RESUMO:

Steel structures are generally designed for industrial and commercial buildings, since they have high strength-to-weight ratio and excellent ductility. Such a constructive system has high slenderness ratio and lightness, and, therefore, it is necessary its structural verification considering dynamic actions and second order effects. During the design phase, analyzes are performed to obtain the structure responses and to design structural elements. Through computer programs, results more consistent with the real behavior of the structures have been obtained. These software programs using advanced analysis methods are able to consider simultaneously different causes for the nonlinear behavior of the structure as well as different types of loading, resulting in a less conservative design. In the case of structures subjected to dynamic loads, these analysis techniques become even more necessary, since the internal forces can cause permanent deformations and localized damage to the structure. The objective of this research is to present a study of the dynamic behavior of plane steel frames,  through time-domain integration, considering the physical and geometric nonlinearities. In order to solve the nonlinear transient equations, it will be implemented in the PPLANLEP program the Newmark's implicit time integration method combined with the Newton Raphson technique. Numerical examples are presented to verify the accuracy and efficiency of the proposed method in obtaining the nonlinear dynamic behavior of steel structures.
