The cone penetration test (CPT) has been the de facto field exploration method in geotechnical engineering for decades. Variations of CPT can measure parameters seismic, environmental, and hydrological applications. Analyzing response often requires properties areas that have little or no data. Therefore, given limited data, it is critical to understand how accurately estimate soil at unsampled...

In this article we explore whether a strong earthquake (Manabí and Esmeraldas provinces, Ecuador, April 16th, 2016) had distributional effect in labor income. We use survey micro-data exploit the exogenous nature of shock with an empirical strategy based on combination matching, difference (DID) quantile regression (QR) methods using three intensity measures to define our treatment group (Peak ...

Abstract Natural disasters may lead to failure of critical assets part railway systems. Slope often results in major economic consequences. Due the importance that railways systems have, it is pertinent ensure good performance and long‐term. The objective present research propose tools allow obtaining probability soil slopes under a seismic event by employing surrogate models ease computational...

In this study, an attempt is made to generate hazard maps for the Jammu Region (JR) in and Kashmir terms of surface peak ground acceleration ( $${\mathrm{PGA}}_{\mathrm{surface}}$$ ), liquefaction zonation, vulnerability index $$K\mathrm{g}$$ ). To do this, seismic response 200 sites was examined, amplification factors at 0.01 s, 0.2 1 10 s were estimated based on site-specific $${\mathrm{PGA}}...

An attenuation relationship model belonging to a region with high earthquake hazard is important. It used for engineering studies know how the peak ground acceleration (PGA) value depends on distance where there are no stations. This study earthquakes magnitudes greater than 4 that IzmirNET recorded between 2009 and 2017 determine PGA through an artificial neural network (ANN) adaptive neuro-fu...

This paper presents a methodology for probabilistic hazard assessment for the multihazard seismic and tsunami phenomena [probabilistic seismic and tsunami hazard analysis (PSTHA)]. For this work, a full-rupture event along the Cascadia subduction zone is considered and the methodology is applied to a study area of Seaside, Oregon, which is located on the US Pacific Northwest coast. In this work...

Past earthquakes have demonstrated that old RC bridges may be seismically vulnerable. Bridge responses during the last decades illustrated the necessity of the seismic assessment of bridges especially those which were designed with old codes. In this research an existing concrete bridge representative of the most common bridges in the highway system in Iran are studied. Push over and nonlinear ...

Damage status of RC buildings is greatly influenced by the characteristics of the imposed ground motion. Peak Ground Acceleration and frequency contents are considered the main two factors that affect ground motion characteristics; hence, affecting the seismic response of RC structures and consequently their damage state. A detailed investigation on the combined effects of these two factors on ...

The assessment of seismic performance of existing structures is becoming an important problem in earthquake engineering. Some important ructures are considerably old and, therefore, their strengths and ductilities are less than strength and ductility demands because of changes in codes and design methodologies. Such structures must be strengthened to resist future earthquakes. First, a structur...
