Stability analysis of reinforced concrete building frames damaged by corrosion under static-dynamic loading

Abstract

The paper presents a methodic for calculation reinforced concrete frame-braced structural systems, when it was damaged by corrosion, against loss of stability in over limit state caused by removal of a load bearing element. The authors obtained analytical expressions for assessment stiffness of reinforced concrete compressed-bent elements taking in account its nonlinear deforming. Such expressions allow conducting stability analysis of structural systems under consideration.
