中文摘要：
基于能量原理,提出了在大变形下考虑受拉薄膜效应计算混凝土板承载力改进的能量法,并通过该方法分析了影响受拉薄膜效应产生的主要因素。研究发现,正交系数和特征比对受拉薄膜效应的影响较为显著,而混凝土强度和钢筋配筋率的影响较小。
英文摘要：
Based on energy principle,an improved energy method was proposed to calculate the limit load-carrying capacity of concrete slabs,and tensile membrane action was considered.Many parameters,which have important influence on the tensile membrane action,were discussed using this new method.It is indicated that orthogonal coefficient and aspect ratio have significant influence on the tensile membrane action,but the influence of concrete and steel strength is small.
