Title

STUDY OF SEISMIC BEHAVIOR OF COLD-FORMED STEEL FRAMES SHEATHED BY FIBER CEMENT BOARDS

Pages

  81-90

Abstract

 In recent times, the use of cold formed steel (CFS) structures in housing industry has increased worldwide due to its great advantages, such as their light weight and high speed construction. In addition, the possibility of mass production and industrialization, quality control of construction and performance are other advantages of this type of structures. Although CFS walls are not new and have been used as non-structural components for many years, their application as the main load-bearing structural frames is relatively new, and as a result, appropriate guidelines that address the seismic design of CFS structures have not yet been fully developed. In addition, the lateral design of these systems is not adequately detailed in the available standards of practice. One of the currently-in-use lateral resistant systems for light steel buildings is steel SHEAR WALLs sheathed by FIBER CEMENT BOARDs (FCB). FIBER CEMENT BOARD sheathed panel lateral resistant system is already being used in housing industry though there are very few studies on the structural performance of these systems. In this paper, the SEISMIC BEHAVIOR of shear cold formed steel walls sheathed by fiber-cement board panels is investigated. For this purpose, finite element nonlinear analysis is employed using ANSYS software. The impact of some structural characteristics on the behavior of frames, including geometric imperfections and residual stresses are also studied. In addition, the ratios of height to width, studs thickness, FIBER CEMENT BOARDs thickness, and studs spacing are investigated. Of particular interest are the specimens' maximum lateral load capacity and deformation behavior as well as a rational estimation of the seismic RESPONSE MODIFICATION FACTOR. The study also looks at the failure modes of the system and investigates the main factors contributing to the ductile response of the CFS walls. A discussion on the calculated response factors in comparison to those prescribed in the relevant codes of practice is also presented.
