Performance limits for structural walls: An analytical perspective

Kazaz, Ilker
Yakut, Ahmet
Recently proposed changes to modeling and acceptance criteria in seismic regulations for both flexure and shear dominated reinforced concrete structural walls suggest that a comprehensive examination is required for improved limit state definitions and their corresponding values. This study utilizes nonlinear finite element analysis to investigate the deformation measures defined in terms of plastic rotations and local concrete and steel strains at the extreme fiber of rectangular structural walls. Response of finite elements models were calculated by pushover analysis. We compare requirements in ASCE/SEI 41, Eurocode 8 (EC8-3) and the Turkish Seismic Code (TSC-07). It is concluded that the performance limits must be refined by introducing additional parameters. ASCE/SEI 41 limits are observed to be the most accurate yielding conservative results at all levels except low axial load levels. It is shown that neither EC8-3 nor TSC-07 specifies consistent deformation limits. TSC-07 suggests unconservative limits at all performance levels, and it appears to fall short of capturing the variation reflected in the calculated values. Likewise EC8-3 seems to fail to represent the variation in plastic rotation in contrast to several parameters employed in the calculation. More accurate plastic rotation limits are proposed.


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...
Response parameters that control the service, safety and collapse performances of a 253 m tall concrete core wall building in Istanbul
Budak, Erhan; Sucuoğlu, Haluk; Çelik, Ozan Cem (2022-10-01)
Seismic performance of a 253 m tall reinforced concrete core wall building constructed in Istanbul, designed according to performance-based seismic design principles, is assessed for determining the response parameters that control the serviceability, safety and collapse performance limit states. Serviceability performance is evaluated under the 50-year wind and 43-year earthquake whereas safety performance is assessed under the 2475-year earthquake. Collapse performance is elaborated through incremental dy...
Seismic behavior of vertical reinforced autoclaved aerated concrete (AAC) panel walls
Taghipour, Armin; Canbay, Erdem; Binici, Barış; Department of Civil Engineering (2016)
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...
Overlapping Lattice Simulation of Concrete Gravity Dam Collapse Simulations
SOYSAL, BERAT FEYZA; Aydın, Beyazıt Bestami; Tuncay, Kağan; Arıcı, Yalın; Binici, Barış (2017-09-01)
Estimating the collapse limit state of concrete gravity dams within the framework of performance based design is challenging due to the uncertainty in modelling the response of these systems and the strong dependence of the behavior on the ground motion. The purpose of the study is to investigate the seismic expected damage levels by using the overlapping lattice modeling (OLM) approach with incremental dynamic analysis (IDA) for two representative dam monoliths. OLM employs pin connected bar elements exten...
Seismic vulnerability assessment criteria for RC ordinary highway bridges in Turkey
AVŞAR, ÖZGÜR; Yakut, Ahmet (2012-07-10)
One of the most important and challenging steps in seismic vulnerability and performance assessment of highway bridges is the determination of the bridge component damage parameters and their corresponding limit states. These parameters are very essential for defining bridge damage state as well as determining the performance of highway bridges under a seismic event. Therefore, realistic damage limit states are required in the development of reliable fragility curves, which are employed in the seismic risk ...
