Unreinforced infill walls are widely used non-structural elements in structures worldwide for architectural and engineering disciplines. The seismic capacity and response of unreinforced infill walls have been ignored until realizing the importance of these members during many seismic events and their aftermaths. Thus, the out-of-plane behavior of infill walls has become a topic that has been popular to investigate in the last decades for civil engineers especially. Although different infill materials are used to construct, traditional clay brick is the most preferred infill material. However, as new infill materials are discovered and developed, improving knowledge has become a necessity for different infill materials. Pumice concrete blocks are one of the popular infill materials used in recent years. This infill material is chosen due to its high thermal insulation, aesthetic concerns, and acoustic advantages. However, its seismic behavior, one of the characteristics of the pumice concrete infill walls, has not been discussed in detail in the literature. This study focuses on the out-of-plane behavior of clay brick and pumice concrete infill walls and their comparison. In addition, the presence of openings and different opening sizes were simulated for both clay brick and pumice concrete infill walls and tested under out-of-plane loading. Demand and design thickness estimation for both clay brick and pumice concrete infill walls were investigated for different spectral accelerations and story numbers of reinforced concrete structures.

Scale Effect on CFRP Strengthening of Infilled Reinforced Concrete Frames

The diagonal application of Carbon Fiber-Reinforced Polymer fabrics on hollow clay tile infill walls has been qualified as an efficient rehabilitation method for deficient reinforced concrete frames. However, majority of the experimental studies were conducted on 1/3-scaled RC frames and the effect of specimen scaling has not been questioned. In the current study, the results of an experimental campaign on 1/2-scaled RC frames are presented. Test specimens are grouped in two series having two different aspe...
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 ...
Cyclic Testing of Reinforced Concrete Double Walls
ALDEMİR, ALPER; Binici, Barış; Canbay, Erdem (2017-03-01)
Reinforced concrete double walls are semi-precast structural elements constructed with factory-produced concrete shells on two exterior sides and cast-in-place concrete in the middle of the section. Their use has been limited in seismic zones due to the difficulty of connecting the adjacent double walls for monolithic action, and providing suitable seismic details in the presence of the lattice girder that is used to hold the concrete shells together. These limitations were overcome with the invention of di...
Experimental evaluation of the in-plane behaviour of masonry wall infilled RC frames
Suzuki, Tomomi; Choi, Ho; Sanada, Yasushi; Nakano, Yoshiaki; Matsukawa, Kazuto; Paul, Devjyoti; Gulkan, Polat; Binici, Barış (2017-10-01)
This study focuses on the in-plane behaviour of unreinforced masonry (URM) infill walls installed in reinforced concrete (RC) frames. Five 1/4-scale model frames were designed based on a prototype RC building with URM infill walls in Turkey. The experimental parameters were the layout of the URM infill (its presence or absence), number of spans (single or double), number of stories (single or double), and stacking pattern of the URM infill (horizontal or vertical). Static cyclic loading tests were conducted...
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...
