To study the influence law of effective peak acceleration (EPA) on seismic response soil slope, finite element method was used to simulate slope under earthquake action with 100 actual records were selected, EPA four different definitions commonly in domestic and foreign codes discussed, which compared (PGA). The results showed that deformation maximum principal stress both increased PGA, had a...

Post-disaster reconstruction management of urban areas requires timely information on the ground response microzonation to strong levels of ground shaking to minimize the rebuilt-environment vulnerability to future earthquakes. In this paper, a procedure is proposed to quantitatively estimate the severity of ground response in terms of peak ground acceleration, that is computed from macroseismi...


 Past studies have demonstrated that the vertical earthquake component can substantially affect seismic performance of bridges and buildings. This is typically ignored or, when included in design, estimated as two-thirds horizontal design earthquake. paper presents characterization acceleration amplitude moderate strong earthquakes Colombia (Moment magnitude Mw > 4) occurred between Ju...

The effects of hypo-central distances and magnitude on the acceleration response spectra in this study are based 24 sites Gansu province China, all spread over loess regions. normalized with 5% damping were determined for 106 strong ground motions contained horizontal vertical components, recorded at these ranging from 3.7 to 7.0. It is shown that shape spectrum affected by not only but also di...

The Peak Ground Acceleration (PGA) is extensively used in earthquake engineering practice to describe the ground motion characteristics for establishing seismic vulnerability curves. However, a single parameter not enough excitation and does allow expressing complex relationship between structural damage movement. Motivated overcome these shortcomings, several ANN-based models were proposed pre...

The 1992 Cairo earthquake, with a moment magnitude of 5.8, is the most catastrophic earthquake to shock Greater (GC) in recent decades. According very limited number seismological stations at that time, peak ground acceleration (PGA) caused by this event was not recorded. PGA calculation requires identification nature source, geologic setting path between source and site under investigation soi...

Although some studies have been conducted to compute fragility surfaces of buildings using vector-valued seismic intensity measures (IMs), in all the cases, first component vector usually is spectral acceleration at mode vibration structure Sa(T1). In this study, three reinforced concrete (RCB) subjected narrow-band ground motions obtained from soft soil Mexico City are computed considering IMs...

Kutupalong Rohingya camp is one of the largest humanitarian shelters for conflict-fled people. The area susceptible to landslide hazards because being situated in dynamic tectonic settings and meteorological conditions. Hence, study aims assess earthquake rainfall-induced worst-case scenario. triggering parameters (topographic, soil physical property, contributing factors) are designed identify...

Padang City as the capital of West Sumatera Province is at high risk earthquakes and tsunamis due to its location between two continental plates Semangko Fault. Currently, there are several shelters in that serve evacuation sites a rescue when tsunami hits. This paper presents an earthquake detection system uses distributed sensors activate shelter search system. The proposed will has medium or...

Based on the observed strong-motion records of K-NET and KiK-net, we utilized 1,065 earthquake observation stations installed throughout Japan, gathering more than 140,000 recordings for weak motions with a peak ground acceleration (PGA) less 100 cm/s2 5,300 strong PGA cm/s2. These sites detected at least one recording value greater were used to quantify horizontal-to-vertical spectral ratio (H...
