STRUCTURAL CHARACTERISTICS AND VIBRATION BEHAVIORS ON THE MAIN HALL OF OHTANIHA HAKODATE BETSUIN (1915)

Abstract

The main hall of Ohtaniha Hakodate Betsuin, which was completed in 1915, is the oldest temple architecture using reinforced concrete structure in Japan. The temple has been designated as an Important Cultural Property of Japan in 2007. In this paper, structural characteristics of the temple based on previous studies were described. Furthermore, evaluation of vibration behavior of the temple by micro-tremor observation and eigenvalue analysis using numerical 3-D frame models were presented. From the results, natural frequencies of the analytical model with decreased concrete Young’s modulus considering aging and construction situation showed a good agreement with the micro-tremor observation results.
