Zusammenfassung:CLT is a structural material laminated and glued such that grain directions are orthogonal to each adjacent layer. Since CLT has an orthogonal layer, it seems that there is a possibility that buckling properties differs from lumber and glue laminated timber. It is not certain whether calculation formula of buckling strength used for lumber or glue laminated timber can be applied to the calculation of buckling strength of CLT. In this study, the calculation formula of buckling strength of CLT was proposed and the validity of the formula was examined.
