| Abstract |
Regression analysis on period-related factors of traditional timber structures was performed based on the site measured period to propose an
appropriate fundamental period formula for such structures. The height of mass, roof area, roof weight, and wall ratio were chosen as
period-related factors. Among 28 available cases, 16 cases were selected as target cases with a relatively high relationship with the
fundamental period. After performing regression analysis on these four factors, the height of mass and roof area were selected as the final
factors which showed a high coefficient of determination and suitability for an approximate formula. An approximate formula for the
fundamental period of traditional timber structures was proposed using the final two factors. The fundamental period derived by the proposed
formula lay between the site measured period and the KDS formula derived period; this showed that the proposed formula secured both
safety and economic feasibility. |
