according to development of displacement–performance based design, there are some studies on different structures which most of them are about regular plan structures. in this research has been tried to review the frame steel structures designed based on 2800 standard of iran to achieve the designed structures performance level to find how much function levels it covers in earth quake. to show ...

in this study, for evaluating ductility of ordinary concentrically braced frames (ocbfs) and special concentrically braced frames (scbfs) which are x- braced in two adjacent middle spans, 16 steel ordinary concentrically braced frames and 16 special concentrically braced frames are studied. the results confirm that, although most of ordinary concentrically braced frames, which are x-braced, can...

sReceived 11 February 2005; accepted 27 April 2005; published online 20 June 2005d Bright green electroluminescence with luminance up to 2800 cd/m2 is reported from indium-tin-oxide/SiO2:Tb/Si metal-oxide-semiconductor devices. The SiO2:Tb 3+ gate oxide was prepared by thermal oxidation followed by Tb+ implantation. Electroluminescence and photoluminescence properties were studied with variatio...

More research is needed before we know the implications of climate change for Australian farms. Nevertheless given the information at hand, an assessment can be...

Avoidance tests with collembolans provide a quick assessment of soil quality. However, some parameters of the procedure can be modified in order to increase its performance. In this study we assessed the tendency of Folsomia candida to avoid soils contaminated with boric acid [350-700-1400-2800-5600 mg/kg soil dry weight (dw)], phenmedipham (35-70-140-280 mg/kg dw) or petroleum hydrocarbons (13...

We present a code that calculates the relic density of the lightest supersymmetric particle (LSP) in the minimal supersymmetric standard model. All tree-level processes for the annihilation of the LSP are included as well as all possible coannihilation processes with neutralinos, charginos, sleptons, squarks and gluinos. In all we have included over 2800 processes not counting charged conjugate...
