Closed-Form Formulations in Composite Beams Based on Partially-Composite Behavior

Partially-composite beams are composite beams with a more complex behavior which includes fully-composite to non-composite behaviors. Hence, fully-composite and non-composite behaviors are considered as boundary conditions of partially-composite behavior in this paper. Two new closed-form formulations for slip and flexural rigidness calculation of non-composite and fully-composite beams are obtained respectively, and their results are compared with the conventional methods. Results of the current paper shows that the presented closed-form formulations have the same results with the conventional methods and can be conveniently used in the analysis of composite beams.
