Review article

The article presents theoretical analysis of the performance of composite metal and timber I-beams with a wall of corrugated steel sheet and belts of laminated veneer lumber (LVL). Based on the classical theory of composite timber beams with compliance joints developed by P. F. Pleshkov and A. R. Rzhanitsyn, there has been derived the linear inhomogeneous differential equation of bending of composite beam made of corrugated steel, timber and timber-based materials. There are indicated the modules requiring of experimental determination of their values for this type of structures (namely, the joint stiffness coefficient, the reduced modulus of solid beam elasticity).
