Resposta dinâmica de estruturas reticuladas a cargas móveis, pelo método dos elementos finitos

Abstract

Studies the dynamic behavior of framed structures under moving loads by means of the finite element method. Three different types of loadings are idealized and impact factors determined for them, being developed computer programs for dynamic analysis of beams and plane frames. The structure-loading equations of motion are formulated in matrix form and solved directly through step by step integration. The results are presented in dimensionless form, relating impact factor to travel time for the most usual moving load cases.
