摘要
将同济大学李国平提出的体外钢筋极限应力和有效高度求解简化公式运用到体外CFRP预应力筋混凝土连续梁极限承载力的计算推导中,据此得出混凝土连续梁极限承载力。然后用新加坡国立大学Kiang Hwee Tan andRobert A.Tjandra等人所做的试验结果进行比较,比较结果表明理论推导值与实验值相差不大。
The paper makes calculation and reasoning about ultimate stress of external CFRP prestressed reinforced concrete continuous beam with simplified formula of Li Guoping of Tongji University about limit stress and effective height.And the ultimate stress of continuous concrete beam will be obtained.Then,the conclusion will be compared with the experimental values made by Kiang Hwee Tan and Robert A.Tjandra in Singapore National University.The compared results indicated that theoretical predictions haven＇t difference with experimental values.
