Thin walled Steel products are very much used in the construction industry, where it
is cold formed from uniform thickness steel plates. This study aims at determining the
optimal section of cold formed thin walled lipped C compressed member under
the effect
of several levels of axial force using Genetic Algorithm.
The research found that the genetic algorithm is able to resolve the issue of the
optimal design of studied column with high efficiency, accuracy. Also it found that the
torsional flexural buckling constraint and the overall buckling constraint in x-direction are
the effective constraints in case of long height.
The study recommends restudying the same issue as a multi objective optimization
problem by adding additional objective functions which are the overall buckling in x&y
directions.
Esthetic orthodontic archwires (fiber reinforced composite archwires) are
considered as the latest addition to orthodontic's world, and the load deflection rate is thought to be the
most important mechanical property of archwires which has strong e
ffect clinically, and this property is
affected by the cross section diameter and the material's type, for these reasons this study aims to
investigate the effect of the material's type and the cross section diameter of orthodontic archwires on the
load deflection rate of fiber reinforced composite(FRC) archwires with a diameter of 0.014 inch and
0.016 inch which are suitable for the leveling and alignment stage, and to compare these new materials
with Nickel titanium(NiTi) archwires .
Cold formed steel (CFS) has many advantages over other construction materials.
CFS members are lightweight. They weigh up to 30-35% less than their wood
counterparts.. This makes CFS members economical and the same time very easy to erect
and inst
all. They may be shaped (cold-bent) to nearly any open cross section. This allows
for the use of optimization technique’s to find optimal shapes for the members’ cross
sections.
The research aims to show the genetic algorithm's ability in determining the optimum
dimensions cold formed C section. To do so, the optimum design mathematical
formulation was formulated by adding the manufacturing constraints that reflect the
section folding operations in addition the geometrical and structural constraints.
The research found that the genetic algorithm is effective tool in finding the best
solution to this issue, as it showed its ability to deal with asymmetric section through
reaching solutions conform to the basic principles of mechanics of material.
The algorithm is adjustable, so that it can implement the design restrictions which are
compatible with any codes or any manufacturing requirements imposed by modulation
techniques.
This paper presents structural
analysis in using ANSYS programme for modeling of heat load then
comparison between the analytical results and experimental results is
performed .
In this research, we discussed an analytical
study of the seismic behavior of an internal joint, and we improved
the plastic response of the joint after observing the effect of the
concrete encasement to the column’s steel section along the
connection area.
