Self-resetting composite energy dissipation type beam column connecting piece and construction method thereof
The invention discloses a self-resetting composite energy dissipation type beam column connecting piece which is arranged at the joint of a prefabricated column and a prefabricated beam and comprises a column side end plate, a beam side end plate, two friction energy dissipation pieces and two U-shaped energy dissipation pieces. The column side end plate is fixedly arranged at the beam-column connecting position of the prefabricated column. The beam side end plate is fixedly arranged at the beam-column connecting position on the precast beam; the two friction energy dissipation pieces are arranged in the middle of the whole beam-column connecting piece after being connected through a bearing in a penetrating manner, and are fixedly connected with the column side end plate and the beam side end plate; the two U-shaped energy dissipation pieces are symmetrically arranged above and below the friction energy dissipation piece and fixedly connected with the column side end plate and the beam side end plate. Wherein an opening of the U-shaped energy consumption piece located on the upper portion faces downwards, and an opening of the U-shaped energy consumption piece located on the lower portion faces upwards. The friction energy dissipation piece and the U-shaped energy dissipation piece form an artificial plastic hinge together, so that the self-resetting composite energy dissipation type beam column connecting piece is achieved. The connecting piece is reliable in framework, excellent in anti-seismic performance and high in recoverability after an earthquake.
本发明公开了一种自复位复合耗能型梁柱连接件，设置在预制柱和预制梁的连接处，包括柱侧端板、梁侧端板、两个摩擦耗能件以及两个U型耗能件；柱侧端板固定设置在预制柱上的梁柱连接位置处；梁侧端板固定设置在预制梁上的梁柱连接位置处；两个摩擦耗能件通过轴承贯通连接后，设置在整个梁柱连接件的中间位置，并与柱侧端板和梁侧端板固定连接；两个U型耗能件对称设置在摩擦耗能件的上方和下方，并与柱侧端板和梁侧端板固定连接；其中，位于上方的U型耗能件开口向下，位于下方的U型耗能件开口向上；摩擦耗能件与U型耗能件一起形成人工塑性铰，以实现自复位复合耗能型梁柱连接件。该连接件架构可靠，抗震性能优异，震后可恢复性强。
