国内外规范对板柱边角节点冲切承载力计算的比较
|
摘要
列举了国内外规范中关于钢筋混凝土板柱结构边节点和角节点抗冲切承载力的计算表达式,根据选取的影响参数,了解不同国家规范的差异性,并且结合已有试验进行数值对比和分析。研究结果表明,不同国家规范中的设计公式与参数选取有明显的差异,且通过数值对比可知,国外规范相比中国规范在抗冲切承载力设计取值方面更加保守。
The different codes of home and abroad about the design formula of punching shear capacity for reinforced concrete slab-column edge and corner connections were listed,their differences were known according to the selected parameters,and the existing experimental data were compared and analyzed.The research results show that the design formula and the parameters in codes of different countries have obvious differences,and comparative study results show that the calculation results in foreign codes are more conservatives than the Chinese codes.
