钢筋混凝土开孔梁的研究进展
Research Development on Reinforced Concrete Beams with Openings
【摘要】 在建筑结构中,采用钢筋混凝土开孔梁,让各种管道等辅助设施从构件中穿过,可以有效节约建筑空间,降低工程造价。介绍了当前钢筋混凝土开孔梁的国内外研究现状,对钢筋混凝土开孔梁进行了分类探讨,阐述了钢筋混凝土开孔梁的受力性能、破坏形态、抗剪强度计算、变形和裂缝特征等主要研究成果。并进一步介绍了钢筋混凝土开孔梁的抗震性能的研究及有限元分析方法,对今后钢筋混凝土开孔梁的研究提出了建议。
【Abstract】 In architecture structure,the use of reinforced concrete beams with openings may effectively save the building space and reduce the cost for the passage of various pipes of auxiliary facilities.The paper presents an analytical discussion of current research and findings on reinforced concrete beams with openings at home and abroad,covering its classification,mechanical property,modes of collapse,calculation of shear strength,deflection and crack characteristics.In addition,the seismic performance and finite element analysis method are introduced in brief,and suggestions are offered for further research.
【Key words】 reinforced concrete; opening beams; mechanical property; collapse modes; crackc haracteristics; seismic performance;
