About 16 experiments were made with model steel-frames of three stories in which one or two girders were heated in constant heating rate by electric furnace. These experiments made it possible to analyze thermal stress within the steel-frames. It can be summarized that large thermal stress appeared in the frame corresponding to binding modulus of the frame. In some cases, the bucklings of heated girders were occurred. When heated girder didn't buckle, yield parts sometimes appeared in the non-heated columns which restrained expansion of it.
