摘　　要：本文提出了钢纤维高强砼软化应力-应变关系。应用软化桁架理论,对钢纤维高强砼低剪力墙的受力全过程进行了分析。结果表明,计算理论值与试验结果符合程度较好。在此基础上,提出了低剪力墙抗剪能力的计算公式。The softened stress-strain relationship of steel fiber high strength concrete ( SFHSC) is presented in this paper. The analysis of low-rise SFHSC shear walls throughout loading history has been carried out by use of the theory of softened truss. The results of theoretic calculation and those by tests show good agreement. Besides, formula for predicting ultimate shear strength of low-rise shear wall has been proposed as well.
