摘要
墙梁结构受力机理有其独特的特性。采用自编的有限元计算程序分析了在竖向荷载作用下,顶梁、边柱对墙梁应力的影响。通过对比,得出边柱在减小墙梁跨中的竖向位移和拱效应的加强作用中起支配作用,而顶梁随着墙高的增加对墙梁跨中的竖向位移和拱效应的影响逐渐减弱的结论。
The bearing mechanism of wall beam structure is possessed of unique speciality.The finite element program which the author compiled is used here to analyze the influence of the top beam and edge column on the stress of wall beam under vertical load.Through contrasting,the conclusion is drawn that the edge column has a predominant effect on diminishing the beam＇s mid-span vertical displacement and enhancing the arch effect,but the effect of head beam on them becomes less with the heightening of wall.
