Direct Strength Method for the Flexural Design of Through-Fastened Metal Building Roof and Wall Systems under Wind Uplift or Suction
… The objective of this thesis is to introduce a Direct Strength Method (DSM) prediction approach for simple span purlins and girts with one flange through-fastened under uplift or suction loading. This prediction method is also applicable for the case when rigid board insulation is placed between …

Cold-Formed Steel Behavior: Elastic Buckling Simplified Methods for Structural Members with Edge-Stiffened Holes and Purlin Distortional Buckling Strength Under Gravity Loading
Elastic Buckling Simplified Methods for Structural Members with Edge-Stiffened Holes: Presently, the current design methods available to engineers to predict the strength of cold-formed steel members with edge-stiffened holes remains largely unaddressed in the North American Specification for the …

Structural and thermal performance of cold-formed steel studs with slits
… bridging, yet these openings can reduce axial strength. This thesis integrates structural and thermal assessments through validated non-linear elasto-plastic finite element analysis (FEA) and complementary heat-transfer modelling. Shell-element FEA models were developed and validated against …

Strengthening of cold-formed steel channels using different reinforcing options and innovative connections
… conduits and water supply systems. The new Direct Strength Method (DSM) was developed to accurately predict their web crippling strength. In addition, this research explored key advancements in CFS systems, including built-up box sections and trusses equipped with advanced Howick Rivet …

Resistance Factor for Cold-Formed Steel Compression Members
This research investigates if the LRFD strength reduction factor for cold-formed steel compression members can be increased above its current value of Ï c = 0.85, which was established by the LRFD Cold-Formed Steel Design Manual (1991) on the basis of 264 column tests. The resistance factor in the …

Experiments on Cold-Formed Steel Beams with Holes
… in the tests to identify trends in ultimate strength. Ultimate strength was observed to decrease with increasing hole depth for 800S200-33, 1200S162-97 cross-sections. Due to small number of specimen and unidentified behavior of the beams, a more in depth study of the behavior of 800S200-43 …

On the strength and DSM design of end-bolted cold-formed steel columns buckling in distortional modes
… investigation on the behavior and ultimate strength of end-bolted cold-formed steel lipped channel columns selected to fail in distortional modes. Besides describing the test set-up and procedure, the available results are presented and discussed: they concern three tests and consist of (i) …
