Abstract In this paper the site categorization criteria and corresponding amplification factors proposed in 2021 draft of Part 1 Eurocode 8 (2021-draft, CEN/TC250/SC8 Working Draft N1017) are first introduced compared with current version 8, as well from recent empirical ground motion prediction equations. Afterwards, these values checked by two approaches. First, a wide dataset strong records ...

In this research, numerical simulation of a symmetric impact of a 2-D wedge, considering dynamic equations in two-phase flow is taken into account. The two-phase flow around the wedge is solved based on finite volume method and volume of fluid (VOF) scheme. The dynamic mesh model is used to simulate dynamic motion of the wedge, thereby the effects of different dynamic meshes in both structured ...

This paper presents an initial validation of a solar radiation service that provides historical, as well as up-to-the-moment solar resource data from satellites, short-term forecasts from cloud motion analysis, and medium term forecasts (up to seven days ahead) from numerical weather prediction models [1]. Forecasts are validated for several, climatically distinct regions of the US, investigati...

Recent investigations have shown that the influences of Soil-Structure Interaction (SSI) may be detrimental to the seismic response of structure, and hence neglecting this phenomenon in analysis and design may lead to an un-conservative design. The objective of this paper is to quantify the effects of nonlinear soil-structure interaction on the seismic response of a low-rise special moment fram...

the near field ground motions have a high amplitude pulse like at the beginning of the seismogram which are significantly influenced by the rupture mechanism and direction of rupture propagation. this type of ground motion cause higher demands for engineering structures and its response spectrum is dramatically different than far field spectra. tabriz is one of the ancient cities in azerbaijan ...

The characteristics of near-fault ground motion are investigated considering heterogeneous slip distribution on the fault plane. Areas on the fault plane with large slip in compare with the average slip on the fault are known as asperity. The characteristics of strong ground motions in near-fault area are strongly affected by faulting parameters such as asperity location, maximum slip of asperi...

recently a method has been developed to decouple the equations of motion for multi-rigid body systems. in this paper, the method is first studied, then the equations of motion for a planar two degree-of-freedom robot with flexible joints are carried out using lagaranges equations and kanes equation with congruency transformations. finally, the results obtained from both methods are throroughly ...

The aim objective of this study is to investigate the effects of near-field earthquakes on the response of mid-rise buildings with tubular structure.  For this purpose, a 20-story building with a square plan of six by six bays, all with 6 m span, and story height of 3.70 m is considered.  Axial force of columns, shear lag, and inter-story drift values are used as the main response parameters. N...
