Masonry buildings have been, and remain, a popular form for economically enclosing space. Whereas such buildings are safe under gravity loads, most are vulnerable to horizontal loads due to earthquakes. Observations following an earthquake and experimental programs have shown that piers between openings are the most vulnerable part of a masonry building, and that the failure of such piers is due in the majority of cases to shear (or diagonal tension). Accordingly, the study described concerns the seismic response of reinforced masonry piers that exhibit a shear mode of failure. The study consists of two parts. First the results of an experimental program on reinforced masonry piers under cyclic lateral loads simulating seismic excitation are presented. Then several code provisions governing the seismic design of masonry are evaluated in view of the experimental observations, and a new seismic shear design concept is proposed for reinforced masonry piers and walls where the design strength is defined as the onset of diagonal web cracking. Shear reinforcement is considered as a mechanical component that provides postcracking ductility. Validity of the proposed concept is verified by comparing the computed design parameters with the available experimental data.

Evaluation of the Predictive Models for Stiffness, Strength, and Deformation Capacity of RC Frames with Masonry Infill Walls Turgay, Tahsin; Durmus, Meril Cigdem; Binici, Barış; Ozcebe, Guney (American Society of Civil Engineers (ASCE), 2014-10-01) Buildings with masonry infill walls (MIWs) in reinforced concrete (RC) frames are commonly used all around the world. It is well known that infill walls may affect the strength, stiffness, and displacement ductility of the structural system. Different approaches have been adopted in different codes and guidelines to consider the stiffness and strength contribution of MIWs on RC frame behavior. This study compares the ability of the existing guidelines to estimate stiffness, strength, and deformability of RC...
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...
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 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...
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...
