The aim of this study was to clarify the effects of forest management such as pruning and thinning on the visual grading and bending properties of boxed-heart square timbers of sugi (Cryptomeria japon...
Rational Timber Frame Structure Jointed with Glass Fiber Reinforced Nylon Plate II.Strength properties of drift-pin joints under static loading
GFRP drift-pin timber joint tension resistance shear resistance
2009/11/23
A new drift-pin joint consisting of a glass-fibre-reinforced nylon (GFRP) plate inserted into a slit of the timber with steel pipe drift-pins was designed. In the previous report, basic shear properti...
Static and impact bending strength properties of aged keyaki and akamatsu woods
aged wood strength properties bending test impact bending test
2009/3/6
Mechanical properties, namely modulus of rupture (MOR), modulus of elasticity in bending (MOE) and impact bending strength, were measured with small clear test specimens of new and aged wood. The test...
Effect of metal lath-staple joints on strength properties of mortar walls
conventional wooden structure external finishing mortar wall staple joint earthquake resistant design
2009/3/5
In the last report, we proposed an analysis method for the deformation and shear resistance of mortar walls. This report tried to improve the analysis method discussed before by means of providing a n...
