新型夹芯板斜截面承载力的理论分析

Principle study of the shear strength of new-style concrete sandwich panel

钢筋混凝土夹芯板(CS板)是一种新型的环保、节能型结构构件,在结构中不仅可用作围护结构还可以作为承重构件使用.本文研究目的是对CS板的抗剪性能进行理论分析,阐述其抗剪传力机理;通过对3块CS板进行抗剪实验,观测其受力性能的变化,提出计算模型和计算公式,将用该计算公式所得结果与实测结果相比较,二者吻合较好,该计算模型和公式可供工程设计中参考使用.

CS panel is a kind of new-style building block. Since such a panel construct has the features of protecting environment and saving energy, it is used as a fender structure in structure. This paper puts emphasis on the analysis of the shear mechanism of concrete Sandwich panel, and its shearing resistance performance as well. The calculative model and the theoretical formula are proposed, the results of the calculation and those of the test are compared and turn out to be consistent properly. Therefore, this paper can serve as a reference for the engineering design of CS panel.
