摘要:
在嵌入式连接件的基础上，提出一种带翼缘板嵌入式连接件，依据实际工程，进行８ 个试件的推出试验，分析其在不同阶段的荷载⁃滑移曲线关系，研究抗剪承载力的影响因素及破坏模式。 结果表明：在钢翼缘板宽厚比满足一定条件时，混凝土板厚处裂缝为直线，板宽处裂缝为波纹线；当钢翼缘板宽厚比未满足条件时，翼缘板发生失稳现象，混凝土裂缝未充分发展，加载因翼缘板失稳无法继续，试验提前结束。翼缘板未失稳试件抗剪承载力约为现有嵌入式连接件承载力理论计算值的15倍，证明较嵌入式连接件，翼缘板明显提高了该新型连接件的抗剪承载力。
Abstract:
On the basis of embedded connectors, a kind of embedded connectors with flanges is proposed. According to the actual engineering, push-out tests of 8 specimens are carried out, and the relationship between load-slip curves at different stages is analyzed, and the shear resistance is studied. Influencing factors and failure modes of bearing capacity. The results show that: when the width-thickness ratio of the steel flange plate meets certain conditions, the cracks at the thick part of the concrete slab are straight lines, and the cracks at the width of the slab are corrugated lines; , the concrete cracks were not fully developed, and the loading could not continue due to the instability of the flange plate, so the test ended early. The shear bearing capacity of the unbending specimen of the flange plate is about 1.5 times of the theoretical calculation value of the bearing capacity of the existing embedded connector, which proves that the flange plate significantly improves the resistance of the new connector compared with the embedded connector. shear capacity.
