Abstract
Because of the conventional tight-fit construction of masonry infill walls within
structure frames and their large in-plane stiffness, infill walls participate in
resisting wind and seismically induced loads. Although beneficial during wind
loads and minor earthquakes, the lateral load resistance of infill walls during
strong events can damage the wall or the frame. 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 de
