Successful seismic performance of well-designed and constructed precast concrete members is crucial for sustainable, economical and high speed construction. The main disadvantage of precast concrete is the difficulty of detailing the connection region between the vertical and horizontal load bearing elements to ensure structural integrity. Double wall system, being a semi-precast approach, consists of two precast reinforced concrete layers encasing a cast-in-place concrete layer which is usually employed to create a monolithic connection between the wall and the slab. Seismic performance tests on double walls is scarce due to its limited use in earthquake prone regions. To gain a better understanding of the seismic behavior of double walls, four full-scaled specimens with different section shapes were tested subjected to cyclic horizontal loads at Middle East Technical University1 . In this paper, test results are presented along with the comparisons with simple analytical models and performance limits presented in ASCE/SEI-41, Eurocode 8, and Turkish Earthquake Code 2007. It has been found that while TEC2007 provided estimations with the highest standard deviation, ASCE/SEI-41-06 demonstrated a better agreement with the tests results

Experimental investigation of structural systems made of sheathed cold-formed steel wall panels Pehlivan, Barış Mert; Baran, Eray; Department of Civil Engineering (2023-1-12) Cold-formed steel (CFS) structural systems are considered to be an innovative and newly developing construction method. Because of advantages such as lower fabrication periods, high strength/weight ratio and ease of construction, CFS structural systems have been used increasingly all around the world, including seismically active areas. Although there have been many studies in the literature, CFS structural systems are relatively new for the civil engineering practice and few existing specifications regardi...
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 behavior of reinforced autoclaved aerated concrete wall panels TAGHIPOUR, ARMIN; Canbay, Erdem; Binici, Barış; ALDEMİR, ALPER; Uzgan, Ugur; ERYURTLU, ZAFER (2018-09-01) Vertical reinforced autoclaved aerated concrete (AAC) panel systems are among attractive alternatives for low‐rise buildings. The popularity of AAC panels in building construction is increasing due to their unique material properties, such as being light weight, good insulator, fire resistant combined with having high speed of erection and ease of quality control. However, past experimental evidence on the seismic response of reinforced vertical panels is rather limited with few tests on multi‐panel specime...
Seismic response of a single story innovative steel frame system Dicleli, Murat (2005-01-01) The presented research studies the seismic response of a new braced steel frame type and a new design philosophy that will focus on minimizing damage to the essential structural members and ensuring satisfactory post-earthquake performance of steel buildings under service loads with minimal rehabilitation costs. The proposed frame type is composed of beams and columns with rigid connections, chevron braces and a conventional energy-dissipating member called the shear element connected between the braces and...
Performance Assessment of Turkish Residential Buildings for Seismic Damage and Loss Estimation Un, Elif M.; Erberik, Murat Altuğ; Askan Gündoğan, Ayşegül (2015-04-01) This study aims to present an integrated method in a probabilistic manner for seismic performance assessment of Turkish residential buildings, which can be used as a tool to estimate earthquake losses due to structural damage. In particular, the objective is to determine the performances of different types of residential buildings for predicting the potential seismic loss in terms of casualties (death toll) for a highly populated city in northwestern Turkey. The main phases of this study are seismic hazard,...
