摘要

. 面内加载砌体面板的安全性验证需要评估至少三种不同的破坏条件,包括面板趾部的倾覆、剪切滑动和剪切压缩破坏。在加筋板中,抗力模型甚至应考虑局部或分布钢筋的存在。一般认为砌体是一种不抗拉、抗压塑性的莫尔-库仑型材料,而钢筋则是一种仅抗拉的脆性弹性材料[1]。然而,最终极限状态与面板区域内给定的压缩材料子集有关。因此,作为施加载荷的函数,被压缩的部分在面板内部变化。当某一特殊压缩截面减小到最小值时,发生剪切或倾覆破坏[2]。

Combined Shear-Flexural Verification of in Plane Loaded Reinforced and Unreinforced Masonry Walls
. The safety verification of in-plane loaded masonry panels requires the evaluation of at least three different collapse conditions connected with overturning, shear sliding, and shear – compression failure at the panels’ toe. In reinforced panels , the resisting models should even take into consideration the presence of localized or distributed reinforcement. In general, the masonry is considered a Mohr-Coulomb type material not resisting tension and plastic in compression, while reinforcement is a brittle elastic material resisting tensile forces only [1]. The ultimate limit state is however linked with a given subset of compressed material inside the panel area. The compressed sections are therefore varying inside the panel as a function of the applied load. The collapse occurs in shear or overturning when one peculiar compressed section reduces to its minimum [2].
