| Abstract | Glued box beams with hardwood flanges and plywood webs were constructed with various thicknesses of web and were tested by third point loading on a 2.10 m span. From the load-deflection curves and analysis of results, it is shown that a suitable limit for the working load of the box beam would be when the central deflection of the beam was L/360. In the design of such box beams the buckling of web members is a very important factor, since the effective adhesive strength of glue is reduced by tensile stress in the glue line due to cleavage action. This buckling effect may be reduced by increasing the thickness of web members. Resorcinol and PVA glues are strong enough to be used as the connecting medium between hardwood flanges and plywood webs of box beams. |
