in fact the most suitable method for finding the load bearing capacity of a member under the axial load or axial load and bending is make use of the interaction diagrams. to analysis and design the hollow circular, square and rectangular high strength concrete (hsc) column shapes, a linear strain variation was assumed in the cross-section height of the members and then the static equilibrium eq...

Abstract Effect of convection on the distortion spatial self-phase modulation(SSPM)pattern in graphene dispersions has been investigated. When a Gaussian laser beam is transmitted through grapheme dispersions, interference pattern far-field first forms series circular rings, but upper half rings collapses rapidly after period time, forming stable distorted pattern. Experimental results show tha...

--Most of the structures in flowing water are a challenge to their stability and sustainable with different flow conditions. Recent, renewable energy research and development covers ocean and river energy platform in which flow of water drag considered in various conversion devices towards the offshore and onshore establishment. Various energy platforms have been suggested for offshore developm...

The acrosswind response of isolated reinfe~c~d concrete chimneys of circular cross-section is studied using wind tunnel tests, full-scale measureme,~ts and response predictions based on semi-empirical methods. Three chimneys with available full-scale response observations were selected for this study to compare their measured and predicted responses. The wind tunnel experiments involved measure...

The one-step stair-shaped dielectric resonator antennas (DRAs) with a circular cross-section are studied theoretically and experimentally in this paper. The reasons why the one-step stairshaped DRAs have a wideband performance have been investigated. It is shown in this paper that the modes excited in the one-step stairshaped DRA with circular cross-section can be regarded as pseudo HEM111 and ...

This paper presents a numerical computation method for determining the magnetic field of high-current busducts of circular cross-section geometry, based on the subdivision of the busduct phase conductors and screens into the conductor filaments and the subsequent application of the mesh-current method, with the aid of the geometric mean distance method. The mathematical model takes into account...

Pressure driven steady flow through a uniform circular channel containing a constricted portion is a common problem considering physiological flows such as underlying human speech sound production. The influence of the constriction’s cross-section shape (circle, ellipse, circular sector) on the flow within and downstream from the constriction is experimentally quantified. An analytical boundary...

We have experimentally investigated the anisotropy-dependent circular polarization spectra of the Cs 6sS1/2→6p P3/2→10s S1/2 double-resonance transition in the presence of Ar. Satisfaction of doubleresonance condition, achieved by use of a two-photon two-color pulse laser excitation scheme, was monitored by measurement of the intensity of the 9pP1/2→6s S1/2 cascade fluorescence at 361.73 nm. In...

A computationally efficient method for generating virtual periodic representative volume element (RVE), capable of handling arbitrary inclusion shapes, is developed. universal collision/overlap detection and repair proposed, where each shape represented as a union n-Spheres (UnS). constrained optimization problem formulated solved to remove overlaps; closed-form solution derived calculating the...
