Analysis Type(s): Mode-frequency, Seismic Analysis (ANTYPE = 2) Element Type(s): 2-D Elastic Beam Elements (BEAM3) Input Listing: vm70.dat Test Case 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.
