[摘要]基于构造柱-圈梁这一特殊形式的约束砌体结构的特点和其在抗震中的显著作用,以及不同配筋砌体构件对配筋率的要求,较好地定义了无筋、配筋及约束砌体构件,并对约束配筋砌体构件在抗震设计中的定位和界定提出了建议,可供修订《建筑抗震设计规范》和《砌体结构设计规范》参考。
[关键词]无筋砌体构件;配筋砌体构件;约束砌体构件;抗震设计

Abstract:Based on the properties of confined masonry structures composed of structural concrete column and ring beam, and its remarkable action in earthquake resistance and requisite reinforcement ratio for different reinforced masonry structures, the definitions of unreinforced masonry member, reinforced masonry member and confined masonry member are proposed. The orientation and demarcation of confined masonry member in seismic design are recommended. The results can provide reference for the revision of current codes.
Keywords:unreinforced masonry members; reinforced masonry members; confined masonry members; seismic design
