This research examines the deflection characteristics of layered timber/steel composite beams with hopes of applying such principles to large timber structures such as highway bridges. Basic theory is developed and testing is performed on timber beams with steel cover plates to find a correlation between theoretical and actual deflections. Although shear stresses can sometimes control these types of beam designs, studies for shear are not included in this research.
