Different slit configuration in corrugated sheathing of cold-formed steel shear wall

摘要

Recent research showed that shear walls with corrugated steel sheathing demonstrated high strength, high initial stiffness but low ductility under cyclic loading and thus were not favorable for seismic applications. A possible solution by creating openings in the field of the corrugated sheets in order to improve the ductility was newly proposed by the authors. This paper presents an experimental study on the seismic behavior of the cold-formed steel shear walls using corrugated steel sheathings with different slits configurations. A total of 14 full scale shear wall specimens, including seven different slit configurations and one unperforated wall configuration, were tested under lateral cyclic loading. The test results indicate that with proper slit configurations on the sheathing, the corrugated steel sheathed shear wall shows an improved high ductility without significant reduction in shear strength and stiffness. Details of the test program and general results are presented in this paper. (C) 2018 Elsevier Ltd. All rights reserved.
