碳纤维片材粘贴加固RC板桥计算方法研究
|
摘要
随着交通运输的发展和通行荷载等级的提高,大量现役桥梁需要进行承载力提升和维修加固。钢筋混凝土板桥因其独有的优点,在高速公路小跨径桥梁中被大量的采用。已有试验和工程应用研究可以看出,碳纤维片材加固矩形截面实心板和T梁研究得较多,对碳纤维片材用于空心板梁的加固比较少。截至目前为止我国公路行业中尚无这一专业工作的技术规范,亦无暂行技术规程。因此,有待于进一步完善和总结计算理论和方法。
本文收集国内外有关粘贴碳纤维加固设计的计算方法,收集到国内外有关公路桥梁及相关行业的加固规程、规范中的计算方法和公式,主要有《碳纤维片材加固混凝土结构技术规程》中国工程建设标准化协会标准、《混凝土结构加固设计规范》中华人民共和国国家标准、我国台湾规范、美国ACI-440规程等、另外还有一些论文所提出的计算公式。考虑我国各设计、科研及施工单位在桥梁加固工作中已有的成果及所借鉴使用的规范、标准,确定了《碳纤维片材加固混凝土结构技术规程》、《混凝土结构加固设计规范》和台湾规范这三种规范中的碳纤维粘贴加固计算公式进行对比分析。结合文献中已有的试验及数据,分别应用三种计算公式对所取试验板进行加固计算,并对试验值和计算值进行对比和误差分析,经比较推荐《混凝土结构加固设计规范》中的计算公式作为板桥加固计算的依据,并通过计算实例进行验证。
Along with the transportation development and thel load rank enhancement, the massive bridges need to carry on the carrying capacity promotion and the reinforcement. Because of the merit of the RC slab bridge, in highway small span bridges it is used massively. Had experimental and the project applied research may see, the solid slad bridge and T-beam bridge strengthening with CFRP have been studied much as well as the hollow slab bridges strengthening with CFRP had been studied little. Up to now there did not have the technical standard of this specialized work in road profession in our country, also not the temporary technical regulations. Therefore, waits for further consummates and the summary computation theory and the method.
This article collect the design calculation methods strengthening with CFRP from both at home and abroad, collects the domestic and foreign related highway bridge and in the correlation profession reinforcement regulations, the standard computational method and the formula, mainly has "Technical specification for strengthening concrete structures with carbon fiber reinforced reinforced polymer laminate"、"Design code for strengthening concrete structure"、our country Taiwan standard、the American ACI-440 regulations、English Design guidance for strengthening concrete structures、using fibre composite materials, the Japanese carbon textile fiber cloth glue labor law and so on. Considered the standard, the standard which our country each design, the scientific research and the construction which h'ad the achievement and profit from in the bridge reinforcement work, had determined " Technical specification for strengthening concrete structures with carbon fiber reinforced reinforced polymer laminate "," Design code for strengthening concrete structure "and the Taiwan standard carries on the contrast analysis.In the union literature had the experiment and the data, apply three kind of formulas to take the experimental board separately to carry on the reinforcement computation, and to experiments the value and the predicted value carries on the contrast and the error analysis, recommends " Design code for strengthening concrete structure" after the comparison the formula to take the plank bridge reinforcement computation the basis, and carries on the confirmation through the computation example.
