Steel-UHPC composite beam adopting mixed connection of various PBL connecting pieces and design method of steel-UHPC composite beam
The invention discloses a steel-UHPC composite beam adopting various PBL connecting pieces for mixed connection and a design method thereof.The steel-UHPC composite beam comprises UHPC components, an I-shaped steel beam and a plurality of cover beams, the cover beams are arranged below the I-shaped steel beam, the UHPC components are arranged on the I-shaped steel beam, and the UHPC components are arranged on the I-shaped steel beam. A plurality of PBL connecting pieces adopting NPR steel bars are arranged in the sagging moment section of the UHPC component, and a plurality of pulling-resistant non-shearing-resistant PBL connecting pieces are arranged in the hogging moment section of the UHPC component. The PBL connecting piece adopting the NPR steel bars to replace common steel bars is applied to the sagging moment section of the composite structure, the continuation capacity and the bearing capacity of the composite structure are enhanced, and the structural integrity and the structural stability are improved. The tensile stress of the hogging moment section of the combined structure is effectively released, and the using performance, the long-term performance and the durability of the combined structure are remarkably improved.
本发明公开了一种采用多种PBL连接件混合连接的钢‑UHPC组合梁及其设计方法，所述钢‑UHPC组合梁包括UHPC构件、工字钢梁以及多个盖梁，所述盖梁设置在所述工字钢梁的下面，所述UHPC构件设置在所述工字钢梁的上面，所述UHPC构件的正弯矩区段排列设置有多个采用NPR钢筋的PBL连接件，所述UHPC构件的负弯矩区段排列设置有多个抗拔不抗剪PBL连接件。本发明将采用NPR钢筋代替普通钢筋的PBL连接件应用在组合结构正弯矩区段，增强了组合结构的延续能力和承载能力，提高了结构整体性和结构稳定性。本发明有效释放了组合结构负弯矩区段的拉应力，显著提高了组合结构的使用性能、长期性能和耐久性能。
