Cold-formed Steel Design

MCS not only involved with hot-rolled structural steel design but also involved with cold-formed steel design which involves cold-formed thin gauge sections, light gauge profiled steel sheeting and stressed skin design using finite element analysis. This includes generating the geometric properties of the cold-formed element. Among the geometric properties are cross sectional area, shearing area, moment of inertia, radius of gyration, elastic modulus, plastic modulus and etc.

We have assisted roof manufacturers in preparing for their submission to SIRIM for testing and verification for compliance. The calculation provided is based on highest wind load case and strong gust as well as under cyclonic condition to ensure reliability and robustness of the steel sheeting under such circumstances. This submission includes result simulation under serviceability limit based on the following test by American Society of Testing Material test methods namely; 

A) ASTM E2322-03 Standard Test Method for Conducting Transverse and Concentrated Load Tests on Panels used in Floor and Roof Construction which uses two loading configuration for traverse load and point (concentrated) load.
B) ASTM E196-95 Standard Practice for Gravity Load Testing of Floors and Low Slope Roofs which uses gravity load, cable and pulleys.
C) ASTM E1592-01 Standard Test Method for Structural Performance of Sheet Metal Roof and Siding Systems by Uniform Static Air Pressure Difference using air pressure
