Anti-seismic and anti-progressive-collapse frame structure based on UHPC
The invention discloses an anti-seismic and anti-progressive-collapse frame structure based on UHPC. The anti-seismic and anti-progressive-collapse frame structure comprises a plurality of precast concrete columns, a plurality of reserved channels, a plurality of precast concrete superposed beams, a plurality of beam bottom longitudinal bars, a plurality of beam stirrups, a plurality of beam top longitudinal bars, a plurality of lap joint steel bars, a plurality of post-pouring superposed layers and a plurality of post-pouring UHPC areas; and the precast concrete columns and the precast concrete superposed beams are connected through the post-pouring UHPC areas, the beam top longitudinal bars penetrate through the reserved channels, the post-pouring superposed layers and the post-pouring UHPC areas, the lap joint steel bars penetrate through the reserved channels and the post-pouring UHPC areas, and the beam bottom longitudinal bars and the lap joint steel bars are connected in the post-pouring UHPC areas in a lap joint mode. The UHPC is used in a main stress area of the frame structure, the excellent compression resisting, tensile, bonding and energy dissipation capacity of the UHPC are flexibly applied to the structure, the assembled concrete frame structure form is innovated, and meanwhile the anti-seismic property and the anti-progressive-collapse property of the structureare improved.
本发明公开了一种基于UHPC的抗震与抗连续倒塌框架结构，包括多个预制混凝土柱、多个预留通道、多个预制混凝土叠合梁、多根梁底纵筋、多根梁箍筋、多根梁顶纵筋、多个搭接钢筋、多个后浇叠合层、和多个后浇UHPC区域，预制混凝土柱和预制混凝土叠合梁之间通过后浇UHPC区域连接，梁顶纵筋穿过预留通道、后浇叠合层和后浇UHPC区域，搭接钢筋穿过预留通道和后浇UHPC区域，梁底纵筋与搭接钢筋在后浇UHPC区域搭接连接。本发明在框架结构的主要受力区域使用UHPC，将UHPC优秀的抗压、抗拉、粘结和耗能能力灵活的运用在结构上，创新装配式混凝土框架结构形式，同时提高了结构的抗震性能和抗连续倒塌性能。
