[提要] 通過框支墻梁在豎向荷載作用下的試驗(yàn)內(nèi)力分析，認(rèn)定有限元分析結(jié)果總體上與試驗(yàn)符合。分別進(jìn)行單跨和2～4跨框支墻梁的有限元分析，摸清其內(nèi)力和應(yīng)力分布，給出托梁和框支柱內(nèi)力近似計(jì)算公式。在試驗(yàn)研究和有限元分析的基礎(chǔ)上提出框支墻梁承載力計(jì)算建議，給出計(jì)算實(shí)例并與其他設(shè)計(jì)方法進(jìn)行比較。

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.
Keywords: wall-beams supported on frame; experimental research; finite element; calculation; bearing capacity
