SURVEY AND RESEARCH ON FIREWALLS BEFORE THE ENACTMENT OF THE BUILDING STANDARD LAW IN 1950 (PART 2): FIREWALLS IN THE WOODEN BUILDINGS OF THE SECOND FACULTY OF ENGINEERING OF TOKYO IMPERIAL UNIVERSITY

In 1942, the Second Faculty of Engineering of Tokyo Imperial University was instituted. Its 2 story timber-framed buildings had reinforced concrete firewalls, simplified firewalls supported from both sides, boundary walls, roof-space bulkheads, and hanging partitions. Although there were fire disasters, it was proved that these walls, especially RC firewalls, were durable and prevented the spread of fire. Compared their structure and frequency of installation of these firewalls to the regulations of laws and acts from 1919 to 1950, it was possible that these firewalls affected the provisions of the 1950 Building Standard Law.
