The present paper describes an analytic solution procedure for flexural vibration of a rotationallyrestrained hinged-hinged Timoshenko beam at the supports during an earthquake. Focusing on maximalmagnitudes of internal loads such as bending moment and shearing force under wide variations of twoparameters, kL=EI and kGAL2=EI, various beams under synchronous and asynchronous support motionsare simulated. The simulations under asynchronous support motions show the following facts. Thevariations of the maximal magnitudes of internal loads of stocky beams due to the variation of kL=EI fromzero to infinity show much wider variations than those of slender beams as kGAL2=EI decreases. Themaximal magnitudes of internal loads of a beam tend to be governed by their static components as kL=EIincreases and kGAL2=EI decreases. When the internal loads are governed by their static components,maximal magnitudes of internal loads of the stocky tend to increase monotonically as the value of kL=EIincreases. However, the simulations under synchronous support motions show the static components ofthe internal loads vanish and the internal loads are governed by dynamic components irrespective of thetwo parameters.
