To date, considerable work has been done on the mechanical properties and behavior of steel fiber reinforced concrete (SFRC) beams.
Factors Affecting Shear Strength Studies documenting the factors influencing the shear strength of high-strength SFRC beams have been extensively reported in literatures.
The increase in shear strength attributed to the interaction between the steel fibers and the concrete matrix is complex, and many factors were investigated and found to have an effect on the beam shear strength.
However, the widely accepted important impact factors are the concrete compressive strength (ƒc), the tensile reinforcement ratio (ρ), the span-depth ratio (a/d), the fiber aspect ratio (lf/df) and the amount of fiber in concrete (Vf).
The factor is shown as follows:

In conventional method, the strength design of steel structure is usually determined by using a safety factor where in design phase will influence its weight [3,4,5,8].
Futher analysis of of energy equilibrium between works done by virtual displacement of applied loads and energy dissipating in plastic hinges of the mechanism during deformation (Wext=U) will result in the expression of plastic load carrying capacity (Pp) as follows : Pp= -1+12+4(B1+B2)(C.A+C.A2)2(B1+B2) (8) C=2b[bC1+ 2bh + 4r +0,5tC2] , A=2σyt2C6C7 , a1=synt , A2= syt2D C3+C4e +0,5C5 , B1=C.Aa12 , B2=C.A21,5hpC2syC82 Experimental Approach The experimental approach was performed in two steps, which consisted of tensile test to assess mechanical properties of the basic material (Standard JIS Z 2201 No. 13A) and interaction of concentrated-compressive load and bending moment tests on 12 specimens of SHS beam.

Studies have shown that the occurrence of algal blooms are closely related with nutrients, temperature, light, and other organism’s factors[1].
Yamamoto et al.[2] discovered that algae blooms was affected by water flow in field investigation, Hosaka et al. [3] found that the appropriate shear rate could increase the growth rate of Chlorella, therefore, water flow was the important causing factor for the growth of algae.
Microcystis aeruginosa growth in autumn and early summer raw water were quite different at different flow rates, the biomass of Microcystis aeruginosa in autumn raw water was significantly higher than that in the early summer under fluid motion, it showed that autumn raw water was more conducive to the growth of Microcystis aeruginosa, TN and TP concentrations in raw water medium was similar, so this may be related to the medium properties.

Bubbles exist inevitably in natural water because of the flow, waves, mechanical agitation, change of pressure, biological photosynthesis and other reasons.
The main factors affect the diffusion velocity are the variety of gas, the solute concentration, the variety and proportion of surfactant, area of gas-liquid interface, and the physical condition such as temperature and flow disturbance, etc.
The initial radius r0 and number density ψ of IGN were set artificially to present different property of DEF.
However in this paper, the numerical calculation is limited to factors r0 and ψ.
Other factors in DEF expansion model will be analyzed in our future work.

© 2003 Trans Tech Publications, Switzerland Material Removal Mechanisms in Diamond Grinding of Granite, Part 3: Factors Influencing the Formation of Surface Gloss H.
Gloss readings increase with the decrease of the diamond grits size, which is the most important factor governing the gloss readings of the granite surface.
The workpiece materials were three typical natural granites, the properties of which were also presented in Part 1.
Therefore, the diamond grit size is the important factor governing the gloss readings of the granite surface.
Gloss readings increase with the decrease of the diamond grits size, which is the most important factor govering the gloss reading of the granite surface.

Due to the particularity of the application situation, there are high demands for the uniformity of its mechanical properties and the type and content of microstructure.
The comprehensive mechanical properties of steel can be improved by controlling the rolling process parameters and cooling process conditions reasonably [19-21].
As a result, the microstructure and mechanical properties of these parts differ from the surface.
At this rate, the microstructure is extremely detrimental to the mechanical properties of 20CrMnTi experimental steel, and enterprises should avoid such structures in the production process.
Furthermore, these factors also have a strong effect on Vickers hardness and tensile strength.

Due to the complicated nature of fatigue mechanisms and the large number of factors that influence fatigue life, there is so far no unified approach that can treat all fatigue problems [1].
Geometry of component and load conditions are the two dominant parameters which will affect the mechanism of failure and crack propagation.
