Abstract

In most countries, the post-beam wooden building construction method is the oldest architectural style, similar to the Korean traditional building (Hanok). In this study, numerical analysis was performed to evaluate the bending performance of the Joomeokjang joint (J-joint) and the Nabijang joint (N-joint), which are the most widely used in traditional Korean wooden frame constructions. To examine whether it is possible to grasp the bending properties of wooden structural components, a structural sized specimen without joints was investigated first. To ensure accurate application of the numerical analysis method, the 3-D orthotropic elements were evaluated and the results confirmed the viability of the method. Subsequently, we confirmed the applicability of the numerical analysis by comparing the results of the actual bending performance test and the finite element analysis results for the J-joint and N-joint. Stress concentration and deformation similar to the actual fractured specimen were observed with finite element analysis. As a result, by applying FEM without destruction of the joint, which is uneconomical and inefficient, we will be able to ascertain the strength of various types of joints in the future.
