The Mechanical Properties of Steel

This lecture addresses the mechanical properties of structural steel. Starting with a discussion of the different shapes and cross sections that are available for engineers, we’ll move on to a discussion of material properties such as yield strength, tensile stress, modulus of the elasticity, and other properties. Finally, we’ll close with a discussion about using the AISC Steel Construction Manual to select the appropriate grades of steel for different steel shapes. 0:05 - Introduction 1:04 - I-Shaped Sections 8:19 - Channels 9:50 - Angles 11:50 - Tee Sections 12:33 - Hollow Structural Sections 16:36 - Flat-Rolled Steel 18:35 - Dimensional Tolerances of Rolled Shapes 21:04 - Cold Formed Steel 26:09 - Mechanical Properties of Steel 49:33 - Material Selection in the AISC Manual 56:29 - Steel Availability ASTM A6: Standard Specification for General Requirements for Rolled Structural Steel Bars, Plates, Shapes, and Sheet Piling ASTM E8: Standard Test Methods for Tension Testing of Metallic Materials ASTM A370: Standard Test Methods and Definitions for Mechanical Testing of Steel Products AISC 360-22: Specification for Structural Steel Buildings Load Type, Load Combinations, Reliability Index, Resistance Factor, Load Factor
