There are different techniques for masonry construction. Among these, confined masonry (CM) buildings may be regarded as an upgrade for unreinforced masonry (URM) buildings, which is the most common type. In Turkey, URM construction has been popular, especially up to the end of 1980s. These rather old URM buildings constitute a significant percent of the existing building stock. On the other hand, CM construction seems to be rare when compared to its URM counterpart in Turkey. This fact was also reflected in older versions of the Turkish seismic design codes as clauses regarding CM construction did not exist in these codes. In 2018, a new version of the Turkish seismic design code has been released, taking into account CM construction for the first time explicitly. In accordance with this fact, this study presents a comparison between the seismic performances of URM and CM building types at component and structure levels. The first phase of the study focuses on the capacity curves of URM and CM walls that have been idealized by using a piece-wise linear model with different performance limits. Empirical formulations from previous research are examined to determine the capacity curve parameters with the premise that they have the best estimate for the selected experimental dataset concerning URM and CM wall specimens. The second phase deals with the seismic performance in structure level for URM and CM buildings that are composed of masonry walls with idealized capacity curves as obtained in the first phase of the study. Capacity Spectrum Method is used for the analyses. The results reveal the superior behavior of CM construction over URM construction during seismic action.

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 SHEAR CAPACITY OF REINFORCED MASONRY PIERS Sucuoğlu, Haluk (American Society of Civil Engineers (ASCE), 1991-07-01) 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...
Seismic performance assessment of confined masonry buildings Çitiloğlu, Cihan; Erberik, Murat Altuğ; Department of Civil Engineering (2016) Although it is a known fact that confined masonry construction has many advantages over unreinforced masonry construction, its application has been very limited in Turkish construction practice. One of the reasons for this issue is that the seismic regulations in Turkey do not explicitly enforce or even encourage the use of confined masonry structural systems. Now, being on the verge of releasing a new version of the Turkish seismic code, it seems to be an appropriate time to adapt confined ma-sonry to the ...
Timber joint design: the geometric breakdown method Erman, E (Informa UK Limited, 2002-11-01) A large number of joints are developed as a result of various timber construction techniques, structural efficiency and cultural differences. Many joints are not used because they are not adapted or are inconvenient for modern manufacturing and construction technologies. Nonetheless, this construction heritage can be harnessed and adjusted for contemporary use. Significant cultural and social differences in timber jointing and construction technologies are reviewed. The Geometric Breakdown Method is develop...
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...
