Real structures are almost always irregular, as perfect regularity is an idealisation that very rarely occurs. Structural irregularities may vary dramatically in their nature and, in principle, are very difficult to define. In comparison with research efforts dealing with horizontally irregular structures, studies aimed at predicting the behavior of structures with rough layouts in elevation are small in number. Due to drawbacks of irregular structures under seismic excitations, engineers are less confident to design these type of buildings. Vertical irregularities designated in buildings are due to many reasons such as strength, stiffness and mass irregularities and the dynamic behavior of the structures are related with those three parameters. The objective of this study is to carry out a comprehensive research to investigate the effect of vertical irregularities especially soft story on seismic response of structures and to examine efficiency and validity of code specified definitions of vertical irregularities. Typical RC Frames were selected from code designed buildings according to TEC 2007 and irregularities were introduced to reference (base case) frames. Definition of soft story irregularity was investigated.

Effect of infill walls on structural behavir of rc buildings with vertical irregularities
Akansel, Vesile Hatun; Yakut, Ahmet; Moehle, Jack (null; 2017-01-09)
The building structures are generally irregular and regularity is only an idealization that rarely occurs. Structural irregularity may be classified as in- plan and in-elevation. In this study, vertical irregularities are in consideration since less research has been done compared to the in-plan irregularities. Vertical irregularities designated in buildings are due to many reasons such as mass, stiffness and strength irregularity and the dynamic behavior of the structures are totally related with those thr...
Influence of the shear wall area to floor area ratio on the seismic performance of existing reinforced concrete buildings
Günel, Ahmet Orhun; Burak Bakır, Burcu; Department of Civil Engineering (2013)
An analytical study is performed to evaluate the influence of shear wall area to floor area ratio on the behavior of existing mid-rise reinforced concrete buildings under earthquake loading. The seismic performance of five existing school buildings with shear wall ratios between 0.00% and 2.50% in both longitudinal and transverse directions and their strengthened counterparts are evaluated. Based on the structural properties of the existing buildings, additional buildings with varying shear wall ratios are ...
Investigation of seismic isolation efficiency for building structures
Özdemir, Seda; Yakut, Ahmet; Ay, Bekir Özer; Department of Earthquake Studies (2016)
The main goal of this study is to assess the efficacy of seismic isolation for building type of structures with different structural systems, namely, dual systems and moment frame systems having also different number of floors. Specific to this study, the main parameters employed for efficacy assessment will be the interstorey drift ratio and floor acceleration since both structural and non-structural damage to be occured in a system are directly related to these two parameters. To assess the variations in inter...
Influence of reinforced column details on building collapse envelope
Vara, Güncel; Binici, Barış; Department of Civil Engineering (2022-6)
Building collapse envelopes are simple yet reliable data representations used for depicting load-carrying and deformation capacities of reinforced concrete buildings and the relationship of these two types of performance-related quantities. These envelopes exhibit variations when structural parameters of the buildings they represent are tweaked. This study is intended to investigate the influence of reinforced concrete column details on building collapse envelopes. Numerical models of two five-story residen...
Impact of local site effects on seismic risk assessment of reinforced concrete bridges
Ozsarac, Volkan; Ricardo, Monteiro; Askan Gündoğan, Ayşegül; Calvi, Gian Michele (2023-01-01)
In most practical applications of performance-based earthquake engineering, the local site characteristics are considered simplistically, and soil-structure interaction effects are ignored. Within such a conventional approach, the ground motion record selection uses the time-averaged shear-wave velocity in the top 30 m of the soil profile (VS30) as the main proxy to represent the site where the structure is located. This study aims to assess the impact of local site effects on the risk assessment of reinfor...
