内容記述 Cold-formed steel-framed gypsum partition walls (hereinafter referred to as partition walls) sustain the seismic damage induced by small story drifts. The impacts on the functional deterioration and monetary loss of buildings are enhanced in earthquake events where structural damages are limited. Although the boundaries of partition walls vary by location in a building structure, the existing studies assume a typical partition wall surrounded by a frame consisting of columns and girders. In particular, the vertical boundary members vary from a column, stud column, and wall panel. Our present work investigates the influence of the boundaries on seismic damage and fragility assessment of partition walls using an experimental dataset of cold-formed steel-framed gypsum partition walls with various boundaries obtained at an E-Defense shake table on a four-story steel frame. A damage mechanism model considering the deformation and rigid body motion of the partition walls and boundaries suitably explains the observed damage variations and underlying mechanisms. This study also presents the non-negligible impact of boundaries on the fragility and expected repair time and cost model of the partition walls. The presented results are critical in providing references for the layout of partition walls, damage predictions, construction improvements, and repair strategy.
