基于刚塑性极限理论新型复合砌块砌体抗剪强度计算方法研究

摘要

The shear strength of new composite block masonry has been tested. Based on rigid-plastic limit theory and the least energy consumption principle,the theoretical analysis on the shear strength of new composite block masonry is made and the shear strength calculating formula is given. According to regression analysis of the experimental data, the coefficient of theoretical calculation is determined, and the practical calculating formula is obtained. The results of the formula are in accordance with the results of the shear strength test.%通过试验研究新型复合砌块砌体的抗剪强度,并利用刚塑性极限理论和最小耗能原理对此种新型复合砌块砌体抗剪强度进行了理论分析,提出抗剪强度理论计算公式.通过试验数据的回归分析,确定了理论计算式中的各系数,得到实用计算式,且与试验值对比,拟合良好.
