Our present paper deals with the experimental study on the Simplified Fireproof Partition Wall. 1. We designed that the Simplified Fireproof Partition Wall were composed of the steel frams and the special light steel plates and pearlite mortar. 2. We experimented with many tests as follow, that strength test, stiffness test, heating test, and impacting test, about the Simplifieded Fireproof Partition Wall Panels. The Results were summarized as follow. 1. The strength and stiffness of the Special Panels were sufficient. 2. We considered that composing of the Special Panels were easy, and its industrialzation plan seems possible. 3. We obtained enough adaptation of each state displacement, and application about the construction of Multi-Storied Building is possible. 4. We obtained the result that panels were firm aganist 2 hou's heating test. 5. About impacting test, we can not recognized any damage aganist moderate impacts.departmental bulletin pape
