Abstract
The present research is considered as a survey for the different
methods used in the analysis and design of steel frames, whatever these
methods are elastic, non-linear elastic or plastic analysis.
The research starts with representing the analysis methods used
previously and also represents the different methods used for optimum
design and their classification. The research concentrates especially on the
non-linear elastic analysis of steel frames as this analysis will be used in
the optimum design. The research also reviews the Refined Plastic Hinge
analysis method as it is the method used in this thesis for plastic design
check..
The thesis introduces a method of optimum design considering
stress and buckling constraints, this method uses the moment of inertia as
the design variable.
Different shapes of structural steel frames are analyzed to apply
the analysis and optimum design method. Effect of using the section The thesis analyzes the optimally designed frames using the refined
plastic binge method and get the factor of safety against plastic collapse
for these frames. Finally the research represents the basic results obtained,
the conclusions of this research and recommendations for the future
studies .
