摘要
本文主要介绍了所开展的梁柱组合节点的拟动力试验,梁柱连接采用高强度螺栓平端板形式。试验采用经过调幅的具有不同地震加速度峰值的Ispara地震动作为激励进行加载,对试件在地震作用下的加速度反应、位移反应、滞回性能、刚度和耗能进行分析,对试验现象和结果进行了比较详细的阐述和分析。
This paper is concerned with the tests on composite beam-to-column joints subject to low cyclic loads. The beam-to-column steelwork connections were made of bolted flush end plate. The specimen was subjected to nine tests of increasing magnitude based on the Ispara ground motion. Dynamic responses including acceleration,displacement, varying stiffness, hysteretic behavior and energy dissipation corresponding to input excitation are discussed. Detailed test observations and results were reported.
