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 specimens. To overcome this issue, an experimental program was initiated to test six full‐scale AAC wall panel specimens. In the scope of this study, the in‐plane seismic behavior of AAC vertical load‐bearing wall panels was examined under constant axial load and two‐way cyclic lateral displacement excursions. First, the effect of axial loads on lateral behavior of reinforced AAC walls was investigated. For this purpose, four specimens composed of two and four AAC panels with and without axial loads were tested. Then, the effect of window opening was examined by conducting two more tests. The results of the experiments clearly indicated that the axial loads had a positive effect on the load carrying capacity. The window openings reduced the lateral strength and caused localization of the damage. The ultimate drift of the tested panels was found to be around 1%. The ability of estimating the measured moment versus curvature response of the tested specimens were examined for different adjacent panel assemblages. Finally, the code‐proposed equations to determine the lateral load capacity of AAC walls were critically reviewed in light of the experimental results.

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 ...
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 ...

The reinforced concrete shear walls of low- to mid-rise residential buildings, having height to length ratio ranging from 1 to 3, are more of a concern in research studies in recent years. Since the failure mode of these walls depends on the interaction between shear and flexural action, predicting the failure mode of this type of shear walls is not straight forward. While seismic behavior of highrise walls (i.e. aspect ratio greater than about 3) is almost known and theoretical assumptions matches well wit...

In this study, the in-plane seismic behavior of autoclaved aerated concrete (AAC) vertical load-bearing wall panels is examined. Because of the complex behavior of AAC shear walls under cyclic lateral loading and axial load, the design provisions are fundamentally important. The main objective of this study is to validate proposed design provisions for AAC structures in Turkey. Six specimens with different properties and geometries were constructed and tested at Structural Mechanics Laboratory of METU. Mech...

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...
