DETERMINING INTERSTOREY DRIFT CAPACITY OF R/C FRAME BUILDING
In most current seismic codes the criterion of whether the performance objective for a certain level of behaviour has been met is usually given by means of seismic response parameter defined at the level of the storey such as the maximum inter-story drift ratio IDRmax. On the other side, in order to estimate the colapse state for structures exposed to strong earthquake motions which apart from the elatic domain enter also in to the plastic domain of behaviour, it is necessary to know also deformations capacity at the places of plasticity, i.e. capacity of plastic hinges θmax. This paper will show a method of determining capacity IDRmax by means of local parameters of seismic response: plastic rotation capacity, θpu and damage index, DI. The relations between IDRmax on one side and θpu and DI on the other are established by means of non-linear dynamic analyses of 4, 6, 8 and 12- storey RC frames designed according to the EC8.
