摘　　要：依据国内外对砌体受压本构关系的研究成果,总结了影响砌体受压本构关系的主要因素;提出了反映上述主要因素的砌体受压本构关系统一模式.该模型适用于各类砌体、不同受力状态、加载方式、加载方向以及加载速率、是否存在横向水平约束等不同情形,具有广泛适用性.The main factors influencing the compressive constitutive relations of masonry were summarized on the basis of research results of the compressive constitutive relations of masonry at home and abroad. A unified model of the compressive constitutive relations of masonry has been proposed to reflect the aforementioned main factors. This model has been applied to all kinds of masonry, different stressstate, loading styles, loading directions and rate and existing horizontal constraint. It has widespread adaptability and can provide reference for masonry structural analysis and research.
