Joint for improving progressive collapse resistance of frame
The invention provides a joint for improving progressive collapse resistance of a frame, and relates to the field of building structures. The joint comprises a frame column, frame beams, connecting plates and bent steel bar s, wherein one ends of the frame beams are fixedly connected with the flanges of the frame column, the connecting plates are fixedly connected with web plates of the frame beams, one ends of the bent steel bars are fixedly connected with the flanges of the frame column, and the other ends of the bent steel bars are fixedly connected with the connecting plates. The joint has the advantages that when the frame structure deforms greatly, the bent steel bars are straightened to provide axial tension, and a force transmission path can be replaced at the joint, so that a second defense line is provided for the frame structure to resist progressive collapse.
本发明提供一种提高框架抗连续倒塌能力的节点，涉及建筑结构领域；包括：框架柱；框架梁，所述框架梁的一端与所述框架柱的翼缘固定连接；连接板，与所述框架梁的腹板固定连接；弯折钢筋，所述弯折钢筋的一端与所述框架柱的翼缘固定连接，所述弯折钢筋的另一端与所述连接板固定连接。本发明的优点在于：当框架结构发生大变形时，弯折钢筋被拉直提供轴向拉力，实现节点处可替代传力路径从而为框架结构抵抗连续倒塌提供第二道防线。
