Technical Abstract
A 'finite element structure', which models the observed behaviour of plastic hinge zones of reinforced concrete frame structures, was developed and implemented into a nonlinear dynamic computer programme.
A series of static and dynamic analytic tests were then carried out on a number of reinforced concrete frame structures to assess the performance of the hinge structure, the magnitude of the elongation arising in the beams and the effects of this elongation on the response of the structures.
