对部分包裹钢-混凝土梁柱进行了一系列试验。在轴向重力荷载和极端侧向荷载的理想条件下对构件非弹性性能进行试验。试验构件具有3种不同的横截面尺寸,并由S460级钢材制成。在主次弯曲和持续轴向荷载作用下对构件进行测试。介绍了试验的安排和测试装备,材料特性和构件的详细情况。通过对10个构件进行试验,得出主要结果并对其进行讨论。除了为将来的分析和设计提供关键数据外,试验结果还能为几个重要参数的直接评估提供参考。对涉及到屈服、极限承载能力、延性和残余强度的几个关键参数也进行了重点分析。
A series of experiments were carried out on partially wrapped steel-concrete beams. Under the ideal conditions of axial gravity load and extreme lateral load, the inelastic properties of the member were tested. The test components are available in 3 different cross-sectional sizes and are made of grade S460 steel. The members were tested under primary and secondary bending and sustained axial load. The test arrangement and test equipment, material properties and details of the components are presented. By testing 10 components, the main results were obtained and discussed. In addition to providing critical data for future analysis and design, the results provide a direct reference to several important parameters. Key parameters related to yield, ultimate carrying capacity, ductility and residual strength were also analyzed.
