Buckling Analysis, Structural Behavior and Strength of Distortional-Global Interaction in Cold-Formed Steel Lipped Channel Columns
(2020-10-20)Cold-formed steel members are composed of thin-walled sections, forming very slender structural systems easily susceptible to buckling. This unique characteristic obligates designers to deal with the complexity of the ... -
Characterizing Wall-to-Diaphragm Moment-Rotation Response in Cold-Formed Steel Systems via Fastener Limit States
(2020-10-20)Ledger framing is currently the dominant framing system in cold-formed steel buildings and is a popular choice for its flexibility in floor joist spacing with respect to wall stud spacing. In ledger framing, the floor, ... -
Cold-Formed Steel Framed Shear Walls with In-Frame Corrugated Steel Sheathing
(2020-10-20)The objective of this paper is to find an alternative non-combustible high-performance shear wall system that can be used in mid- and high-rise cold-formed steel (CFS) light-framed buildings. To achieve this goal, an ... -
Cold-formed steel properties at elevated temperature: review and proposed equation
(2020-10-20)Cold-formed steel members are increasingly used in the construction industry due to their favorable strength-to-weight ratio and cost efficiency. Knowledge of the elevated temperature behavior of cold-formed steels is ... -
Compression Tests of Fixed Ended CFS Members with Improved Connectors
(2020-10-20)In the compression tests of cold-formed steel (CFS) members, fixed end supports are commonly simulated by fixing the test specimens to end plates by either welding or casting them with high strength adhesives. This is ... -
Cyclic Performance of Steel Sheet Connections for CFS framed Steel Sheet Sheathed Shear Walls
(2020-10-20)The main objective of this research is to study fastener-level force-deformation response appropriate for standard cold-formed steel (CFS) framed steel sheet sheathed shear walls under cyclic loads. Recently completed ... -
The Direct Strength Method for Combined Bending and Web Crippling of Second-Generation Trapezoidal Steel Sheeting
(2020-10-20)Second-generation trapezoidal sheeting, characterised by longitudinal stiffeners in webs and flanges, is loaded near a support by a concentrated force and a bending moment. Currently, design codes predict related failure ... -
Direct strength method for web crippling of lipped channel sections with flanges restrained under ETF and ITF loadings
(2020-10-20)Web crippling is a prominent failure mode of cold-formed thin-walled steel members. In this study, a direct strength method (DSM) is investigated for the web crippling calculation of lipped channel sections with flanges ... -
