Background: Stiffened plates are commonly used in many engineering applications. Engineers
in practice encounter many challenges in the analysis and design of stiffened plates due to the
modelling complexities and many parameters involved. Little guidelines are available in industrial
codes of practice for the design of stiffened plates. This article reviews recent developments and
patents related to analysis and design of thin walled stiffened steel plates. Various numerical procedures
used for static and dynamic analysis are reviewed. Engineering Patents describing various cost
effective fabrication procedures are briefly discussed.
Objectives: The paper illustrates the behaviour of stiffened steel supports under static and dynamic
loadings. Design guidelines are presented that can be utilized in practice.
Method: The potential energy is expressed in terms generalized functions that describe the displacement profile. The resulting
non-linear functions are minimized with respect displacement coefficients.
Results: Numerical results are presented to highlight the essential parameters that need to be considered in the design of
transversely stiffened panels. Influence of the web and flange geometrical sizes on the stability of stiffened supports are
also illustrated. Design curves are provided that can be utilized in the industry to optimize the design of stiffened steel
Conclusion: It is shown that the number of longitudinal stiffening configuration largely influence the magnitude of the
natural frequency and the buckling coefficients. The results are very useful and can be utilized in the industry very effectively
for the steel supports.
