Quasi-nonlinear stability analysis of R/C structures

This paper presents a simple method for determining the bearing capacity and stability of linear reinforced concrete structures and frames significantly exposed to compressive loads. The quasi-nonlinear method is based on the linear static analysis used to determine the section forces, while the buckling length is determined by using a geometrically nonlinear analysis or approximate methods common in engineering practice. These results are introduced into the spectrum of the bearing capacity to determine the failure compressive force for each element. The bearing capacity spectra are non-dimensional graphs developed by numerical experiments with a material and geometrically nonlinear model. The efficiency of this method has been illustrated by the solution procedure of few examples.
