Document Type: Journal Paper


Response of a uniform clamped-free beam driven into the inelastic range by half-sine, triangular, and rectangular ground acceleration pulses is investigated. Shock spectra are presented for beams possessing bilinear moment-curvature properties. Limited data are presented for a supported-supported beam. Beams are represented by lumped parameter models and equations of motion are solved on an analog computer. Effetcs of pulse shape and duration are evaluated.
