An innovative non-evacuation retrofitting technique has been developed for RC buildings, which form the major portion of the existing stock in Turkey. The introduction of cast-in-place RC infill walls, connected to existing frame members, is known to be very effective in improving the overall seismic performance. However, this technique is not suitable since it involves messy construction work and requires evacuation. The idea behind the proposed method is to transform existing hollow masonry infill walls into strong and rigid infill walls by reinforcing them with relatively high strength precast concrete panels epoxy-glucd to the wall and dowel connected to the frame members to enhance the lateral stiffness of the frame. The panels to be assembled are small enough to be handled by two workers. All specimens were tested to failure under reversed cyclic quasi-static lateral loading and constant vertical load. All strengthened specimens exhibited superior performance compared to the reference specimens designed to represent the present state of ordinary RC frames with hollow brick infill walls plastered on both sides.

Occupant friendly seismic retrofit (OFR) of RC framed buildings Baran, M; Duvarci, M; Tankut, T; Ersoy, U; Ozcebe, G (2003-05-13) An innovative non-evacuation retrofitting technique is being developed for RC buildings. The introduction of cast-in-place RC infill walls is very effective, but involves messy construction work and requires evacuation. The proposed method transforms existing hollow masonry infill walls by reinforcing them with precast concrete panels epoxy glued to the wall and frame members. Three tests have so far been performed under reversed cyclic loading. The first specimen was an ordinary RC frame with hollow brick ...
Seismic Strengthening with Precast Concrete Panels - Theoretical Approach Baran, Mehmet; Canbay, Erdem; Tankut, Tugrul (2010-01-01) An economical, structurally effective and practically applicable seismic retrofitting technique has been developed on the basis of the principle of strengthening the existing hollow brick infill walls by using high strength precast concrete panels. The technique would not require evacuation of the building and would be applicable without causing much disturbance to the occupant. For this purpose, a total of eighteen reinforced concrete frames with hollow brick infill walls were tested under reversed cyclic ...
Seismic strengthening of reinforced concrete frames by precast concrete panels BARAN, MEHMET; Susoy, M.; Okuyucu, D.; Tankut, T. (Thomas Telford Ltd., 2011-05-01) An innovative occupant-friendly retrofitting technique has been developed for reinforced concrete (RC)-framed structures which constitute the major portion of the existing building stock. The idea is to convert the existing hollow brick infill wall into a load-carrying system acting as a cast-in-place concrete shear wall by reinforcing it with relatively thin high-strength precast concrete panels epoxy bonded to the plastered infill wall and epoxy connected to the frame members. In this study, results of 11...
Analytical study on seismic retrofitting of reinforced concrete buildings using steel braces with shear link Durucan, Cengizhan; Dicleli, Murat (2010-10-01) This paper is focused on a proposed seismic retrofitting system (PRS) configured to upgrade the performance of seismically vulnerable reinforced concrete (RC) buildings. The PRS is composed of a rectangular steel housing frame with chevron braces and a yielding shear link connected between the braces and the frame. The retrofitting system is installed within the bays of an RC building frame to enhance the stiffness, strength and ductility of the structure. The PRS and a conventional retrofitting system usin...
Fragility Based Assessment of the Structural Deficiencies in Turkish RC Frame Structures Ay, Bekir Özer; Erberik, Murat Altuğ (null; 2006-09-08) Low–rise and mid–rise reinforced concrete (RC) structures, which constitute approximately 75% of the total building stock in Turkey, are focused in this fragility–based assessment. The seismic design of three, five, seven and nine story RC frame structures are carried out according to the current earthquake codes and two dimensional analytical models are formed accordingly. The uncertainty in material variability is taken into account in the formation of structural simulations. Frame structures are categori...
