| 摘 要： | 本文根据适用于三向周期受力的钢材本构关系模型，和适用于三向周期受力改进的混凝土本构关系的边界面模型，采用有限元法对钢管高强混凝土压弯构件的荷载－位移滞回曲线进行了理论分析，并进行了6个核心混凝土的强度为77N/mm2的钢管高强混凝土压弯构件滞回性能的试验研究。将理论分析和本试验研究及其他试验研究结果进行了对比，分析了荷载－位移滞回曲线的特点。

| Abstract: | In this paper, the force-displacement hysteretic loops of high strength concrete filled steel tubular members under compression and bending are calculated using element method with a steel constitutive model which is suitable for multiaxial cyclic loading and for a concrete modified bounding surface model for multiaxial cyclic compression. Six new tests were carried out on steel tubes filled with concrete with a cube strength of 77N/mm2. The theoretical lateral force-displacement hysteretic loops are compared with these tests and tests by other experimentels and the results are discussed. |
