Abstract
The main building of Yokufu-en has been designated as a \“Selected Historical
Building of Tokyo Metropolitan Government,” built after the 1923 Great Kanto
Earthquake in the Taisho period. This building was designed by Yoshikazu
Uchida, a famous university professor and his assistant. As a result of the study,
the building has enough strength of structure, and the concrete shows sufficient
compressive strength. However, as the 3rd story has a high eccentric factor it is
necessary to be reinforced for earthquake resistance. The reinforcement plan was
designed for obtaining a prescribed seismic capacity performance in Japan.
Keywords: seismic evaluation, historical-landmark, structural performance
evaluation, Yoshikazu Uchida.
1 Introduction
The main building of Yokufu-en (the main building of current Yokufukai, a
social welfare corporation) reported in this paper was a hospital which was built
to protect people who were affected by the 1923 Great Kanto Earthquake. It was
designed by Yoshikazu Uchida and his assistant Tatuto Toki in 1925 and
completed in 1926 [1]. It is a valuable building designated as a \“Selected
Historical Building of Tokyo Metropolitan Government” in 2001. The building
is currently used as offices. Structural and seismic evaluations were conducted to
check its seismic capacity. This paper reports the details of the technical data
used when the building was designed including the Urban Building Law, and the
