摘　　要：通过框支墙梁在竖向荷载作用下的试验内力分析 ,认定有限元分析结果总体上与试验符合。分别进行单跨和 2～ 4跨框支墙梁的有限元分析 ,摸清其内力和应力分布 ,给出托梁和框支柱内力近似计算公式。在试验研究和有限元分析的基础上提出框支墙梁承载力计算建议 。That the results of finite element analyses tally with the test results is supposed based upon the test inner force analyses for the wall\|beams supported on frame under the vertical loading. The finite element analyses of single span and 2～4 span wall beams supported on frame are carried out respectively, and the formulas for inner forces of bressumer and frame column are given. The suggestions for calculation of bearing capacity of the wall beams supported on frame are presented based upon the experimental research and the finite element analysis. The calculated example and comparison between this method and others are given.
