Experimental Study on Seismic Strengthening of Reinforced Concrete Frames by Precast Concrete Panels

Tankut, Tugrul
The purpose of this study is to investigate the behavior of reinforced concrete (RC)frames under cyclic loads strengthened by using precast concrete (PC) panels. The idea is to transform the existing hollow brick infills into strong and rigid infills by bonding relatively high-strength PC panels with a thin layer of epoxy mortar By this method, the seismic behavior of the frame is improved. For this purpose-one being reference-a total of 11 one-third scale, one-hay, two-story deficient RC frames were tested under reversed cyclic lateral loads. Six different panel types were used for strengthening purposes. It was observed that the strength, lateral stiffness, and energy dissipation capacity of strengthened frames were significantly improved.


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 upgrading of reinforced concrete frames with structural steel elements
Özçelik, Ramazan; Binici, Barış; Department of Civil Engineering (2011)
This thesis examines the seismic internal retrofitting of existing deficient reinforced concrete (RC) structures by using structural steel members. Both experimental and numerical studies were performed. The strengthening methods utilized with the scope of this work are chevron braces, internal steel frames (ISFs), X-braces and column with shear plate. For this purpose, thirteen strengthened and two as built reference one bay one story portal frame specimens having 1/3 scales were tested under constant grav...
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...
Influence of the shear wall area to floor area ratio on the seismic performance of existing reinforced concrete buildings
Günel, Ahmet Orhun; Burak Bakır, Burcu; Department of Civil Engineering (2013)
An analytical study is performed to evaluate the influence of shear wall area to floor area ratio on the behavior of existing mid-rise reinforced concrete buildings under earthquake loading. The seismic performance of five existing school buildings with shear wall ratios between 0.00% and 2.50% in both longitudinal and transverse directions and their strengthened counterparts are evaluated. Based on the structural properties of the existing buildings, additional buildings with varying shear wall ratios are ...
Cyclic behaviour of precast beam-to-column connections: An experimental and numerical investigation
Torra-Bilal, Ines; Mahamid, Mustafa; Baran, Eray (2022-01-01)
The main objective of this study is to examine the behavior of hybrid beam-column connections with numerous detailing methods to be incorporated in precast moment resisting frames under simulate reversed cyclic loading, which will lead to better understanding of their performance and safer seismic applications. To accomplish the research objectives, an integrated experimental and numerical study was conducted. The experimental part consisted of reversed cyclic loading of precast concrete beam-column specime...
