钢筋混凝土轴心受压构件的非线性稳定性
Nonlinear stability of uniaxial compressive reinforced concrete members
摘要
Abstract
Based on the relationship between stress and strain provisioned in "Code for design of concrete structures" (GB50010-2002) and taking concrete strength, slenderness ratio and concrete creep as study parameters, the bearing capacity of uniaxial compressive reinforced concrete members is studied from nonlinear theory's viewpoint and longitudinal bending coefficient in concrete critical state is obtained. It is indicated that the concrete creep has a significant effect on the bearing capa members. When concrete creep is not a factor, bearing capacity of uniaxially city of uniaxial compressed compressed members cornputed in this paper is greater than that in the standard, but is much smaller than that of the standard while it is a factor. Therefore, further studies should be made on the influence of creep to the bearing capacity of uniaxial compressive reinforced concrete member.关键词
