Abstract
A computational procedure for predicting the geometric and material no nlinear dynamic response of space trusses is presented. An updated Lag rangian method, based on the incremental formulation of the equation o f motion, is employed. The constitutive law is cast into the Ramberg-O sgood polynomial model. Numerical studies of two- and three-dimensiona l truss structures under various dynamic loading are made. The structu re dynamic response including different types of nonlinearity is compa red with the linear response and with the results obtained from static analysis.
