组合梁剪切连接件改进思考

Thinking about the improvement of composite beams connector

组合梁是在组合结构中应用最为广泛的结构形式之一,其组合作用的大小是由组合梁中的剪切连接件决定的。对现有剪切连接件形式进行了总结,并针对现有连接件的缺点,提出了大型剪切连接件的形式。最后通过有限元分析对栓钉连接件与大型剪切连接件进行比较分析,结果表明,大型剪切连接件的各方面性能均优于普通栓钉连接件。

Composite beam is widely used in composite structure, of which the performance depends on connector. This paper concludes the styles of connector,and proposes large-scale connector by analyzing the disadvantages of usual connector. It is concluded that the performance of large-scale connector is superior to what of the peg-connector by comparing large-scale connector with peg-connector with finite element analysis.
