施工误差对框架节点抗震性能影响研究

In the modern high-rise building structure, reinforced concrete frame structure wide application. Frame joint as an important part of the frame structure of the aseismic performance influence. In this paper, through three reinforced concrete beam-column joints test, based on strength, ductility and energy dissipation situation, study the construction error influence on the seismic behavior of the beam-column joints, The results show that the construction error on the seismic performance of frame has a certain impact, the positive error samples is superior to the negative error sample in the carrying capacity, but the negative error sample is better than the positive error samples in the ductility and energy dissipation situation.
