EFFECT OF DIFFERENT JOINING METHODS ON SKIDDING DEFORMATION OF DIAGONAL MEMBER BY DIAGONAL AXIAL LOAD IN SAWN TIMBER TRUSS : MECHANICAL ANALYSIS USING SPRING MODEL

This study attempted to clarify the sliding behavior that occurs at the diagonal joints of wooden truss beams. Specimens were created in which the diagonal members, bottom chord members, and beams were joined in different ways, and diagonal member axial load tests were conducted to verify the relationship between load and displacement. Factors that affect deformation were extracted as spring elements, and the initial stiffness was calculated taking into account the generated frictional force, and the calculated values were compared with the test values.
