摘要:
采用3种加载方式对27根钢管轻集料混凝土短柱进行轴压试验,分析了加载方式对构件轴心受压破坏形态和力学性能的影响,主要试验参数为不同轻集料混凝土强度等级和钢管截面尺寸.3种受荷方式分别为:荷载作用在核心混凝土上; 荷载作用在整个截面上; 采用滚轴加载板将荷载作用在整个截面上.研究结果表明,加载方式对钢管轻集料混凝土短柱的轴压变形性能有较大影响,而对其极限承载力影响不大.无论何种加载方式,钢管轻集料混凝土短柱的纵向压缩变形能力都很强,纵向应变可达0.1,因而具有十分良好的延性,并具有较大的后期承载能力.
Abstract:
Based on the experimental study of 27 lightweight aggregate concrete filled steel tube(LACFST)stub columns under three types of loading conditions, influence of the loading conditions on the failure pattern and mechanical behavior of the specimens are studied. The main experimental parameters are different grades of lightweight concrete intensity and cross sectional sizes of steel tubes. The three loading conditions are: compressive load on concrete only; compressive load on steel tube and concrete simultaneously; compressive load passing through a roller located at the whole cross section. The test results indicate that the deformation behavior of the specimens is substantially influenced by the loading conditions, however, the loading conditions only make a little influence on the ultimate carrying capacity. Whatever the loading condition is, the LACFST stub columns can deform plastically with great remaining carrying capacity.
