In this paper, the effects of partial shear connection on the behavior of semi-continuous composite beams were studied numerically using two-dimensional finite element model with plane stress elements. The finite element model takes into account the nonlinearity of the different materials involved. For the shear connectors, a non-linear (shear-slip) relation, drawn from the push-out tests, was used. The accuracy of the proposed finite element model was verified against test results available in the literature. A simplified method to predict load capacity and deflection of the semi-continuous composite beams was also proposed. Based on the results obtained from the finite element analysis, the concept of partial shear connection in the hogging moment regions can be accepted provided that the shear connectors are sufficiently ductile.

部分剪力连接对半连续组合梁性能的影响

本文利用带有平面应力单元的二维有限元模型，数值研究了局部剪力连接对半连续组合梁性能的影响。有限元模型考虑了所涉及的不同材料的非线性。对于剪切连接器，使用了从推出测试中得出的非线性（剪切滑移）关系。相对于文献中提供的测试结果，验证了所提出的有限元模型的准确性。还提出了一种简化的预测半连续组合梁承载力和挠度的方法。根据有限元分析获得的结果，只要剪切连接器具有足够的延展性，就可以接受在弯矩区域内进行局部剪切连接的概念。
