Five two-span reinforced concrete beams with \"T\" cross sections were tested. Four different strengthening systems were examined. Two beams were strengthened with two different types of carbon fiber reinforced polymer (CFRP)sheets. The first beam was strengthened for flexure only while the second beam was strengthened for both flexure and shear. The third beam was strengthened for flexure only while the second beam was strengthened for both flexure and shear. The third beam was strengthened with glass fiber reinforced polymer (GFRP) sheets, while CFRP plates were used in strengthening the fourth beam. The fifth beam was a control. Each beam was loaded and unloaded for at least one cycle of loading before failure. The effects of FRP strengthening on failure modes, load capacity, cracking pattern and propagation, and deflections are presented. It was concluded that the use of FRP laminates to strengthen continuous beams is effective in reducing deflections and increasing their load carrying capacity. Furthermore, beams strengthened with FRP laminates exhibit smaller and better-distributed cracks.","PeriodicalId":68258,"journal":{"name":"玻璃钢","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"1999-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83786696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Joffre bridge, located over the St-Francois River in Sherbrooke, Quebec, Canada, consists of five longitudinal spans with length varying from 26 to 37 meters. This spacing constitutes the highest span using FRP reinforcement. A part of the concrete deck slab (7.3 m x 11.5 m) and a portion of the traffic barrier and the sidewalk was reinforced with Carbon and Glass Fiber Reinforced Polymer (FRP) reinforcement. In addition, four FRP reinforced full-scale one-way concrete slabs were laboratory tested under static and cyclic loading, in order to optimize the design process. The bridge was extensively instrumented with different types of sensors, including integrated fiber optic sensors in FRP reinforcement that were integrated into the FRP reinforcement. The results of the laboratory study, in terms of deflection and crack-width versus applied load, as well as the results of calibrated loads, using heavy trucks, are also presented in this paper.","PeriodicalId":68258,"journal":{"name":"玻璃钢","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"1999-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91038851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The specimens were RC beams with several conditions of CFRP sheet separation at bending span and strengthening methods by CFRP sheet at anchorage. The bending test of RC beams and the adhesion test of CFRP sheet were performed. The strength of RC beam was improved by CFRP sheet strengthening in comparison with conventional RC beam and estimated by existing methods. The adhesive strength between CFRP sheet and concrete at the anchorage zone were 1.12-2.53 MPa, which were the same value as tensile concrete strength and enough. When separation occurred between CFRP sheet and concrete at bending span of RC beams, the flexural behavior of RC beams, especially about strain or stress distribution of CFRP sheet, was influenced by methods of anchorage and characteristic property of concrete at the anchorage zone. And it was confirmed no effects of preventing the progress of crack in this case. We could say that it was necessary to pay attention in case of using CFRP sheet for repairing RC member deterioration by rebar corrosion or crack.","PeriodicalId":68258,"journal":{"name":"玻璃钢","volume":"56 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"1999-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79742985","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
