Inelastic behaviour of reinforced concrete frames Available to Purchase

The paper presents the results of tests on eight two-bay closed rectangular frames tested to destruction under different sequences of loading. In most cases, plastic hinges formed leading to the formation of collapse mechanisms. Under sway loads, the shear forces were higher and in some cases unexpected shear failures occurred. It is shown that the sequence of live loading is a major influence upon inelastic rotational capacity of a plastic hinge in a frame. Various methods of analysis and design are considered and design recommendations are given.
