Wood-Concrete and Wood-Wood Mixed Beams: Rational Basis for Selecting Connections

Resumen

Many studies have approached the problem of mixed beams with a slip at the connection. An analysis of the problem has been carried out globally and Eurocode-5 solves the problem for the use of simple supported beams or similar structures in a precise way and with a simple formulation. Other methods to solve the structural analysis of this issue include matrix as well as several finite-element procedures. Nevertheless, the design process for selecting the connection is now iterative and the variables of the problem can be presented in a more condensed and useful way. The problems of strength and stiffness in this research have been separated. Variables in a powerful nondimensional way and their exact relationships in simple supported beams are presented here. These variables show the nature of the problem in a clear way, and provide a rational basis for selecting the connection.
