Effect of AAC Infill Walls on Structural System Dynamics of a Concrete Building

The effect of autoclaved aerated concrete (AAC) infill walls on the structural system dynamics of a two-story reinforced concrete building is investigated using its finite element structural model, which is calibrated to simulate the acceleration-frequency response curves from its forced vibration test. The model incorporating the AAC infill walls by equivalent diagonal struts captures the increase in lateral stiffness of the building and the torsional motions induced due to the asymmetrically placed AAC infill walls. A higher strut width coefficient than in ASCE/SEI 41-06 is recommended to model the stiffness of the AAC infill walls in the elastic range.


Effect of inelastic behaviour of load bearing walls on the frame–wall structural systems
Güler, Gökay; Sarıtaş, Afşin; Department of Civil Engineering (2009)
The purpose of this study is to investigate the influence of material and geometric nonlinearities occurring in beams, columns and walls of RC frame-wall structural systems when undergoing severe ground excitations. For this purpose, a low-rise RC building is considered with and without walls, and the joining beams and columns are designed with the strong-column weak-beam concept. The dimensions, material properties and the reinforcement amounts are calculated in accordance with the values suggested in desi...

In forced vibration testing, a vibration generator bolted to one of the top floors excites the building with a known sinusoidal force. Sweeping the frequency of the vibration generator, steady-state structural responses are recorded at each operated frequency by accelerometers deployed throughout the building. Dynamic properties of the structural system are then identified from acceleration-frequency response curves by using well-established methods in the structural dynamics area, which do not require soph...
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...
Effect of Shear Wall Area to Floor Area Ratio on the Seismic Behavior of Reinforced Concrete Buildings
Burak Bakır, Burcu (American Society of Civil Engineers (ASCE), 2013-11-01)
An analytical study is performed to evaluate the effect of shear wall area to floor area ratio on the seismic behavior of midrise RC structures. For this purpose, 24 midrise building models that have five and eight stories and shear wall ratios ranging between 0.51 and 2.17% in both directions are generated. Then, the behavior of these building models under earthquake loading is examined by carrying out nonlinear time history analyses. In the analyses, seven different ground motion records are applied to th...
Effect of out-of-plane behavior on seismic fragility of masonry buildings in Turkey
Ceran, Hasan Burak; Erberik, Murat Altuğ (Springer Science and Business Media LLC, 2013-10-01)
This study focuses on the evaluation of seismic safety of unreinforced masonry buildings in Turkey by using fragility curves generated for two behavior modes of load bearing walls: in-plane and out-of-plane. During generation of fragility curves, a force-based approach has been used. There exist two limit states in terms of base shear strength for in-plane behavior mode and flexural strength for out-of-plane behavior mode. To assess the seismic vulnerability of unreinforced masonry buildings in Turkey, frag...
