Performance-based seismic evaluation aims to provide information on expected seismic performance of structures in measurable and meaningful terms for decision makers (performance objectives). The Pacific Earthquake Engineering Research (PEER) Center utilized the performance-based earthquake engineering (PBEE) framework by linking the earthquake scenarios, design ground motions, structural demand, and performance variables. PBEE procedure may be simplified by decoupling the evaluation of the design ground motion levels (probabilistic seismic hazard assessment, PSHA) and that of the structural demand due to design ground motions (probabilistic seismic demand assessment, PSDA). The objective of this chapter is to present the vector-valued implementation of PEER PBEE approach. Key points of PSDA methodology such as selection of engineering demand parameters along with the intensity measures, effects of ground motion record scaling, and construction of probabilistic seismic demand models are discussed. Integration of vector-valued intensity measures into these models is explained in detail. Results of a recent study investigating the effect of vertical ground motions on ordinary highway bridges is used to demonstrate the application of PEER PBEE framework for a particular class of structures.

Estimating the Liquefaction Related Geotechnical Hazards in Probabilistic Seismic Hazard Assessment Framework Gülerce, Zeynep (2016-06-26) The objective of this study is to develop a performance-based earthquake engineering (PBEE) framework for the liquefaction-related hazards and estimate the hazard levels for liquefaction-related engineering demand parameters (EDPs) in a probabilistic manner. Two efficient, sufficient, and hazard compatible EDPs: probability of liquefaction (PL) and post-liquefaction settlement (δL) are selected. Seismic demand models that explain the relationship between these EDPs and ground motion IMs are employed in a se...
An efficient seismic intensity measure for seismic risk analysis of structures Çelik, Ozan Cem (null; 2010-12-01) In a seismic fragility or seismic margins assessment, the estimated structural system response is conditioned on a measure of seismic intensity. The U.S. Geological Survey currently stipulates the site-dependent seismic hazard by mapping the spectral acceleration at a frequency of 2% probability of being exceeded in 50 years. The scatter in structural responses at a given intensity measure (IM) due to record-to-record variability in ground motion ensembles used in nonlinear time history analysis of structur...
A Predictive model for maximum interstory drift ratio (MIDR) and its implementation in probability-based design and performance assessment procedures g Eroğlu Azak, Tuba; Akkar, Sinan; Department of Civil Engineering (2013) Estimating nonlinear deformation demands is important for the implementation of rational seismic design and assessment methodologies to ensure the safe and reliable response of existing and new buildings against seismic action. The nonlinear deformation demand estimations should consider the variability inground motions as well as the uncertainties involved in structural response. This study presents probability-based seismic design and assessment procedures for code-confirming low- and mid-rise reinforced ...
An improvement to linear-elastic procedures for seismic performance assessment Gunay, Mehmet Selim; Sucuoğlu, Haluk (Wiley, 2010-07-10) An improved linear-elastic analysis procedure is developed in this paper as a simple approximate method for displacement-based seismic assessment of the existing buildings. The procedure is mainly based on reducing the stiffness of structural members that are expected to respond in the inelastic range in a single global iteration step. Modal spectral displacement demands are determined from the equal displacement rule. Response predictions obtained from the proposed procedure are evaluated comparatively by ...
Estimation of earthquake insurance premium rates based stochastic methods Deniz, Aykut; Yücemen, Mehmet Semih; Department of Civil Engineering (2006) In this thesis, stochastic methods are utilized to improve a familiar comprehensive probabilistic model to obtain realistic estimates of the earthquake insurance premium rates in different seismic zones of Turkey. The model integrates the information on future earthquake threat with the information on expected earthquake damage to buildings. The quantification of the future earthquake threat is achieved by making use of the seismic hazard analysis techniques. Due to the uncertainties involved, the hazard th...
