Through the later three conditions of impact load, the results showed that : according to the difference between impact positions can also be selectively framework was further reduced to take into account cross-shaped structure or a single end-column constraint column model frame columns impact analysis. 通过后面3种撞击荷载工况分析,结果表明:根据撞击部位的不同,也可以有选择地将框架进一步简化为十字形结构或考虑柱端约束的单根柱模型进行框架柱的抗冲击分析。
Finally, based on the existing single fiber rectangular column confined concrete strength of the model, and gives out the hybrid fiber strength model. And through the linear regression coefficient that effectiveness. 最后,结合已有的单一纤维约束混凝土矩形柱的强度模型,给出了混杂纤维强度模型,并分别对单一纤维与混杂纤维有效性系数进行了回归。
The dynamic mechanics feature and its regularity of the whole plate girder bridge with single column are researched. By compared with real bridge dynamic experiment data, the theoretical model data is tested. 研究独柱整体式板梁桥的动力特性及其规律性,并结合实桥动载试验数据,对理论模型计算结果进行检验。
The concrete filled steel tubular columns are designed as a group of columns with large flexibility. This paper presents the design of single column, the internal force analysis of the columns group and the results of loading test on a 1 : 2 model. 所设计的钢管砼窑底柱是一组大柔度钢管砼群柱,本文介绍其单柱设计、群柱内力分析,以及1:2单柱模型(SCM)模拟加载试验的结果。
