| 中文摘要 | 针对钢筋混凝土构件正截面受弯承载力,从结构设计方法、材料强度取值、正截面承载力计算方法、最大和最小配筋率、受弯承载力计算结果,对我国《混凝土结构设计规范》(GB 50010-2002)和美国ACI 318M-05规范进行了较为全面的对比分析。结果表明,在适筋范围,两国规范的受弯承载力的安全储备程度基本相近,但在趋向超筋梁时,我国规范的安全储备小于美国规范;美国规范对超筋梁的限制比我国规范要严,最小配筋率比我国规范高约1.5倍。此外,美国规范采用的基于概率理论的荷载抗力系数设计法,在调整不同受力性能构件的安全储备方面更为灵活。; A comparison of flexure strengths of RC beams is carefully studied between Chinese and ACI 318M-05 design codes,including design methods,concrete strengths,calculation methods,maximum and minimum ratios of reinforcement and calculation results.The results show that the strength reduction factors are almost the same between the both codes,but the requirement of the maximum ratio of reinforcement of ACI318 code is stricter than Chinese code,while the minimum ratio of reinforcement of ACI318 code is 50% larger than Chinese code.Furthermore,the load-resistance coefficient design method of ACI 318 code seems more flexible in adjusting the design safety degree for different behaviors of RC elements subjected to various forces. |
