后张预应力平板－柱结构实用设计方法的研究
|
摘要
首先将后张预应力平板－桂结构的综合弯矩、次弯矩表达成板、柱预应力筋面积的函数，然后提出了预应力硅结构构件裂缝控制及验算建议，最后给出了通过使用性能计算确定板、性预应力筋面积，通过正截面承载力计算和配筋构造要求确定板、柱非预应力筋面积的设计方法，该法避免了以往繁琐的试算过程，并能使使用性能和正截面承载力要求同时达到最佳。
n this poper,both resulting moment and secondary moment are first defined as a functionof cruss-areas of prestreasing steel in flat slab and column. New pruposal about cracking-control of pre-stressed cuncrete structural members is presented,and a practical design method is finally provided, inwhich the amount of prestressing steel in flat slab and culumn is decided by serviceability and that ofnonprestressing steel by ultimate load capacity,By this method,the complicated trial-calculation is elimi-nated,and both serviceability and ultimate load capacity can best be satisfied simultaneously;
