Dynamic properties of the soils at the Lotung test site, Lotung, Taiwan, are estimated from seismic vertical array measurements (input± output data sets) using both time-invariant and time-variant parametric modeling methods (system identi®cation). Soil properties are directly mapped from model parameters to an equivalent lumped mass model of the soil interval. Shear stiffness and damping ratio...

The evaluation of liquefaction potential of soil due to an earthquake is an important step in geosciences. This article examines the capability of Minimax Probability Machine (MPM) for the prediction of seismic liquefaction potential of soil based on the Cone Penetration Test (CPT) data. The dataset has been taken from Chi-Chi earthquake. MPM is developed based on the use of hyperplanes. It has...

The objective of this study is to create building damage hazard zonation area using fuzzy kohonen clustering network (FKCN) for physical parameter data clustering and inverse distance weighting (IDW) for data interpolation in Banda Aceh city, Indonesia. IDW algorithm is used alongside FKCN because of its simplicity. The physical parameter in this study consists of lithology, topographic zone an...

Peak ground acceleration (PGA) prediction is of great significance in the seismic design engineering structures. Machine learning a new method to predict PGA and does have some advantages. To establish explainable models PGA, 3104 sets uphole downhole records collected by KiK-net Japan were used. The feature combinations that make perform best selected through selection. peak bedrock (PBA), pre...

Probabilistic Seismic Hazard Assessment (PSHA) was carried out for the administrative region of Attica (Greece). Peak Ground Acceleration (PGA) and Velocity (PGV) values were calculated return periods 475 950 years five sub-areas covering entire region. PGA hazard curves Uniform Spectra (UHS) in terms spectral acceleration (Sa) generated Athens, Methana, capitals each island (Salamina, Aegina, ...

In active seismic regions an earthquake’s peak ground acceleration (PGA) is required information when designing a building. In this study we employ the state-of-the-art, Lagramge, equation-discovery system to induce an equation that is suitable for modeling the PGA and investigate its applicability. In contrast to traditional modeling techniques the Lagramge system does not presume the structur...

Abstract Seismic behavior analysis of the long-span cable-stayed bridge is a complex process involving different uncertainties. This paper performs sensitivity bridges using finite element method on Midas/Civil. They include types ground motions scaled to peak acceleration (PGA) levels, effect multi-support excitations due time-lag propagation or nonsynchronous excitations, and angle incidence ...

The seismic resilience of a structure has been evaluated using peak ground acceleration (PGA). Ground motion parameters such as source characteristics, local site conditions are used to forecast the PGA motion. This paper aims develop an Artificial Neural Network (ANN) based model predict PGA. Here, hypocentral distance ( R h y p o ${R}_{hypo}$ ), shear wave velocity V s 30 ${V}_{s30}$ and mome...
