optimization of structures for minimum weight has become important in the recent designs. in this study, a genetic optimization algorithm for weight minimization of steel frames has been used. the genetic algorithm is an optimization and search technique based on the principles of genetics and natural selection. constraints regarding material strength and serviceability are taken from “aisc cod...

Abstract Lateral forces (wind, seismic) generated in RC buildings are major design criteria against structural collapse. Shear walls offer effective ways to provide resistance such lateral loads. The present study investigates the drift and defection control of symmetrical by providing core corner shear walls. Different limiting were determined four seismic zones (Zone-1 Zone-4) Bangladesh, bas...

erosion by wind is one of the most important factors in desert environment. prevailing winds can shift sand dunes and affect their accumulation. also, wind regime determines the direction of sand dune mobility. the aim of this research was to investigate sand drift potential using sand movement models. for this research, wind data between 1986 and 2005 from the meteorological station of yazd we...

Seismic record of an earthquake contains important and significant data about characteristics of a ground motion. In this study, interdependencies between important seismic parameters and three overall structural damage indices including the Bracci index, the modified flexural damage ratio (MFDR) index and the drift index were determined for several records of earthquakes occurred in the Iran. ...

Spray drift is a great concern because of environmental consequences of agricultural practices. Many studies were conducted in wind tunnel (Miller, 2011; Nuyttens, 2007; Herbst, 2003) mainly focusing on the definition of quantitative deposition on collectors at different distances or heights according to (ISO 22856, 2008). In most cases, only one nozzle positioned frontally (wind direction perp...

Assuming a vacancy-mediated diffusion, continuum model for electromigration-driven transport of an embedded atom cluster across surface terrace phase-separating A$_x$B$_{1-x}$ alloy, such as fcc AgPt(111), is presented. Computations show that the electron wind carries over hundreds lattice spacings and in set direction, while grows its purity improves during drift. Impacts current density, diff...
