地震作用下,框架的梁柱节点,受力很大。节点必须有足够的强度和刚度外,柱子的抗弯强度也是很重要的。为了摸索柱和梁不同强度比的梁柱节点,在模拟地震荷载下情况如何,做了8个试验进行检验。一、试件制作 8个全部现浇的框架中节点,参数一般常用的框架尺寸做成1/2足尺比例的试件。
Under the action of earthquakes, the beam-column joints of the frame are subject to great force. The joint must have sufficient strength and stiffness, and the column’s bending strength is also important. In order to explore the beam-column joints with different strength ratios of columns and beams, eight tests were conducted to test the situation under simulated seismic loads. First, the test piece production 8 all in-situ frame of the node, the parameter commonly used frame size made 1/2 full-scale ratio of the test piece.
