Abstract—
The paper has investigated a difference of flashover phases between extra-high voltage (EHV) and highvoltage transmission lines based on EMTP simulations. The number of ground wires and a tower footing resistance cause a significant effect on the three-phase archorn voltages. A higher probability of a back-flashover across the upper-phase archorn is very noticeable in the case of a tower with two ground wires and a lower f ....etc

Strength based and Displacement Based Design method for steel


Abstract

The performance based seismic design of Steel moment resisting frame structures aimed at controlling the structural damage based on precise estimations of proper response parameters. The primary focus of this study is on the development of a detailed assessment of the inelastic seismic behavior, response, and performance of typical ductile Steel moment resisting frame structures. This research tries to assess the Strength based and Disp ....etc

This article describes the effect of tower displacement of two parallel transmission lines on the magnetic field distribution. Here, two parallel lines with the same working voltage and having the same span and in which the use of artificial tower displacement is made is modeled.Parallel transmission lines with different span lengths and different voltages produce tower displacements naturally and this is also modeled. Additionally, the effects like the spacing between the parallel lines, phase conductors arrangements and the transmission line ....etc

ABSTRACT
Transmission lines are considered one of the major sources of magnetic field. In recent years great public concern has arisen because of reports on adverse health effects due to Magnetic fields. The rapid increase of electric energy utilization and ascending geographical growth in the Gulf Cooperation Council (GCC) region led to the reality that utilities need to upgrade and develop existing and new transmission and distribution lines which resulted in the transmission lines to become inside the urban areas. This project is directed ....etc

Abstract:
This seminar is intended to evaluate the applicability of Nonlinear Static Procedure by implementing the Displacement Coefficient Method to bridges. For comparison purposes, the Nonlinear Dynamic Procedure (or nonlinear time-history analysis), which is considered to be the most accurate and reliable method of nonlinear seismic analysis, is also performed. A three-span bridge of 97.5 meters (320 ft) in total length was analyzed using both the Nonlinear Static Procedure/Displacement Coefficient Method and nonlinear time-history. Nine ....etc

SEISMIC ANALYSIS OF BRIDGES USING DISPLACEMENT-BASED APPROACH

By Chung C. Fu and Hamed AlAyed, University of Maryland

ABSTRACT
Nonlinear Static (Pushover) Procedure is specified in the guidelines for seismic rehabilitation of buildings presented by FEMA-273 (1997) as an analytical procedure that can be used in systematic rehabilitation of structures. However, those guidelines were presented to apply the Displacement Coefficient Method, which implements the well-known equal displacement rule with some modifications to est ....etc

Abstract
The purpose of this paper is to investigate using a numerical simulation (computational fluid dynamics or CFD) the effect of the air supply location on the design and performance of the displacement ventilation (DV) system. The results are reported in terms of thermal comfort and indoor air quality. The study focuses on a typical enclosure in CBIT under local thermal and boundary conditions. This includes several pollutants typically found such as carbon-dioxide and volatile organic compounds (VOCs) were inv ....etc
