Autoclaved aerated concrete (AAC) reinforced panels are used to construct easily erected, energy efficient, low-rise prefabricated buildings. This study aims to contribute to the understanding of the seismic response of reinforced-AAC-wall-panel buildings. For this purpose, a full-scale two-story building constructed on a building site by using reinforced AAC panels was tested under two-way cyclic displacement excursions up to near collapse. The test results showed that the test building had a lateral load capacity of 1.6 times its weight with a global displacement ductility of about 3.5. The first story of the building sustained significant damage due to the rocking of the building followed by panel crushing. The slab-wall connections did not sustain any damage during the test. Afterward, numerical models of AAC panels were calibrated by using component test results from the literature. Nonlinear static analysis was conducted on the test building by using the proposed modeling approach. A reasonably good agreement was observed between the test results and numerical model estimations both for the envelope and the cyclic response. Finally, incremental dynamic analyses were conducted on the test building in order to observe the response of the building under severe earthquake motions. The dynamic analyses results showed that AAC buildings are expected to behave in their pre-yielding regions under design earthquakes. Furthermore, the reserved ductility and available over strength can enable AAC buildings survive the maximum considered earthquakes without collapse.

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...

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 ...

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...

AKIN, EMRE; Canbay, Erdem; Binici, Barış; Ozcebe, Guney (2015-06-01)
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...
Vulnerability assessment of reinforced concrete moment resisting frame buildings
Erduran, Emrah; Yakut, Ahmet (2007-04-01)
A detailed seismic performance assessment procedure has been developed for reinforced concrete (RC) frame buildings with masonry infill walls. The procedure is based on member damage functions, in terms of interstory drift ratios. These functions are developed for the primary components, namely, columns, beams, and infill walls. For developing these functions, analytical investigations to determine the influence of several parameters on the damageability of components were combined with experimental data. A...
