Maximum peak interstory drifts

Then the objective function, representing the maximum of all peak interstory drifts, can be defined as... 

A laiger dispersion of drifts occurs in the damped flame under the MCE, with an average of 0.39% maximum standard deviation, with all methods within 11% of the average maximum standard deviation. The dispersion is laigest in the internal floors (2-7) corresponding to the largest peak interstory drifts in the frame. 

Table 4 presents the maximum interstory drifts of all floors. The uniform and stiffness-proportional damper schemes produce very similar maximum interstory drifts, while the three advanced techniques all result in lower peak drifts,... 

Peak transient interstory drift ratio (PTD). This is the maximum value at any time during seismic excitation of the displacement of the floor above relative to the floor below the story on which a component is installed, divided by the height difference of the two stories. "The displacements are commonly measured parallel to a horizontal axis of the component, such as along a column line.
