A microzonation study deals with the classification of hazards in a town or city terms surface ground motions that result from amplification and resonance frequency soils against seismic tremors. This paper presents peak amplitude for Lahore city, Pakistan. In order to recognize local soil effects covered geology at 159 sites horizontal-to-vertical spectral ratio (HVSR) Nakamura method was impl...
Being a country exposed to strong seismicity, the estimation of seismic hazard in Tajikistan is essential for urbanized areas, such as rapidly growing capital city Dushanbe. To ensure people’s safety and adequate construction work, detailed microzonation key proper planning. Existing estimations date back 1978; they are based on engineering geological investigations observed macroseismic data. ...
Pompeii Archaeological Park is the best laboratory for study of seismic site effects on cultural heritage: ancient was destroyed and buried by 79 AD Vesuvian eruption and, furthermore, it also affected 62–63 strong earthquake. Large sectors city were reconstructed after this earthquake while other parts still under reconstruction when fall-out pyroclastic density currents Roman city. In order t...
One of the most important parameters used to determine dynamic properties soil layers is shear wave velocity. In geotechnical earthquake engineering, velocity modulus, which provides input for design earthquake-resistant structures. Although there are measurement methods in field studies velocity, they may not be economical some cases. this study, empirical correlations between and penetration ...
Effect of Randomness of Parameters on Amplification of Ground Motion in Saturated Sedimentary Valley
Based on Biot’s theory and the indirect boundary element method (IBEM), Monte Carlo is utilized to generate random samples calculate displacement response of a saturated sedimentary valley under SV wave incidence. The purpose this paper explore effects randomness porosity, permeability coefficient, geometric shape seismic amplification effect complex sites. It shown that change media porosity i...
