【摘要】 采用传递矩阵法,研究了组合梁连接键布置方式对组合梁工作性能的影响。首先以梁轴心受力和弯曲为例,介绍传递矩阵法的基本原理,然后根据组合梁的等曲率假设,推导组合梁的场传递矩阵和点传递矩阵,编制传递矩阵法计算组合梁的计算程序。最后通过算例研究,分析了3种连接键布置方式对组合梁工作性能的影响。计算结果表明,对组合梁进行连接键优化布置是可行的。更多还原

【Abstract】 The influence of arrangement of shear connectors on structural behaviors of composite beam is studied by transfer matrix method.The basic principle of the transfer matrix method is introduced through beam subjected to axial force and bending moment.Then,the field and the point transfer matrix is derived based on the assumption of single curvature,and the calculation program for the composite beam is developed subsequently.Finally,the influence of three kinds of arrangement of shear connectors on the structural behaviors of the composite beam is analyzed through numerical examples.The results indicate that it is practical to optimum the arrangement of shear connectors of the composite beam.更多还原
