摘要(Abstract):

在获得钢材和混凝土在多轴应力状态时的本构关系的研究成果的基础上,把钢管混凝土视为一种组合的统一体.利用对其轴心受压和纯剪工作性能的研究结果,提出了确定组合抗压强度、组合抗剪强度以及组合模量等设计指标.
Based on the constitutive relationships obtained from steel and concrete under multi-stresses state, author puts forward a conception to regard the CFST member as a unified composite material to research its composite characters. The behavior of axial compression and pure shear of members are analyzed. From the load deformation profiles, the composite compressive and shearing strength indexes and elastic modulus are determined respectively

关键词(KeyWords): 钢管混凝土;轴压;纯剪全过程曲线;组合抗压;抗剪强度指标;组合模量
