The average value of the power Pave is (2.112)Pave=1T∫Tpdt=1T∫Tν×idt If the voltage across and the current through the resistor is sinusoidal with a peak value of V⌢ and I⌢ respectively, then v=V⌢ sin ω t and i=I⌢ sin ω t and so (2.113)Pave=1T∫TV⌢sinωt...
Present design response spectra display the maximum value only of the response of a linear single--degree-of~freedom (SDOF) oscillator and hence ignore information on the duration of the response and the effect of the amplitudes of the lesser but near maximum peak values of the response time ...
