摘要
为了探索装配整体式混凝土结构的抗震性能和实用性,提出一种由复合螺旋箍约束的混凝土通过外包钢板箍和横穿螺栓连接形成的新型装配整体式柱。通过不同轴压比下2个装配试件的拟静力加载试验和相同条件下2个整体试件的试验对比,以及采用有限元软件ABAQUS对部分构件的试验数据进行验证,得知该装配式柱的整体性和整体柱相当。该装配式柱抗震性能好,且绿色、高效,可在实际工程中代替整体柱。
In order to research the anti-seismic and practical property of the precast structure, a new assembled monolithic concrete column, which consists of two concrete columns reinforced by high-strength compound spiral hoop and jointed by encased steel and bolts is presented. Experiments of two precast specimens under low cyclic loading and different axial compressive forces are carried out, and the finite element software ABAQUS is used to verify the experimental results of the specimens PRCC-L02 and C-01. The results testify that the anti-seismic prop- erty of this measure is not worse than the monotonic specimens and can substitute for the monotonic columns in practice.
