对10个配筋砌块砌体柱进行了偏心荷载作用下的承载力试验研究,了解了该类柱子的受力与变形性能、破坏过程与形态等特征,考察了偏心距、芯柱纵向钢筋等因素对承载力的影响,并对截面应变和芯柱钢筋应力进行了加载全过程记录。借助钢筋混凝土结构的分析方法,推导了配筋砌块砌体柱在偏心荷载作用下的承载力公式,该方法在形式上与普通混凝土偏心受压构件保持了一致性,但在纵向弯曲对承载力的影响上又借鉴了砌体结构的表达式,试验结果证明这一方法是得当的。
The bearing capacity of ten reinforced block masonry columns subjected to eccentric load was studied. The mechanical and deformation properties, failure process and morphology of the columns were also studied. The eccentricity, And other factors on the bearing capacity of the impact, and the cross-section strain and the core column stress was loaded the entire process of recording. With the analysis method of reinforced concrete structure, the formula of bearing capacity of reinforced masonry column under eccentric load is deduced. The method is consistent with the eccentric compression member of ordinary concrete in form, but in the longitudinal bending, The influence of force also draws on the expression of masonry structure, the experimental results show that this method is appropriate.
