Use of CFRP to Provide Continuity in Reinforced Concrete Members

Описание:
A special problem in many reinforced concrete (RC) structures built in the 1970’s and earlier is the lack of continuity between elements. Continuity is a characteristic of structures essential to preventing collapse. Therefore, in extreme loading conditions such as loss of a column support due to terrorist attack or if earthquake or other extreme actions occur, the structures could be vulnerable to collapse. The study reported here focused on two structural discontinuities in existing RC structures, discontinuity in bottom reinforcement in beams (horizontal discontinuity) and poorly detailed lap splices in columns (vertical discontinuity). The objective of this study was to develop rehabilitation methods using Carbon Fiber Reinforced Polymer (CFRP) to provide continuity of reinforcement. Two separate experimental studies were conducted. The test results indicated that continuity could be provided through the CFRP rehabilitation. Based on the test results, designguidelines for the...Похожие книги
