Laminated stirrup and method for improving ductility of frame column
The invention discloses a laminated stirrup and method for improving the ductility of a frame column. An additional closed stirrup is added on the adjacent side of the first closed stirrup of the dense area stirrups of the frame column in parallel; the hook position of the additional closed stirrup and the hook position of the first closed stirrup are arranged diagonally; the two stirrups are bound and overlapped together to form an overlapped stirrup structure; the additional closed stirrup is only required to be placed close to the first stirrup at the end part of the frame column to form the overlapped stirrup, and the placement direction of the additional closed stirrup enables the hooks of the two stirrups to be positioned at opposite positions. The construction process is simple and convenient. After the first stirrup at the end part of the frame column is changed into the overlapped stirrup, the overlapped stirrup does not form a weak position at the hook position like a single stirrup. Under the action of load, the hook of the first overlapped stirrup with the largest stress at the end of the frame column is not prone to disengagement, the transverse restraining effect of the closed stirrups on the longitudinal bars and the concrete is fully exerted, and the ductility and the anti-seismic property of the frame column are improved.
本发明公开了一种提高框架柱延性的叠合箍筋与方法；在框架柱的加密区箍筋的第一个封闭箍筋的邻侧并列增加一个附加封闭箍筋；该附加封闭箍筋的弯钩位置与第一个封闭箍筋的弯钩位置呈对角布置；并将两者绑扎叠合在一起，形成叠合箍筋结构；仅需紧挨着框架柱端部的第一个箍筋，放置一个附加封闭箍筋形成叠合箍筋，附加封闭箍筋放置方向应使得两箍筋的弯钩处于相对位置。施工工艺简单方便。框架柱端部的第一个箍筋变成了叠合箍筋后，叠合箍筋并不会像单个箍筋一样在弯钩处形成薄弱位置。在荷载作用下，框架柱端部受力最大的第一个叠合箍筋的弯钩不易脱开，充分发挥了封闭箍筋对纵筋和混凝土的横向约束作用，提高了框架柱的延性和抗震性能。
