Abstract

This paper examines the seismic performance of Japanese traditional wooden structures considering stiffness and strength aging changes in old structural members. In strength and embedding testing done to evaluate the strength properties of old structural members, results showed that zelkova has a Young’s modulus similar or larger than new members. In nonlinear earthquake response analysis for a Kiyomizudera model based on test results, maximum angle response of columns was decreased reflecting old zelkova stiffness and strength.
