摘要:
对10个单向受力石楼板的受弯性能进行试验,重点研究石板的受弯破坏形态、沿截面高度的应变分布规律和受弯承载力.试验结果表明:石板受弯破坏形态为完全脆性破坏,其受弯承载力主要受石板截面尺寸和石材天然缺陷所控制,存在一定离散型; 石板断裂破坏前,横截面应变沿高度方向的分布基本上呈线性,符合平截面假定.基于平截面假定和试验结果统计分析,提出石楼板的受弯承载力计算公式,理论计算结果与试验结果吻合较好.
Abstract:
10 one-way stone slabs were tested to investigate the flexural behavior.The failure mode,strain distribution of cross-section and flexural bearing capacity of stone slabs were studied.The results indicate that the failure mode of stone slabs is brittle rupture; the control conditions of flexural capacity are the cross-section of stone slabs and natural defects of stone.Before the failure of stone slabs,cross-section strain distribution along the height is linear,and the plane-section assumption is valid.Based on the test results and the plane-section assumption,an analytical model is proposed to calculate the cracking moment of stone slabs.The proposed model agrees well to the experimental results.
