Examples verbs name year Since Yao (1972) firstly proposed/claimed/believed the concept of structural vibration control, a series of energy dissipation mechanical devices and dampers, collectively known as the structural protecting system, have been developed. MYDs, proposed by Kelly (1972) were initially introduced as passive control devices in structural engineering. Silva (2004) proposed a total probability formula in the frequency domain to calculate the dynamic response of a highway bridge. In this regard, the classic continuum model for the linear vertical vibration of suspension bridges, based on the so called linearized deflection theory, was first proposed by Bleich et al . (1950) , and Steinman (1935) , who derived some formulas for computing natural frequencies and mode shapes, and recently reviewed by Luco and Turmo (2010 ) .
