8B. ANALYSIS PART 2

CHAPTER 8B 'ANALYSIS' 122 • Control at operator level This check is for the whole carrier and compares the movement dm which is the movement corresponding to the last step of the pushover With the targeted movements corresponding to the performance levels. EXAMPLE : In this example the value is dm=8.24 cm. This is the maximum displacement that the carrier can withstand before it collapses. This is compared to the target displacement of each performance level dt and must of course be greater, i.e. the requirement (target) must be less than the "resistance".
