IMPLMENTAÇÃO DE CONEXÃO SEMIRRÍGIDA EM MODELOS RETICULADOS NO CONTEXTO DA PROGRAMAÇÃO ORIENTADA A OBJETOS

Resumo

This work presents the implementation of a methodology to simulate semi-rigid joints in two

and three-dimensional framed models using the Direct Stiffness Method. The idea is to add a linear-
elastic rotational spring to the structure by inserting new degrees of freedom to the system of equilibrium

equations to account for the spring rotations. This implementation was incorporated to the LESM
(Linear Elements Structure Model) program, which is an educational open-source program. This
program is based on the Object Oriented Programming (OOP), which was used in order to handle the
problem in a generic fashion. A new class in the context of the OOP was created to simulate the behavior
of semi-rigid joints.
