【摘要】 将超高性能混凝土(UHPC)用于钢筋混凝土构件的永久模板,形成高耐久新型组合结构,是可持续结构的重要发展方向之一。为了考察U型UHPC永久模板对钢筋混凝土梁抗弯性能的影响,本文开展了具有U型UHPC永久模板的钢筋混凝土组合梁的大比例尺抗弯性能试验,同时开展了普通钢筋混凝土梁的受弯对比试验;分析了该U型UHPC永久模板对钢筋混凝土梁初裂性能、极限抗弯承载力的影响。本文的研究工作可为可持续新型UHPC-RC组合梁的抗弯设计提供科学参考。更多还原

【Abstract】 New composite structure with high durability can be obtained by combination of reinforcement concrete(RC)and Ultra high performance concrete(UHPC) as permanent form of RC,which is one of the important directions of the sustainable structure.In order to investigate the effects of U shape UHPC permanent form on the flexural behaviors of RC beam,a full scale flexural test ofUHPC-RC compos ie beam win U shape UHPC permanent form are carried out in this paper,and a reference flexural test of normal RC beam is tested simultaneously.The effects of U shape UHPC permanent form on the initial cracking behavior and ultimate flexural bearing capacity of RC beam are analyzed.The research may provide a reference for the flexural design of this new sustainable UHPC-RC composite beam.更多还原
