考虑现浇楼板影响的有效翼缘宽度取值探讨
|
摘要
阐述有效翼缘宽度的取值方法及其与受压区"翼缘计算宽度"的区别,在国内外试验和数值模拟研究的基础上对国内外规范在有效翼缘宽度取值上的规定进行比较和讨论,并通过有限元分析对有效翼缘宽度取值的影响因素之一——楼板配筋率进行分析,为合理考虑现浇楼板对框架梁端实际承载能力带来的有利影响提供参考.
The definition of effective flange width was introduced,and the difference between it and the flange calculation width in the mid-span of beam were compared.The provisions about effective flange width in some representative codes of other countries were given and discussed.Some relative research in experiments and FEA simulation was described.Furthermore,in order to get a more resonable calculation formula of the effective flange width to consider the favorable effect of monolithic slab for the flexural capacity of beam end,the main influence factors of effective flange width were analyzed.
