全焊接组合梁–柱节点承载力试验研究

Abstract

为了研究全焊接组合梁–柱节点的承载力，通过两个中跨全焊接组合梁–柱节点在单调静力作用下和低周往复荷载作用下的破坏试验，获得了节点承载性能、滞回性能和破坏模式。由试验结果可看出：节点主要的破坏模式为钢梁下翼缘及腹板局部屈曲和混凝土压溃。本文将介绍主要试验结果，为后续试验研究提供依据。 An experimental research on load bearing capacity of joints for composite beam to column was carried out. Two specimens were tested under monotonic static loading and cyclic loading, and the load bearing capacity, cyclic performance and failure mode were derived from the test results. It can be concluded that the major failure mode of the joints is the local buckling of the lower steel beam flange and the crush of the compressed concrete. The experimental results can provide some reference for the following research and experiments.
