This paper presents a statistical correlation analysis of peak ground acceleration to peak ground velocity ratio (A/V) and other ground motion intensity measures (IMs) for Iran's data. A/V is an important parameter that can significantly affect nonlinear structural responses. Findings from this study provide beneficial insights into selecting suita...

The objective of the present study is to develop and evaluate machine learning-based prediction models, employing the Artificial Neural Networks (ANNs), Genetic Programming (GP), and the Combinatorial Group Method of Data Handling (GMDH-Combi), for dynamic modulus (E*) of hot mix asphalt (HMA) estimation. To develop the models, an experimental data...

The study of earthquake ground motion is a key issue in the field of earthquake resistance. Near-fault ground motions are more severe than other ground motions recorded that occur in the Far- Fault because proximity to the seismic source does not allow considerable attenuation of ground motion. Near-fault ground motion is characterized by its long-...

The main contribution of this study is to open a discussion regarding the structural optimization associated with the cost efficiency and structural reliability sufficiency consideration. To do so, several various optimization approaches are investigated to deliberate both cost and reliability concerns. Particularly, particle swarm optimization is...

According to the recent Earthquake records, the earthquake duration is longer in some areas, resulting into more structural damage. One of the important factors in reducing earthquake damages is the separation gap between two adjacent structures. This case study investigated the effect of significant duration of the earthquake on two adjacent steel...

This study presents new empirical prediction equations for a number of bracketed and uniform durations using the Iranian strong ground motion database of accelerograms for the shallow crustal earthquakes until 2018. The database includes 1147 records of 213 earthquake events with the magnitudes from 5.0 to 7.8 and rupture distances from 2 to 600 km...

In this study, the relationship between different definitions of duration with peak ground acceleration, focal depth and soil conditions of the site using accelerometer records in Iran was calculated and presented. 1054 three-component records of 197 seismic events recorded with a moment magnitude greater than or equal to 5.0 were used. All data fo...

Background and objective: Experience with past earthquakes and numerical analysis confirms that the durability of strong earth motion, significantly can affect the amount of failure of civil engineering systems. However, if the durability is related to a parameter which describes the intensity of the earth's motion, such as maximum velocity or maxi...

Research Aim: The complete characterization of earthquake ground motion includes the length of the interval of strong shaking as well as the amplitude and frequency content of the time series. The experience of past earthquakes and numerical analysis confirms that the durability of strong ground motion can significantly affect the degree of failure...
