A measure of earthquake motion capacity to damage medium-period structures
The expression I=vgtD0.25 is proposed as an instrumental measure of earthquake ground motion capacity to damage structures with fundamental periods in the medium-period (velocity-controlled) region. Only two of the basic ground motion parameters which can be routinely predicted in the design procedure (peak ground velocity and the duration of strong shaking) are included in the formula. Expressions for determining the bounds of the medium-period region are also proposed as a function of the basic ground motion parameters. A total of 40 records having very different characteristics, including extremely short and long duration, were used in the statistical study. The new intensity parameter has been evaluated by using inelastic and elastic relative displacement and input energy spectra.
