介绍了连续组合梁的分析和设计方法。采用数值分析方法确定了设计中采用的板的有效宽度，并对负弯矩区裂缝的影响进行了评估。讨论了有效宽度概念的一些不足之处。评估了开裂对正常使用条件和弹性设计的影响，并提出了设计的近似方法。塑性设计方法根据在中垂和中拱力矩中可用的铰链转动进行讨论，特别参考了塑性方法（a）适用性极限的分析和实验研究。
Methods of analysis and design of continuous composite beams are presented. Numerical analysis is used to determine the effective width of slab to be used in design, and the influence of cracking in the negative moment region assessed. Some shortcomings of the effective width concept are discussed. The effects of cracking on serviceability conditions and elastic design are assessed, and approximate methods for design suggested. Plastic design methods are discussed in terms of available hinge rotation in sagging and hogging moment, with particular reference to analytical and experimental studies at the limits of applicability of the plastic method (a).
