摘要
通过 2个仅核芯区配箍不同的钢管高强混凝土叠合柱 -混凝土梁节点往复加载试验 ,研究了叠合柱核芯区的抗剪性能。结果表明 ,由于小钢管和钢翅片的作用 ,剪切破坏的核芯区仍有良好的耗能能力和变形能力。对其中一个核芯区箍筋加密的试件进行了非线性有限元分析 。
Two RC beam\|steel tube fill high strength concrete composite column joints were tested under cyclic loading for studying the shear behavior of its core. The only difference of the two joints is the number of horizontal stirrup in the core. The test results show that because of the contribution of small size steel tube and steel plates, the core has excellent energy\|dissipation capacity and deformation capacity even it was in shear failure. The specimen with fortified stirrups in the core is analyzed by nonlinear FEA. A shear strength formula and design recommendations for the composite column joint core are presented.
