[摘要]《砌体结构设计规范》(GB50003—2001)建议的连续墙梁内力计算方法较繁琐,不便于设计人员应用。通过2~5跨连续墙梁的有限元分析,根据其应力和内力分布规律,采用一定的简化假定,建立了基于一般连续梁内力分析方法的墙梁内力近似计算公式。将公式计算值与现行规范公式的计算值进行了比较,并通过实例分析,对不同设计方法所得配筋量进行了对比。

Abstract:The design regulations of continuous wall-beams in Code for design of masonry structures GB50003—2001 is too complex to be used by engineers. The finite element analysis of 2~5 span continuous wall-beams were carried out. For inner forces of beam and simplified assumptions, the approximate calculation formulas of bearing capacity for the continuous wall-beams was presented,which was based on the analysis method of continuous beams. The calculation values were compared with the code results. The calculated example and the comparison between this method and others were given.
Keywords:continuous wall-beams; finite element analysis; simplified calculating formulas
