Three different types of retrofits were carried out: (1) repair and strengthening of cracked precast prestressed concrete (PC) girders, (2) the repair and retrofit of damaged reinforced concrete pedestals, and (3) the repair of a damaged reinforced concrete pier column. The precast PC girders were wrapped with CFRP fabric at the cracked locations to prevent or limit excessive displacements in both the vertical and horizontal directions. The bearing pedestals as well as the pier column have been repaired and wrapped with CFRP fabric to increase their capacity. Instrumentation and remote monitoring of the PC girders made it possible to reduce the cost of the repair by using a more economical repair scheme. 000002103 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000002103 653__ $$abridge strengthening, Carbon Fiber Reinforced Polymer (CFRP), shrinkage crack, bearing pedestal, column repair 000002103 7112_ $$aFirst International Conference on Concrete Sustainability$$cTokyo (JP)$$d2013-05-27 / 2013-05-29$$gICCS13 000002103 720__ $$aPEIRIS, Abheetha$$iCHOO, Ching Chiaw$$iHARIK, Issam E. 000002103 8560_ $$ffischerc@itam.cas.cz 000002103 8564_ $$s1405915$$uhttp://invenio.itam.cas.cz/record/2103/files/S1-8-4.pdf$$y Original version of the author's contribution as presented on CD, . 000002103 962__ $$r2053 000002103 980__ $$aPAPER
