【摘要】：为了分析不同削弱参数对翼缘开孔削弱型节点抗震性能的影响,应用ANSYS有限元软件,将不同削弱参数的翼缘开孔削弱型节点和未开孔普通节点进行对比分析,研究了翼缘开孔削弱型节点在不同削弱参数下的骨架曲线、极限承载力、延性和耗能能力。结果表明:相比未开孔普通节点,削弱参数在合理范围内取值,可以使翼缘开孔削弱型节点的耗能能力有较大提高,使抗震性能得到明显改善,同时保证极限承载力和延性只有较小程度的下降。
[Abstract]:In order to analyze the effect of different weakening parameters on the seismic behavior of flange open-hole weakened joints, the ANSYS finite element software is used to compare and analyze the flange open-hole weakened joints with different weakening parameters. The skeleton curve, ultimate bearing capacity, ductility and energy dissipation capacity of flange perforated weakened joints under different weakening parameters are studied. The results show that compared with the common joints with no openings, the energy dissipation capacity of the flange open hole weakened joint can be greatly improved and the seismic performance can be obviously improved by selecting the values of the weakening parameters within a reasonable range. At the same time, the ultimate bearing capacity and ductility are reduced only to a lesser extent.
