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 one-third scale, one-bay, one-storey RC frames, tested by the authors, having the deficiencies commonly observed in residential buildings in Turkey, tested under reverse-cyclic lateral loading until failure are given in detail. It was clearly observed that the seismic performance indicators such as strength, lateral stiffness and energy dissipation capacity of the strengthened frames were significantly improved by the proposed technique.

Comprehensive Evaluation of AIMS Texture, Angularity, and Dimension Measurements Mahmoud, Enad; Gates, Leslie; Masad, Eyad; Erdoğan, Sinan Turhan; Garboczi, Edward (American Society of Civil Engineers (ASCE), 2010-04-01) Aggregates are the most widely used construction materials in the world in structures built from both asphaltic and portland cement concrete composites. The performance of these composites is affected by aggregate shape characteristics (e.g., angularity, texture, and dimensions). The aggregate imaging system (AIMS) is a computer automated system that was developed to measure aggregate shape characteristics using digital camera images of aggregates. This paper addresses four issues concerning AIMS measuremen...
Seismic strengthening of pin-connected precast concrete structures with external shear walls and diaphragms KAPLAN, HASAN; NOHUTCU, HALİL; ÇETİNKAYA, NİHAT; Yilmaz, Salih; Gonen, Hasan; Atimtay, Ergin (Precast/Prestressed Concrete Institute, 2009-12-01) Pin-connected precast concrete structures are widely used in some European countries of moderate seismicity. However, this structural system is not earthquake resistant because it does not have enough lateral stiffness or lateral-load resistance. Lack of a rigid diaphragm at the roof level imposes severe forces to connections.
Seismic vulnerability, behavior and design of tunnel form building structures Balkaya, C; Kalkan, E (Elsevier BV, 2004-12-01) Multi-story reinforced concrete tunnel form buildings are one of the common structural types in regions prone to high seismic risk due to the buildings inherent earthquake resistance and ease of construction. Despite their good performance during earthquakes in 1999 in Turkey, and abundance of such structures scattered worldwide, current seismic codes and design provisions provide insufficient guidelines for their seismic design. As a compensatory measure, a series of modal and nonlinear static analyses are...
Seismic behavior of autoclaved aerated concrete low rise buildings with reinforced wall panels Gökmen, Furkan; Binici, Barış; Canbay, Erdem (Springer Science and Business Media LLC, 2019-07-01) Reinforced Autoclaved Aerated Concrete (AAC) wall panels are more commonly used to construct load-bearing walls in low-rise prefabricated buildings located in seismic zones. In the scope of this study, the seismic response of buildings constructed with reinforced AAC wall panels was investigated. To this end, an in situ test was conducted on a two-story test building under reversed cyclic displacement excursions. It was determined that the test building could carry a lateral load of 60% more than its weight...
Effective flexural rigidities for ordinary reinforced concrete columns and beams AVŞAR, ÖZGÜR; BAYHAN, BEYHAN; Yakut, Ahmet (Wiley, 2014-04-25) Current effective flexural rigidities proposed for use in design and analyses of reinforced concrete structures have been examined. The level of accuracy in the estimation of section rigidity plays a very important role in determining realistic values for the structural stiffness and hence the seismic forces imposed. The most significant parameters influencing the effective rigidity, which reflects the effect of cracking as well as the theoretical yielding of reinforced concrete sections, have been determin...
