This book was released on 2013-01 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seismic evaluation of existing facilities and design of earthquake-resistant structures requires estimation of strong ground motion parameters. Ground motion prediction equations are derived for estimating strong ground motion parameters. Traditionally, ground motion prediction equations are developed using statistical regression analyses. This book presents a very promising application of the powerful and versatile neural network approach to the derivation of ground motion prediction equations using Japanese earthquake records and site characteristics. Multi-layer perceptron neural network models with back-propagation learning scheme have been developed to predict strong ground motion parameters that are of primary significance in earthquake engineering using the actual seismic data without any simplification and assumptions. Statistics of the results presented indicate that artificial neural network is capable of learning and representing the local variations quite accurately. This book is intended to help structural engineers in selection of appropriate characterization of ground motion for engineering applications that are used in seismic analysis and design.

Available in PDF, EPUB and Kindle. Book excerpt: The effect of the earthquake ground motion parameters on the probabilistic loss estimation of buildings is the major interest of this study. For the seismic performance assessment, real ground motion records from the past earthquakes are required. Estimation of repair costs in future earthquakes is the major component for seismic loss analysis. This study addresses the sensitivity of the statistical characteristics of ground motions contributing to the building loss. Among these characteristics are the ground-shaking intensity (Arias Intensity), duration, and frequency at the middle of strong-shaking phase of the ground motion. These parameters are vital in determining the seismic response of the building structure. A fine study on the sensitivity of the seismic response and corresponding loss of the building structure to ground motions model parameters is carried out using Performance-based Earth- quake Engineering and Performance Assessment Computational Tool, respectively. But due to the scarcity of moderate to large earthquakes, the real records fail to match the required characteristics of motions, as there are insufficient set of data available for analysis to be carried out. Even, the of technique scaling ground motions results in overall unrealistic properties. This has led to the simulation of ground motions which will provide the additional and hopefully accurate predicted information on characteristics of the moderate to large earthquakes. Hence, a fully non-stationary stochastic model for strong earthquake ground motion model is considered which employs the statistical characteristics (waveform parameters) as model parameters matched with those of identified for a large sample of recorded ground motions for specified earthquake and site characteristics, to deliver simulated ground motions to examine the building loss metrics, which depends on the uncertainties in various analysis process starting from obtaining Intensity Measure (IM), Demand parameters (EDPs) to the repair cost estimates. From the predictive equations, specified earthquake and site characteristics results in the model parameters.Further, the validity of simulated ground motion time series representing the real ground shaking during future earthquakes is a crucial step. This study employs the hybrid broad- band ground motion simulation applied simulations to validate against the real records. With the help of hybrid approach, making use of wave propagation phenomena and site response characterization, effort has been taken for validation of these simulated ground motions is conducted for the sensitivity of seismic response and loss for these simulated ground motions.

Available in PDF, EPUB and Kindle. Book excerpt: Performance-based earthquake engineering (PBEE) quantifies the seismic hazard, predicts the structural response, and estimates the damage to building elements, in order to assess the resulting losses in terms of dollars, downtime, and deaths. This dissertation focuses on the ground motion selection that connects seismic hazard and structural response, the first two elements of PBEE, to ensure that the ground motion selection method to obtain structural response results is consistent with probabilistic seismic hazard analysis (PSHA). Structure- and site-specific ground motion selection typically requires information regarding the system characteristics of the structure (often through a structural model) and the seismic hazard of the site (often through characterization of seismic sources, their occurrence frequencies, and their proximity to the site). As the ground motion intensity level changes, the target distribution of important ground motion parameters (e.g., magnitude and distance) also changes. With the quantification of contributing ground motion parameters at a specific spectral acceleration (Sa) level, a target response spectrum can be computed using a single or multiple ground motion prediction models (GMPMs, previously known as attenuation relations). Ground motions are selected from a ground motion database, and their response spectra are scaled to match the target response spectrum. These ground motions are then used as seismic inputs to structural models for nonlinear dynamic analysis, to obtain structural response under such seismic excitations. This procedure to estimate structural response results at a specific intensity level is termed an intensity-based assessment. When this procedure is repeated at different intensity levels to cover the frequent to rare levels of ground motion (expressed in terms of Sa), a risk-based assessment can be performed by integrating the structural response results at each intensity level with their corresponding seismic hazard occurrence (through the seismic hazard curve). This dissertation proposes a more rigorous ground motion selection methodology which will carefully examine the aleatory uncertainties from ground motion parameters, incorporate the epistemic uncertainties from multiple GMPMs, make adaptive changes to ground motions at various intensity levels, and use the Conditional Spectrum (CS) as the new target spectrum. The CS estimates the distribution (with mean and standard deviation) of the response spectrum, conditioned on the occurrence of a target Sa value at the period of interest. By utilizing the correlation of Sa values across periods, the CS removes the conservatism from the Uniform Hazard Spectrum (which assumes equal probabilities of exceedance of Sa at all periods) when used as a target for ground motion selection, and more realistically captures the Sa distributions away from the conditioning period. The variability of the CS can be important in structural response estimation and collapse prediction. To account for the spectral variability, aleatory and epistemic uncertainties can be incorporated to compute a CS that is fully consistent with the PSHA calculations upon which it is based. Furthermore, the CS is computed based on a specified conditioning period, whereas structures under consideration may be sensitive to multiple periods of excitation. Questions remain regarding the appropriate choice of conditioning period when utilizing the CS as the target spectrum. To advance the computation and the use of the CS in ground motion selection, contributions have been made in the following areas: The computation of the CS has been refined by incorporating multiple causal earthquakes and GMPMs. Probabilistic seismic hazard deaggregation of GMPMs provides the essential input for such refined CS computation that maintains the rigor of PSHA. It is shown that when utilizing the CS as the target spectrum, risk-based assessments are relatively insensitive to the choice of conditioning period when ground motions are carefully selected to ensure hazard consistency. Depending on the conditioning period, the structural analysis objective, and the target response spectrum, conclusions regarding appropriate procedures for selecting ground motions may differ.

Book excerpt: This volume collects several extended articles from the first workshop on Best Practices in Physics-based Fault Rupture Models for Seismic Hazard Assessment of Nuclear Installations (BestPSHANI). Held in 2015, the workshop was organized by the IAEA to disseminate the use of physics-based fault-rupture models for ground motion prediction in seismic hazard assessments (SHA). The book also presents a number of new contributions on topics ranging from the seismological aspects of earthquake cycle simulations for source scaling evaluation, seismic source characterization, source inversion and physics-based ground motion modeling to engineering applications of simulated ground motion for the analysis of seismic response of structures. Further, it includes papers describing current practices for assessing seismic hazard in terms of nuclear safety in low seismicity areas, and proposals for physics-based hazard assessment for critical structures near large earthquakes. The papers validate and verify the models by comparing synthetic results with observed data and empirical models. The book is a valuable resource for scientists, engineers, students and practitioners involved in all aspects of SHA.
