7.7 The SDOF system shown below is supported by a 10 ft diameter circular footing. The mass of the footing is small compared to the mass of the structure. Compute the damped natural period of the soil-structure system: (a) assuming fixed base conditions, (b) assuming that the footing can translate horizontally (but not rotate), and (e) assuming that the footing can both translate and rotate. w 100k k= 10 k/in C = 160 lb-sec/in 10 ft 10 ft V, 750 ft/sec v=0.33 y = 130 pct Figure 17.7
