Structures must have a reasonable seismic safety margin in order to ensure life-safety as well as to prevent structural collapse caused by earthquakes. On the other hand, the cost-efficiency and economy of structures are important and integral parts of structural engineering. The main aim of the current study is to propose an efficient methodology for designing cost-efficient multi-story special steel moment-resisting frames at predefined levels of seismic collapse safety. To achieve this purpose, a seismic collapse safety assessment technique is in-tegrated with performance-based design optimization in the present study. In order to illustrate the advantages of the proposed methodology, three design examples of 3-, 6-and 12-story special steel moment-resisting frames are presented. The numerical results show that by with a 25% increase in the optimal weight of the structures, their seismic collapse capacity increases by more than 50%.

COLLAPSE FRAGILITY ANALYSIS OF REINFORCED CONCRETE TALL BUILDINGS Budak, Erhan; Çelik, Ozan Cem; Sucuoğlu, Haluk; Department of Civil Engineering (2022-9-02) Seismic performance of a 253 m tall reinforced concrete core wall building in Istanbul, designed according to performance-based seismic design principles, was assessed to determine the response parameters that control the serviceability, safety and collapse performance limit states. An ambient vibration test of the building was performed to identify its dynamic properties, including the damping properties for service loads. A three- dimensional linear elastic finite element structural model of the building ...
Seismic fragilities for non-ductile reinforced concrete frames - Role of aleatoric and epistemic uncertainties Çelik, Ozan Cem (2010-01-01) Seismic fragilities are essential to earthquake loss estimation and performance-based earthquake engineering in regions of high seismicity. Construction practices for frames in regions of moderate seismicity are quite different, and such frames have received less attention in the literature. Fragilities for performance levels identified in recent seismic regulations are developed herein for reinforced concrete frames designed for gravity load in low-seismic regions using probabilistic non-linear finite elem...
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 vulnerability, behavior and design of tunnel form building structures Balkaya, C; Kalkan, E (Elsevier BV, 2004-12-01) Multi-story reinforced concrete tunnel form buildings are one of the common structural types in regions prone to high seismic risk due to the buildings inherent earthquake resistance and ease of construction. Despite their good performance during earthquakes in 1999 in Turkey, and abundance of such structures scattered worldwide, current seismic codes and design provisions provide insufficient guidelines for their seismic design. As a compensatory measure, a series of modal and nonlinear static analyses are...
SEISMIC RISK ASSESSMENT OF AN INSTRUMENTED REINFORCED CONCRETE BUILDING PAÇARIZI, FURKAN; Çelik, Ozan Cem; Department of Civil Engineering (2022-11) The expected seismic performance of existing buildings during future earthquakes is always a concern for public administrations in pre- and post-earthquake planning as well as for general public. Seismic risk of these buildings, whether they will fulfill different performance-based design objectives when subjected to earthquake ground motions of different intensities, has to be evaluated. Such an evaluation for an existing building requires an accurate finite element model of the building. This study ...
