Abstract

In this paper, filed measurement and structural analysis were performed syntagmatically to figure out structural characteristics of traditional timber structure. Load cell was installed between column and foundation stone to measure column axial force, and ambient vibration test was performed to measure natural vibration frequency and mode shape. The results of these two field measurements were compared and verified by the 3-dimensional structural analysis results. From the axial force measurement and structural analysis, the roof load was estimated 4.763kN/m2, and this figure belongs to the general range of the traditional timber building. The roof loading pattern of 32 regions was applied to the analysis model, it showed 98.36% accuracy for the measured column axial forces. From the comparison between ambient vibration measurement and eigenvalue analysis, the relative rotational stiffness of the main structural members were evaluated to be 10~20%. It turned out that the stiffness of walls should be considered in analyzing the traditional timber structure.
