, 2015 为了研究活性粉末混凝土(RPC)梁柱节点的抗震性能,本文运用有限元软件ABAQUS,对22个RPC梁柱节点进行分析,得到各节点的滞回曲线和骨架曲线,研究柱端轴压比、节点核芯区箍筋配筋率和梁、柱纵筋配筋率对RPC梁柱节点的滞回特性、延性、承载力等抗震性能的影响规律.研究发现,RPC梁柱节点与高强混凝土梁柱节点受力变化规律基本一致.随着轴压比的增加,RPC梁柱节点延性显著下降,当轴压比低于0.6时,构件极限承载力随轴压比增加而增加,当轴压比高于0.6时,构件极限承载力开始呈现下降趋势 ...

为有效预测车辆履带系统动力学响应,应用非线性有限元描述了履带、地面及负重轮之间的接触,并建立了数学模型。在增量方程的基础上采用有限单元法解决了接触边界值问题,在半圆形和等腰梯形两种路面,干沙、粘土和沙壤土3种土壤及不同负重轮位置和履带刚度条件下进行了算例分析。结果表明:车辆在等腰梯形和半圆形路面行驶时,两个边角接地压力最大;路面越软,履带接地压力越小,且越均匀;负重轮间距和沉陷量越小,履带最大接地压力越大;履带张力和负重轮上反作用力随着履带刚度的增加而增大。建立的数学模型能够合理预测履带张力变化 ...
