Factors Affecting Site-Specific Response Analysis

AbstractThe engineering purpose of a site-specific response analysis is to estimate the uniform hazard acceleration spectrum on ground surface for selected level. One mandatory components site analyses one or more representative time histories that need be scaled with respect calculated seismic level site. The selection and scaling procedures earthquake records play an important role in this approach. effects differences using two different approaches are studied: motion parameters scaling. A set homogeneous prediction relationships developed peak acceleration, velocity, root-mean-square Arias intensity, cumulative absolute maximum spectral intensity based parameter scaling.The uncertainties associated considered as epistemic aleatory source characteristics, soil profile, properties. Aleatory variability due intrinsic randomness natural systems; it cannot reduced additional data (Passeri et al. 2020), however; its may modeled by probability distribution functions. Thus, possibility determine all possible input records, profiles, dynamic path large number compatible site-dependent terms fault mechanism, magnitude, distance range recorded stiff conditions. Likewise, profiles account condition variability. related properties shear modulus analyses. methodology proposed probabilistic assessment factors involved analysis. spectra obtained from case study compared models literature.
