【摘要】 《砌体结构设计规范》GB50003 2001关于梁端有效支承长度采用了简化计算公式。在设计中,可能出现不设置刚性垫块时满足规范要求,设置刚性垫块后反而不满足规范要求或有时无论怎样设置刚性垫块,均难以满足砌体局部受压承载力的要求。本文作者通过分析,提出了梁端支承处设有混凝土刚性垫块时砌体局部受压承载力计算的改进方法,可供设计时参考。更多还原

【Abstract】 The simplified calculation formula for effective support length of end beam is determined by the code (GB50003-2001) for design of masonry structure.In masonry structure design,local bearing compressive capacity of masonry without rigid cushion block accords with the code requirement,while local bearing compressive capacity of masonry with rigid cushion block can’t accord with the code requirement.Sometimes,the bearing requirement of bearing compressive of masonry with any rigid concrete cushion block can’t be contented according to the code.An improved calculation method on the local bearing compressive of end beam with rigid concrete cushion block is presented,which can provide reference for designer.更多还原
