In order to address the performance complexity of the various constituent materials of (dense-column) latticed concrete-gypsum composite panels and the difficulty in the determination of the various elastic constants, this paper presented a detailed structural analysis of the (dense-column) latticed concrete-gypsum composite panel and proposed a feasible technical solution to simplified calculation. In conformity with mechanical rules, a typical panel element was selected and divided into two homogenous composite sub-elements and a secondary homogenous element, respectively for solution, thus establishing an equivalence of the composite panel to a simple homogenous panel and obtaining the effective formulas for calculating the various elastic constants. Finally, the calculation results and the experimental results were compared, which revealed that the calculation method was correct and reliable and could meet the calculation needs of practical engineering and provide a theoretical basis for simplified calculation for studies on composite panel elements and structures as well as a reference for calculations of other panels.
为了解决（密柱式）格构混凝土-石膏复合板各种组成材料的性能复杂性以及各种弹性常数确定的困难，本文对（密柱式）格构混凝土-石膏复合板进行了详细的结构分析，并提出了一种可行的简化计算技术方案。按照力学规则，选取典型的板单元并分别划分为两个均质复合子单元和一个次生均质单元进行求解，从而建立复合板与简单均质板的等效性，得出计算各种弹性常数的有效公式。最后，将计算结果与试验结果进行比较，结果表明该计算方法正确可靠，能够满足实际工程的计算需求，为复合板单元及结构的简化计算研究提供理论依据，也为其他板的计算提供参考。
