dc.description.resumo	This paper analyzes the dynamic response of space and plane trusses with geometrical and material nonlinear behaviors using di®erent time integration algorithms, considering an alternative Finite Element Method (FEM) formulation called positional FEM. Each algorithm is distinguished from each other by its speci ̄c form of position, velocity, acceleration and equilibrium equation concerning the stability, consistency, accuracy and e±ciency of solution. Particularly, the impact problems against rigid walls are analyzed considering Null-Penetration Condition. This formulation is based on the minimum potential energy theorem written according to the nodal positions, instead of the structural displacements. It has the advantage of simplicity when compared with the classical counterparts, since it does not necessarily reply on the corotational axes. Moreover, the performance of each temporal integration algorithm is evaluated by numerical simulations	pt_BR
