A simple procedure to estimate the local displacement demands in regular frame-type structures that respond elastic limits is described. Given spectral and beam-to-column stiffness ratio, estimates maximum ground story interstory drifts along height of structure. total 145 near-fault motions recorded on dense-to-firm soil sites are used for evaluation procedure. The approximate drift computed from this exact results 27,550 response history analyses calculating error statistics. calculations...
In the wake of 1999 earthquake destruction in Turkey, urgent need has arisen to evaluate benefits loss mitigation measures that could be undertaken strengthen existing housing stock. this study, a benefit-cost analysis methodology is introduced for comparative evaluation several seismic retrofitting applied representative apartment building located Istanbul. The performed probabilistically through development fragility curves structure its different retrofitted configurations. By...
The current spectral shapes in the Turkish Seismic Code ( TSC) are based on broadly described geological conditions, ignoring fault distance or magnitude dependencies ordinates. To address this deficiency, a data set created from suite of 112 strong ground motion records 57 earthquakes that occurred between 1976 and 2003 has been used to develop horizontal attenuation relationships for Turkey. This way it is possible construct hazard-consistent design spectra any national seismic region....
Binaların doğrusal olmayan deprem tepkisinin tahmini bir zorluk olmaya devam etmektedir. Sıradan yapıların sismik talebini ve davranışını makul şekilde tahmin edebilmek için farklı hassasiyette pek çok yöntem önerilmiştir. Yöntemlerin tahminleri genellikle NRHA'nın (Doğrusal Olmayan Tepki Geçmişi Analizi) “kesin” sonuçlarıyla karşılaştırılır. Bu çalışmada, NRHA sonuçlarına dayalı olarak yönetmeliklerce belirlenmiş detaylı değerlendirme pratik kullanılan bazı ön tahminleri, güçlü yer...
Abstract In 1999, the eastern coastline of Marmara region (Turkey) witnessed increased seismic activity on North Anatolian fault (NAF) system with two damaging earthquakes ( M 7.4 Kocaeli and 7.2 Duzce) that occurred almost three months apart. These events have reduced stress western segment NAF where it continues under Sea. The undersea segments been recently explored using bathymetric reflection surveys. recent findings helped scientists to understand seismotectonic environment basin,...
Two basic characteristics of reinforced concrete structures play an important role in determining response to strong ground motions. They are the changes stiffness and energy dissipation capacity. Both can be related maximum displacement. Results dynamic tests frames used illustrate effects on It is shown that inelastic interpreted terms linearly elastic analysis by reference a fictitious linear structure whose damping determined as function assumed or known This leads simplified method for...
In the aftermath of two destructive urban earthquakes in 1999 Turkey, empirical models strong motion attenuation relationships that have been previously developed for North American and European utilized a number national seismic hazard studies. However, comparison evidence estimates present significant differences. For reason, data set created from suite 100 vertical ground records 47 occurred between 1976 2002 has used to develop Turkey. A consistent was derived predicting peak...

For accurate analytical assessment of performance and damage in reinforced concrete members, well-defined deformation limits at particular states are required. With advanced computationally intensive finite element analyses, we establish yield ultimate limit for adequately confined rectangular structural walls terms drift ratio, plastic rotation, curvature. To investigate the walls, a parametric study on isolated cantilever wall models is performed. The primary variables...

The main objective of the SERAMAR project has been to utilize current tools for earthquake risk assessment and establish a unique partnership between universities, professional associations, local governments, which might serve as model similar future activities in Turkey adjacent areas. In order reach this goal, thorough microzonation survey program combined with vulnerability social preparedness studies anticipation damaging seismic event were conducted. paper is focused on related...
An analytical solution for the shape functions of a beam segment supported on generalized two-parameter elastic foundation is derived.
