The objective of this study was to quantify the effects of ground surface motion on the biomechanical responses of a person performing a lifting task. A boat motion simulator (BMS) was built to provide a sinusoidal ground motion (simultaneous vertical linear translation and a roll angular displacement) that simulates the deck motion on a small fishing boat. Sixteen participants performed liftin...

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...

On-site earthquake early warning techniques, which issue alerts based on seismic waves measured at a single station, are promising, and have performed quite successfully during some damaging earthquakes. Conventionally, most existing techniques extract several P-wave features from the first few seconds of after trigger to predict intensity or destructiveness an incoming earthquake. This type te...

Probabilistic seismic hazard analysis (PSHA) has been recognized as a reasonable method for quantifying threats. Traditionally, this ignores the effect of focal depth, in which ground motion prediction equations (GMPEs) are applied to estimate probability distribution associated with possible levels induced by site earthquakes, but it is limited unclear geological conditions, makes difficult pr...

The present study initially selects twenty-one bridges with lengths over 500m in the Formosa freeway of Taiwan, and collects a series of recorded seismic data from checking stations near these bridges. Then, three seismic parameters including focal depth, epicenter distance, and local magnitude, are used as the input data sets, and a model for estimating the key seismic parameter peak ground ac...

Fuzzy logic techniques have been widely used in civil and earthquake engineering applications in the past four decades. However, no thorough research studies were conducted to use them for deriving attenuation relationships for peak ground accelerations (PGA). This paper is an attempt to fill this gap by employing a fuzzy approach with fuzzy sets for earthquake magnitude and distance from sourc...
