Description

This is the study on fire damages caused by the fire at the factory of Yokohama Bridge Stone Tire Company on the 20th January in 1961; thermal stress of which is, at the same time, calculated. The factory of reinforced concrete is five stories high and its plane is 31M 50cm × 151M 08cm. The fire broke out on the fifth floor. The Foam Rubber storing there had been burning for more than five hours. The heating (Time-Temperature-curve) for the constructing member is considered almost standard one in Japan, corresponding to the second class heating of J. I. S. A. 1302. The thermal stress is 30 T. M. at the columns of the both sides of total span. It is 18 T. M. at the beams of the frame. The said matters, in all cases, are much more over than the calculated stress of member by usual method. As the results of our investigating afterfire, it was discovered that there happened many large cracks or exfoliations of concrete in beams and columns. Many places of slabs and beams were impossible to use again because of fire damages, and had to start over again to manufacture.
