摘要
采用非线性有限元程序 ,对预应力筋集中放置的混凝土板极限承载力、刚度、变形等进行了理论分析和对比计算 ,指出在相同条件下预应力筋集中放置比分散布置可节约钢筋 1/ 3左右 ,经济效益显著。
The ultimate capacity,stiffness and deflection of prestressed concrete slab whose prestressed bars concentrated arrangement were analyzed in theory by non-linear FIM.The results indicate that the amount of prestressed reinforcement csn economize around one-third than that of usual arrangement of reinforcement,which has a significant economic benefit.
