摘要:
为研究节段料石拼接构造对内填料石钢管混凝土(SCFST)柱抗震性能的影响,通过ABAQUS软件建立SCFST柱的数值模型。以轴压比、钢管厚度、料石尺寸、节段料石构造为变化参数,对12个试件进行低周反复荷载作用下的数值模拟。结果表明:内填料石可显著提高试件的初始刚度、承载力及耗能能力,但会导致试件延性系数降低;混凝土强度、轴压比对试件的初始刚度、峰值承载力及耗能能力影响不明显,但对延性系数影响较大;随着料石尺寸的增大,初始刚度基本不变,峰值承载力最多降低17.8%,试件延性系数略微降低,耗能能力显著提高;料石节段布置与料石整体布置试件的初始刚度、峰值承载力基本相当,但延性系数最多降低32.7%,且料石节段间填充混凝土拼接时可显著提高试件承载力。
Abstract:
To study the effect of segment stone splicing structure on the seismic performance of stone prism encased concrete filled steel tube(SCFST)columns, a numerical model of SCFST columns is established by ABAQUS software. Numerical simulation is conducted on 12 specimens under low cyclic loading under different parameters, such as axial compression ratio, steel tube thickness, stone size and segment stone structure. The results show that the internal packing stone can significantly improve the specimen’s initial stiffness, bearing capacity and energy dissipation capacity, but reduce the specimen’s ductility coefficient. The effects of concrete strength and axial compression ratio on initial stiffness, peak bearing capacity and energy dissipation capacity are not apparent, but significantly affect the ductility coefficient. With the increase of stone size, the initial stiffness is basically unchanged, the peak bearing capacity decreases by 17.8% at most, the ductility coefficient of the specimen decreases slightly, the energy dissipation capacity increases significantly. The initial stiffness and peak bearing capacity of the specimens arranged in stone segments are the same as that arranged in stone as a whole, but the ductility coefficient can be decreased 32.7% at most, the bearing capacity of the specimens increases significantlyd when the concrete is filled between the stone segments.
