Study on the mechanical properties of beam-column structure made of larch plywood

摘要

Beam column is an important structure of a building, and its mechanical properties can directly affect the quality of buildings. The traditional wooden beam-column structure has defects in quality and dimension; to avoid the defects, laminated wood emerges. To prove the mechanical properties of plywood beams and columns, the three-layer plywood beam-column structure was made using larch wood and taking melamine resin as adhesive. The beam-column structure was divided into three groups, group A, B and C, 5 each group, for compression resistance, bending resistance and ultimate load tests. The results showed that the larch plywood beam-column structure had favourable compression and bending resistance and had an ultimate load which was close to the theoretical one, but was slight small. To sum up, the beam-column structure which was made of the three-layer larch plywood that is glued using melamine resin has good mechanical properties.
