The design of new bridges involves the application of current aesthetic principles and the latest engineering tools to create a new structure. Bridge rehabilitation, on the other hand, takes the bridge as it is, warts and all, and tries to bring it back to health. The science of bridge rehabilitation includes load assessment and structural and member analysis. The art of bridge rehabilitation includes the condition assessment and the judgement needed to determine the most appropriate treatment required. Usually, the bridge rehabilitation engineer is faced with a number of options and a balance has to be reached between the extent and cost of repair work, and the estimated remaining life of the repaired structure. Rehabilitation engineers try to account for this by using fairly subjective, life cycle cost analysis techniques. Often, however rehabilitation decisions are based on factors other than engineering ones. Intuition, which Winston Churchill called 'logic in a hurry', and experience usuallu play a major role in the art of bridge rehabilitation. This paper describes a bridge rehabilitation project in the Canadian Prairies, where the extreme climate plays an important part in the design and construction of bridges. It outlines the engineering steps followed in assessing the strength of the bridge and the strengthening measures adopted. It shows how bridge rehabilitation engineers are constantly searching for new ways to meet the challenge of bridge care, and introduces the carbon fiber reinforced polymer (CFRP) strips as a method of deck strengthening.","PeriodicalId":68258,"journal":{"name":"玻璃钢","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"1999-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84373886","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}

These research activities have been accelerated since the Hanshin-Awajii Earthquake, 1995 becasue this retrofitting technique has an advantage due to lightweight, flexibility, non-welding, and easy handling in construction works. The most preferable retrofitting technique for the existing building being in use is jacketing RC columns with carbon or aramid fiber sheets because of the advantage above. Recently many results of the research on short column with spandral wall, columns with wing wall, beams with slab (T shaped beam), earthquake resisting wall have been reported in Japan. This paper introduces, first of all, these experimental research results in detail and the seismic retrofitting effects by the continuous fiber sheets are comprehensively evaluated. Flexural capacity, shear capacity and the improvement of ductility are discussed to evaluate the effect of reinforcement of continuous fiber sheets. Then, methods for evaluating the seismic retrofit of regular columns with continuous fiber sheets are described. A basic idea of the evaluation method proposed for a regular column is shown, and the problems which should be examined are extracted and explained about these effects. As the summary, the problems which should be solved, research direction and prospect are pointed out for the future research on seismic retrofit by continuous fiber sheets. Research needs for establishment of a design method when various members are reinforced by continuous fiber sheets in the future are also discussed.","PeriodicalId":68258,"journal":{"name":"玻璃钢","volume":"30 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"1999-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77022865","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}

In particular tendons with a surface structure that produce significant mechanical interlocking with the adjacent concrete are considered. This type of mechanical interaction can produce damage in the adjacent concrete and within the surface structure of the reinforcing element. The combination of these mechanisms is characterized with an elastoplasticity model that fully couples the longitudinal and radial response; the model calibration is based upon a series of bond tests under differing stress states. The model does not provide a detailed description of the underlying mechanics associated with the progressive bond failure, and it will generally require recalibration when applied for a GFRP bar, the model gives acceptable estimates of the bond strength of several tests of a particular CFRP tendon, even though the specimens have significantly different attributes. Additional validation tests (using data with measures of the experimental scatter) are needed to define the predictive limits of the model; nonetheless the transfer length problem further demonstrates the potential application of the model to help predict and understand the behavior of FRP-reinforced structural components.","PeriodicalId":68258,"journal":{"name":"玻璃钢","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"1999-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87501665","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}

Also, these reinforcements are difficult to evaluate by the fire test methods currently practiced in Japan (2) Safety factors according to members and durability, which are necessary for determining the design strength of continuous fiber bars, are not known, and no performance evaluation methods have been established. The Architectural Institute of Japan (AIJ), Japan Society of Civil Engineers (JSCE) and other institutions proposed about ten test methods for evaluating continuous fiber bars. However, the deteriorating external forces are not known yet in regard to durability, and few reports have been made regarding fire resistance. This paper reports on the commercial use of continuous fiber bars for load-bearing members related to performance evaluation methods and standards on the basis of the proposed standard test methods and state-of-the-art technology on their durability and fire resistance.","PeriodicalId":68258,"journal":{"name":"玻璃钢","volume":"48 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"1999-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88377386","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}
