Anti-seismic strengthening method for reinforced concrete frame joints with stress defects
The invention provides an anti-seismic reinforcing method for reinforced concrete frame joints with stress defects. The anti-seismic reinforcing method comprises the steps that the number of reinforcing steel bars is determined when the reinforcing steel bars of the target specification are adopted as the reinforcing steel bars; first mounting holes and second mounting holes are alternately formed in the node core area in the width direction of the beam; a first channel and a second channel which are respectively communicated with the first mounting hole and the second mounting hole are formed in the lower reinforcing section close to the lower side of the joint core area along the vertical direction; reinforcing steel bars are installed; fRP cloth is annularly wrapped on the lower reinforcing section and the upper reinforcing section close to the upper side of the node core area. According to the embodiment, after the parameters of the reinforcing steel bars are determined, the first mounting holes and the second mounting holes are formed in the joint core area, the first channels and the second channels are formed in the concrete protection layer at the column end, the reinforcing steel bars bent in advance are mounted, and finally the FRP cloth is used for surrounding the upper reinforcing section and the lower reinforcing section; and the shear resistance of the node core area and the bending resistance of the column end are improved.
本发明提供了一种针对带受力缺陷的钢筋混凝土框架节点的抗震加固方法，包括确定采用目标规格钢筋作为加固钢筋时加固钢筋的数量；沿梁的宽度方向在节点核心区交替地开设第一安装孔和第二安装孔；在靠近节点核心区下侧的下加固区段上沿竖直向开设分别与第一安装孔和第二安装孔连通的第一槽道和第二槽道；安装加固钢筋；在下加固区段和靠近节点核心区上侧的上加固区段环包FRP布。该实施方式确定加固钢筋参数后，通过在节点核心区开设第一安装孔和第二安装孔，以及在柱端的混凝土保护层中开设第一槽道和第二槽道，安装预先弯折的加固钢筋，最后使用FRP布对上加固区段和下加固区段环包，提升节点核心区的抗剪性能以及柱端的抗弯性能。
