[提要] 給出6個承重多孔磚砌體框支墻梁在均布荷載作用下的試驗結(jié)果。討論了墻體高跨比、框架梁與柱的線剛度比及框架梁縱向鋼筋配筋率對框支墻梁受力性能與承載力的影響。基于4條假定對框支墻梁進行塑性極限分析,給出受彎、受剪承載力計算公式。與試驗結(jié)果符合良好。
[關(guān)鍵詞] 框支墻梁 破壞形態(tài) 承載力 塑性分析The test results on six specimens of the perforated brick masonry walls supported on frame are given. The influence of height - span ratio of walls, beam - column rigid ratio of frame and percentage of longitudinal bars of beam on the behaviour and strength are discussed. The plastic limit analyses for bearing capacity of walls - frame composite structures are carried out based on 4 basic assumptions and the formulas'of their flexural and shear strength, which tally with test results are presented.
