摘要
为了研究不同约束机理的配钢形式对钢与混凝土组合异形柱-钢梁空间中节点抗震性能的影响,设计了4个型钢混凝土异形柱-钢梁空间中节点,并对其进行了低周反复加载试验,在联合钢管混凝土异形柱-钢梁空间中节点抗震性能成果的基础上,对比分析了相关节点在破坏形态、滞回曲线、耗能能力及变形性能方面的差异。研究结果表明:配型钢的空间中节点主要发生剪切斜压破坏,同时具有黏结裂缝的破坏形态,而配钢管的空间中节点则发生了核心区的剪切破坏;钢管节点试件的标准化滞回曲线包围了型钢节点试件,且其抗剪承载能力更好、初始刚度和耗能能力更大,但延性性能没有足够的优势。
In order to research the influence of steel forms with different constraint mechanisms on the seismic behavior of spacial interior joints composed of steel and concrete composite special-shaped column and steel beams,four spacial interior joint specimens with SRC special-shaped column and steel beams are designed to test under low frequency cyclic loading. At the same time,the existing spacial interior joints composed of CFST special-shaped column and steel beams in seismic performance test are collected in this paper. Failure modes,standardized hysteresis curves,energy dissipation capacity and ductility coefficient of correlative joints are contrastively analyzed. The results show that the failure mode of spacial interior joints with steel shape is the baroclinic shear bond failure,while the failure mode of spacial interior joints with steel tube is the shear failure. The standardized hysteresis curves of interior joints with steel shape are surrounded by the interior joints with steel tube. The shear bearing capacity,initial stiffness and energy-dissipating capacity of spacial interior joints composed of CFST special-shaped column and steel beams are greater than those of the joints composed of SRC special-shaped column and steel beams,but the ductility performance of the former do not have enough advantage.
