Reliability Assessment under Combinations of Snow Load Effect: The Lightweight Steel Structures with Gabled Frames and Components Designs

Abstract:

Purpose: to assess reliability factor of Gable Framed Lightweight Steel Structural and Components, under combination of load effect of permanent loads and snow loads. Method: JC method is adopted in the calculations. From reliability of geometrical meaning, transform the solving of reliability problem into the finding of minimum constraints, and calculate reliability indicators by using a non-linear programming called ‘Lingo’ software. Results: based on dead load plus snow load, and combination of dead load plus snow load and wind load, to calculate reliability indicator of structural components under axial tension, axial compression, and eccentric compression. Conclusion: when combined with snow load, reliability indicator (of Gable Framed Lightweight Steel Structures and Components) is less than the standard permitted reliability indicator, which is beta=3.2.
