基于部分剪力连接模型,利用结构力学的基本原理,同时考虑了各种因素的影响,对不同工况作用下的连续组合板的极限承载力计算方法进行了推导。与国内外的连续组合板试验结果的对比表明,提出的计算方法能够较为准确地计算连续组合板的极限承载力。通过改变不同的参数,对影响连续组合板极限承载力的主要参数进行了分析,提出了实际工程中宜遵循的原则。最后给出了实用的设计表达式。
Based on the partial shear connection model and using the basic principle of structural mechanics, considering the influence of various factors, the calculation method of the ultimate bearing capacity of continuous composite plates under different working conditions is deduced. Compared with the results of continuous composite panels at home and abroad, the proposed calculation method can calculate the ultimate bearing capacity of continuous composite panels more accurately. By changing different parameters, the main parameters that affect the ultimate bearing capacity of continuous composite plates are analyzed, and the principles that should be followed in practical projects are put forward. Finally, a practical design expression is given.
