A model for the analysis of elasto-plastic buckling of compressed columns
Apstrakt
Modern structures often use new technology materials as special high-strength steels. This is
one of the reasons why cross-sections of structural members are smaller and structures are lighter
than those built fifty years ago. Besides, there are new calculation methods that try to optimize
material use and save money. Engineers today are faced with new challenges in terms of the
design and construction process. Structures are often very slender and can be prone to loss of
structural stability.
The most common example of such a slender element is column. They are often subject to
compression loading so stability can be a significant factor in element design. To build safe
structures with optimized material use, it’s very important to have a clear picture of element
behavior in the pre-buckling and post-buckling phases. The nonlinear analysis could be very
complex even for simple structures and because of that, different software is to be used for such
tasks. In this paper, a ...
