【摘要】 对18根高强混凝土单层、双层、三层配箍短柱在轴压作用下承载力进行了试验研究,分析了其破坏过程,破坏形态。文中着重对比分析了配箍率,配筋形式对试件承载力及延性的影响,得出了采用增加箍筋层数来提高承载力及延性的方法并不可取的结论。更多还原

【Abstract】 Eighteen high-strength concrete puncheons,constrained respectively with monolayer,double deck,three-ply stirrup,are testing under axial pressure,faiure course,failure patterns,carrying capacity and ductility are studied.In this paper,the stirrup rate and stirrup(pattern’s) effect on carrying capacity and ductility are emphasized.According to testing outcome,it’s not proper to use multi-layers stirrups to improve carrying capacity and ductility in practice.更多还原
