摘要

摘要: 对钢管高性能混凝土轴压短柱的静力性能展开研究,以便给辽宁省地方标准的编制提供依据。通过18个试件(内填自密实混凝土的立方试块抗压强度标准值为96MPa)的静力试验,研究试件的破坏模态,发现高性能混凝土具有良好的塑性填充性能,构件的破坏属于强度破坏;分析轴力-钢管纵向应变曲线,发现该曲线可以分为弹性阶段、弹塑性阶段和下降阶段。应用有限元法模拟试件的轴力-钢管纵向应变曲线,模拟结果与试验结果吻合良好。

Abstract: The static performance of the axially compressed high-performance concrete filled steel tubular stub columns was investigated in order to provide foundation for drawing the relative code of Liaoning Province.On the basis of experimental study on 18 specimens(the cubic compressive strength of the in-filled self-consolidating concrete was 96 MPa),the deformed modes of the specimens were studied,it was found that the concrete showed good plastic property and the specimen failure was due to strength loss.The axial load-steel tube longitudinal strain curves were analyzed,it was found that it could be divided into elastic,elasto-plastic and softening stages.The axial load-steel tube longitudinal strain curves were simulated by using FEM and the calculated results checked well with those of tests.
