There is an excessive demand for the rehabilitation of frame-type RC buildings which do not satisfy current seismic code provisions. Therefore, it is imperative to develop user-friendly strengthening methodologies which do not necessitate the evacuation of the building during rehabilitation period. The aim of this study was to strengthen the masonry infill walls by means of diagonal carbon fiber-reinforced polymer fabrics and to integrate them with the existing structural frame in order to form a new lateral load resisting system. This study investigated the possible effects of height-to-width ratio of the infills on the overall behavior attained by the previously developed rehabilitation methodology. In the first part of the study, eight 1/3 scaled, one-bay, two-story RC frames with two different aspect ratios were tested. The experimental results in terms of lateral stiffness, strength, drift, and energy dissipation characteristics of the specimens were discussed. In the second part, a numerical study of the frames was conducted to estimate the non-linear behavior of the specimens.

Strengthening of brick infilled rc frames with cfrp reinforcement-general principles Akın, Emre; Özcebe, Güney; Department of Civil Engineering (2011) There is an excessive demand for the rehabilitation of frame type reinforced concrete (RC) buildings which do not satisfy current earthquake code provisions. Therefore, it is imperative to develop user-friendly seismic strengthening methodologies which do not necessitate the evacuation of building during rehabilitation period. In this study, it was aimed to strengthen the brick infill walls by means of diagonal Carbon Fiber-Reinforced Polymer (CFRP) fabrics and to integrate them with the existing structural...
Strengthening of deficient RC frames with high strength concrete panels: an experimental study BARAN, MEHMET; Susoy, Melih; Tankut, Tugrul (2011-01-25) An economic, structurally effective and practically applicable strengthening technique was developed for reinforced concrete (RC) framed buildings. The idea of the technique is to convert the existing hollow brick infill wall into a load carrying system acting as a cast-in-place RC infill wall by bonding relatively thin high strength precast concrete PC panels to the plastered hollow brick infill. For this purpose, a total of eight one-third scale, one bay, one story frames were tested under reversed-cyclic...
Retrofit of Non-Ductile RC Frames with Precast Concrete (PC) Wall Panels BARAN, MEHMET; Tankut, Tugrul (2011-12-01) An economic, structurally effective and practically applicable strengthening method had been developed for reinforced concrete (RC) framed buildings. This study presents the test results on strengthening of deficient RC frames by using high strength precast concrete (PC) panels. The idea of the method is to convert the existing hollow brick infill wall into a load carrying system by bonding PC panels on to the plastered hollow brick infills. For this purpose, six (two reference and four strengthened) one-th...
Use of steel fiber reinforced mortar for seismic strengthening Sevil, Tugce; BARAN, MEHMET; Bilir, Turhan; Canbay, Erdem (2011-02-01) The objective of this research was to develop an economical, structurally effective, and practically applicable steel fiber reinforced mortar (SFRM) which could be applied onto the hollow brick infills of a reinforced concrete (RC) structure. Masonry walls were almost converted into strong and rigid infills with the application of SFRM. Two different mix proportions were produced with the composition of Portland cement, fine aggregate, water, and plasticizer or bonding agent as the chemical admixture. Tests...
Modelling effects of insufficient lap splices on a deficient reinforced concrete frame Lin, Wesley Wei -Chih; Sucuoğlu, Haluk; Binici, Barış; Department of Earthquake Engineering and Engineering Seismology (2013) In order to reduce seismic risk in vulnerable buildings, buildings identified to be at risk should be assessed and strengthened. Performance evaluation of deficient buildings has become a major concern due to devastating earthquakes in the past. In order to justify new provisions in design and assessment codes, experiments and analyses are inherently necessary. In this thesis study, investigations into the behaviour of two deficient reinforced concrete frames built at Middle East Technical University’s Str...
