A simply supported beam of length , mass per unit length m, and section properties shown below is subjected
to a vertical motion of both supports. The motion is defined in terms of a seismic displacement response spectrum.
Determine the fundamental displacement δ, and the corresponding maximum bending stress σmax. Figure 70.1 Beam Structure Problem Sketch Material Properties
