摘要
该文就自密实混凝土技术融入钢纤维后能有效提升结构抗剪承载能力、屈服后变形能力和耗能能力的研究成果出发,从材料配合比优化、施工模具加固、施工混凝土泵送等方面对其进一步研究,解决了钢纤维对自密实混凝土流动性的不利影响和混凝土制备过程中材料本地化等问题,可使建筑结构获得更好的抗裂性和抗震性能。
Based on the research results that the integration o f steel f ib e r to the self-compact concrete can e ffe c tively improve the anti-shear load-carryingcapacity, the deformation capacity and energy dissipation capacity o f the structure after y ie ld, th is paper further studies the optim ization o f materials＇ m ixproportion, reinforcement of construction mold, pumping o f construction concrete, etc., solving the adverse effects o f steel f ib e r on the m o b i l ity o f the self-compact concrete, the material lo ca liza tio n in the concrete preparation and other issues, which help the b u ild in g structure aquire better crack resis-tance and seismic performance.
