Method for improving anti-seismic property of concrete special-shaped column frame node core area
The invention belongs to the technical field of constructional engineering, and particularly discloses a method for improving the anti-seismic property of a concrete special-shaped column frame node core area, which comprises a frame node, a frame column, a frame beam and an infilled wall used in the method; the frame joint comprises a special-shaped column frame beam-column joint and an expanded reinforcing region; horizontal stirrups and vertical stirrups are configured in the expanded reinforcing area, form longitudinal and transverse grids and are tied and fixed by horizontal tie bars; the expanded reinforcing area is equal to the frame columns, the frame beams and the infilled wall in thickness; according to the method, the expanded energy-saving area is enclosed and reinforced by adding the expanded reinforcing area and adding the horizontal stirrups and the vertical stirrups, so that the constraint effect on the node area can be enhanced, the stress level of the node area is reduced, and the anti-seismic property of the node area is improved; the bearing capacity and the deformation capacity of all the components can be better exerted by strengthening the bearing capacity of node connection, and therefore the overall anti-seismic performance of the special-shaped column frame structure is improved.
本发明属于建筑工程技术领域，具体公开了一种提高混凝土异型柱框架节点核心区抗震性能的方法，包括做法中用到的框架节点、框架柱、框架梁以及填充墙；框架节点包括异型柱框架梁柱节点和扩大加强域；扩大加强域中配置有水平箍筋和竖向箍筋，水平箍筋和竖向箍筋形成纵横网格，并由水平拉结筋拉结固定；扩大加强域与框架柱、框架梁以及填充墙均等厚；本发明中通过增设扩大加强域的方法，并附加水平箍筋和竖向箍筋对扩大的节能域进行围合加强，能够加强对节点域的约束作用，降低了节点域的应力水平，提高了节点域的抗震性能；通过加强节点连接的承载力，更能发挥各构件的承载力和变形能力，从而提高了异型柱框架结构的整体抗震性能。
