摘要

在简单钢管混凝土组合柱中内嵌H型钢，形成新型组合结构柱，为研究新型组合结构柱的受力性能，对其进行纯弯、压弯、扭弯、压弯扭4个工况的试验研究。为满足试验过程中的加载需要，设计制作了一套适用于多工况模拟的加载装置。在复杂荷载加载中，对于有轴压参与的工况，控制轴压比为0.24；对于有扭弯的工况，控制扭弯比为0.34。通过对4个试件的加载试验，分析其扭矩-扭转角滞回曲线、弯矩-位移滞回曲线、扭矩-扭转角骨架、弯矩-位移骨架、力学特征及刚度退化等指标，对结果及其产生机理进行分析。结果表明，在复杂荷载作用下，该新型组合结构柱受力性能良好。基于试验结果提出在工程实际中使用该新型结构柱的基本建议。

Abstract

In this paper

H-shaped steel is embedded in simple concrete-filled steel tubular composite columns to form a new type of composite structural columns. In order to study the mechanical behavior of the new composite structure columns

the experimental studies are carried out under four working conditions: pure bending

compression-bending

torsion-bending and compression-bending-torsion. In order to meet the loading needs during the test

a set of loading devices suitable for multi-working condition simulation is designed and made. In the loading of complex load

the axial compression ratio is 0.24 for the condition with axial compression

and the torsion-bending ratio is 0.34 for the condition with torsion. Through the loading tests of four specimens

the indexes such as torque-torsion angle hysteresis curve

moment-displacement hysteresis curve

torque-torsion angle skeleton

moment-displacement skeleton

mechanical characteristics and stiffness degradation are analyzed. The results and mechanism are analyzed in depth

and the results show that the mechanical performance is good under complex loads

and the basic suggestions for using this new structure in engineering practice are put forward.
