Reassessment of Minimum Facilities Wellhead Platform due to Installation of Extension Compressors against Earthquake Loads

Extension of Excavation Damaged Zone Due to Longwall Working Effect

In advance longwall mining, the safety of mine network, production rate, and consequently, economic conditions of a mine are dependent on the stability conditions of gate roadways. The gate roadway stability is a function of two important factors: 1) characteristics of the excavation damaged zone (EDZ) above the gate roadway and 2) loading effect due to the caving zone (CZ) above the longwall w...

Investigation of Inclined Retaining Walls (Located on Slopes) Performance against Static and Earthquake Loads

DISTORTION OF PLASMA DUE TO INSTALLATION OF AN ORIFICE IN HELIUM DISCHARGE POSITIVE COLUMN

Complicated potential structure formed at a constriction of positive column of a DC discharge with heated cathode in He at low discharge currents is investigated. According to the potential structure, electrons and ions are accelerated by the electric field and their energy distribution functions acquire multi humped shapes. Additional maximums on distribution functions quickly disappear due to...

Analysis of Tall Buildings with Bundled Tube System Subjected to Wind and Earthquake loads

At present, the tubular structural systems are mainly used in tall buildings to withstand earthquake loads. Although it is possible to analyse the structure by finite element methods using standard three dimensional programs, the system is generally time-consuming and expensive in the primary design work. In this paper, for the analysis of Framed-Tube systems, a simple method was studied and de...
