Our present paper deals with the experimental study on the Simplified Fireproof Partition Wall. We designed the Simplified Fireproof Patition Wall Panels and Fireproof Mortal Blocks as large as life size. Wee xperimented with several test as follow,composing test,stiffness test and strength test about the Simplified Fireproof Partition Wall Panels. The results were summarized as follow. 1. We considered that composing of the Special Panels were easy. 2. The conbination of steel frams and special panels well complied with relative displacement of buildings. As the result,we concluded that partition walls were useful component about MultiStories Buildings. 3. The stiffness and strength of the Special Panels were sufficient. 4. We obtained the result that Upper-Joint covered with Fireproof Mortal Blocks were firm against 2 hour's heating test.departmental bulletin pape
