摘要:

分析了现行砌体结构设计规范中关于垫块下砌体局部受压承载力计算公式的不足,基于偏心受压砌体受力的特点,对现有受压砌体的应力-应变关系进行了修正,并提出砌体偏心受压时的应力-应变关系;利用平截面假定和截面平衡务件,推导出刚性垫块下砌体局部受压承载力计算公式,该式具有计算简单、概念清楚等特点,并能与梁端砌体局部受压承载力的计算相协调,且计算结果与试验结果吻合较好.其结果对砌体的受压承载力分析也有参考作用,可供砌体结构设计规范修订时参考,

Abstract:

The shortcomings of the calculation formula for the local compressive bearing capacity of masonry under the pad were analyzed in the current masonry structure design code, and the stress-strain relationship of the existing compressed masonry was revised based on the characteristics of eccentric compression masonry, and the stress-strain relationship when the masonry was eccentrily compressed. Using the flat section assumption and cross-section balance member, the calculation formula of local compressive bearing capacity of masonry under rigid pad is derived, which has the characteristics of simple calculation and clear concept, and can be coordinated with the calculation of local compressive bearing capacity of beam end masonry, and the calculation results are in good agreement with the test results. The results also have a reference effect on the analysis of the compressive bearing capacity of masonry, which can be used as a reference for the revision of masonry structure design specifications.
