给出了8个梁-柱、梁-梁外伸端板螺栓连接试样的试验结果,其中4个连接件在外伸端板处使用了加劲肋。将低阻力螺栓受拉区和受压区的失效模式进行对比,基于整体弯矩-转角曲线和螺栓拉应力的发展对试验结果进行分析。试验主要关注失效模式、阻力发展、刚度及扭转能力。将试验结果与按照EC3提供的方法得到的分析结果进行对比,评估该分析方法(包括分析外伸端板处使用了加劲肋的连接件)的准确性。
The experimental results of eight bolted specimens of beam-column, beam-beam outrigger were given, of which four were using stiffeners at the outrigger end plate. The failure modes of tension zone and compression zone of low resistance bolt are compared, and the test results are analyzed based on the development of integral bending moment - rotation curve and bolt tensile stress. The test focuses on failure modes, resistance development, stiffness and torsional ability. The test results were compared to those obtained according to the methods provided in EC3 and the accuracy of the analytical method, including the analysis of stiffeners used at outrigger ends, was evaluated.
