Based on the results already gotten, a hysteresis model of beam bar slippage within frame joints is advanced, and the relative issues are also discussed. The beam bar slippage model suggested is convenience to the elasto plastic dynamic response analysis of whole reinforced concrete structures.
