Vigas
Abstract in Portuguese
O objetivo do presente trabalho é apresentar tabelas para soluções numéricas de vigas finitas sobre apoio elástico, com diversas condições de extremidade. O modelo de Winkler é utilizado, admitindo-se constante o coeficiente de recalque do solo. As tabelas fornecem os coeficientes de influência para rotações das secções transversais, para reação do apoio elástico, para momento fletor e força cortante. Os coeficientes de influência referem-se a esforços externos, força concentrada ou momento, que se deslocam ao longo da viga. O valor característico SL do conjunto viga-solo varia de 1,5 a 8,0, atendendo portanto as vigas curtas, as médias e as longas. Com referência às vigas sobre apoio elástico, acredita-se que estas são as tabelas numéricas mais completas, disponíveis, no momento.

Abstract in English
The purpose of the pape ris to presente tables for the numerical solutions of finite beams on elastic foundation; several end conditions are included for the beams. Winklers model is assumed, with a constant subgrade reaction. The users are supplied with influence coefficients for slope, elastic foundation reaction, bending moments and shear forces. The influence coefficients refer either to an external concentrated force or to an external moment travelling along the beam. The characteristic value SL, for beam-soil interaction, varies from 1,5 to 8,0, allowing therefore to consider short, intermediate and long beams. Regarding to beams on elastic foundation, we believe the tables to be the most complete numerical ones available at the moment.
