摘　　要：为了减小部分作用组合梁的粘结层滑移,将剪切连接件进行"三角形"重新分布的优化设计,并且推导出优化后滑移的具体表达式。通过数值算例将优化结果与未优化结果进行比较,发现优化后的粘结层滑移明显减小,为实际工程中剪切连接件的布置提供了合理的参考和依据。The shear connectors of partial-interaction composite beams are redistributed along the span with ＂triangular shape＂ in order to decrease the interlayer slip. Then the expressions of interlayer slip are derived after the optimal design. Through numerical calculation and analysis between the results with optimization and the one without, it is found that the interlayer slip is reduced significantly, which provides a reasonable reference and basis for the design of shear connectors.

关 键 词：部分作用组合梁 剪切连接件 滑移 优化
