摘要
基于钢筋自密实混凝土梁受弯试验,探讨混凝土强度和配筋率对钢筋自密实混凝土梁正截面受弯性能、开裂弯矩和受弯极限承载力的影响;并将试验结果与我国现行《混凝土结构设计规范》(GB 50010—2010)以及相关文献进行比较分析。结果表明:自密实混凝土梁正截面极限承载力高于普通混凝土梁;自密实混凝土开裂弯矩比普通混凝土稍低;随自密实混凝土强度和配筋率的提高,梁极限承载力提高显著。
Based on the flexural experiments on self-compacting concrete beams, the flexural behavior, cracking moment and ultimate bearing capacity were discussed with different concrete strengths and rein- foreement ratios. Experiments results were analyzed and compared with that in code and in other related papers. It was shown that self-compacting concrete beams had stronger ultimate bearing capacity and wea- ker cracking moment compared with normal concrete beams. Its ultimate bearing capacity was improved with the increase of its strength and reinforcement.
