Experimental Study on the in-plane behavior of standing seam roof assembly and its use in lateral bracing of rafters
(2020-01)
The standing seam roof (SSR) system is the most commonly used roof system for metal buildings due to its superior durability, water tightness, and energy efficiency. In this type of system, SSR panels attach to Z-shaped ...
Inelastic Lateral-Torsional Buckling Strength Validation for Non-Principal Axis Bending Using Numerical Methods
(2020)
The current design specification for point-symmetric cold-formed steel members in North America (AISI S100) has long applied a conservative simplification for elastic lateral-torsional buckling. This report aims to provide ...
Cold-Formed Steel Gravity Walls with Bridging and/or Sheathing
(2020-01)
The objective of this report is describe experiments conducted on cold-formed steel walls under axial loading with a variety of different bracing conditions. Cold-formed steel wall systems are commonly braced using small ...
Ductility Demands on CFS Structural Connections of Advanced High Strength Steel
(2020-10-20)
The objective of this paper is to investigate the ductility demand for typical cold-formed steel (CFS) connections when advanced high strength steel (AHSS) is used for the components. Although currently AHSS is mostly used ...
Large Deflection Analysis of Beam-Columns with General Sections Using Gaussian Line-element Method
(2020-10-20)
The finite-element analysis method implementing line-elements is extensively adopted for the analysis and design of large-scale structures. The robustness of the element derivations and formulations decidedly impact the ...
Modeling of stress-strain relationship of advanced high-strength cold-formed steel at elevated temperature
(2020-10-20)
Recent material advances in the steel manufacturing processes have led to materials with greatly enhanced capabilities at competitive cost. New grades of cold-formed steels, referred to as Advanced High-Strength Steels ...
Extensions of the constrained Finite Strip Method for thin-walled members: closed sections and sections with rounded corners
(2020-10-20)
The objective of this paper is to provide a derivation for a constrained Finite Strip Method (cFSM) stability solutions that applied to thin-walled members with closed sections and sections with rounded corners. The current ...
Numerical Study of Double Stud LSF Walls Exposed to Fire Conditions
(2020-10-20)
Fire safety of light gauge steel frame (LSF) stud walls is important in the design of buildings. Many experimental and numerical studies have been undertaken to investigate the fire performance of load bearing LSF walls ...
Prediction model of Power-Actuated Fasteners subjected to pull-out from Cold-formed steel plates
(2020-10-20)
An experimental program comprising of sixty-nine cross-tension test specimens was carried out to investigate the pull-out behaviour of Power-Actuated Fastener (PAF) connections joining two cold-formed steel (CFS) plates ...
Fire performance of bio-based PCM lined LSF wall
(2020-10-20)
Light gauge steel framed (LSF) wall systems are made of cold-formed steel studs lined with different types of wallboards. Increased demand for LSF wall systems has led to researchers focusing on improving their fire ...
