What is it about?

Two regression formulas are proposed to estimate, given the spectral displacement at the fundamental period T, the roof displacement and IDRmax as a function of the building height and the infills opening percentage at first and upper stories.

Why is it important?

The proposed expressions could be used for the simplified evaluation of the expected drift demands for buildings of existing RC typologies.


The proposed formulations are applied to a number of permanently monitored buildings, comparing the calculated IDRmax with the one resulting from record processing, obtaining a fair good agreement
