摘要
本文应用自制的试验装置对平面应变状态下混凝土的变形和强度特性进行了试验研究;比较了平面应变与平面应力状态下混凝土的变形和强度特性间的差别;给出了在弹塑性状态下,两种平面问题间的应力转换关系,为简化平面应变问题的非线性分析及充分利用混凝土在复杂应力状态下的强度提供了试验及理论根据.
The behaviors of deformation and strength of concrete under plane strain condition are studied experimentally with the triaxial apparatus designed by the authors.The above mentioned behaviors are discussed and compared with that under plane stress condition. In elasto-plastic state, the stress transform formula between plane stress and plane strain conditions is also proposed, and it would play on important role in simplifying nonlinear analysis and fully using the strength of concrete.
