剪力连接度对组合梁非线性的影响

Effect of Shear Connection Degree on Nonlinear Behavior of Composite Beams

在组合梁参数化有限元模型的基础上,改变连接件间距,进行了6根不同剪力连接度组合梁的非线性分析.结果表明:当剪力连接度大于0.6时,适当地改变其大小对组合梁非线性性能影响较小,实际工程中使用部分连接组合梁是切实可行的.

Based on the parametric finite element model of composite beams,the nonlinear analysis of 6 composite beams with different shear connection degrees is carried out by changing the space between the connectors.The analysis shows that when the shear connection degree is greater than 0.6,it has little effect on the nonlinear performance of the composite beam to change its size appropriately,and it is feasible to use the partially connected composite beam in the actual engineering.
