The Seismic Infill Wall Isolator Subframe (SIWIS) system is developed for use in building frames with masonry infill walls in order to prevent damage to columns or infill walls and minimize life-safety hazards during potentially damaging earthquakes. The SIWIS system, which consists of two vertical and one horizontal sandwiched light-gauge steel plates with "rigid-brittle" elements in the vertical members, is designed to allow infill wall-frame interaction under wind loading and minor to moderate earthquakes for reduced building drift but to disengage them under damaging events. The SIWIS system acts as a "sacrificial" element just like a "fuse" to save the infill wall and frame from failure. This paper introduces the concept and presents some analytical results for the behavior of a finite element model of an infill wall with SIWIS elements.
