1. Structural Steel Properties In Construction

Structural steel in construction possesses the following common properties: tensile properties, shear properties, hardness, and relaxation.

1.1. Tensile properties

Tensile properties refer to the ability of a material to withstand stretching without deformation. Structural steel exhibits higher tensile properties compared to other materials and is often favored in construction projects. To measure the tensile properties of structural steel, a test sample is typically placed in a tensile testing machine. The machine attempts to stretch the test sample by slowly pulling it until it breaks its grip. Then, the tester records the maximum pulling force the test sample can endure.

The tensile strength of structural steel is determined by measuring and recording the maximum pulling force the test sample can endure.

1.2. Shear properties

At the point of failure under shear stress, the shear strength of a steel structure is specified, and it is approximately 0.57 times the structural steel’s yield stress. The ratio of shear stress to shear strain in the elastic range of a steel structure is the expression for the elastic shear modulus. Typically, the elastic shear modulus of steel structure can be taken as 75.84 GPA or the following formula can be used to calculate the elastic shear modulus.

𝐺 = 𝐸21 + 𝜇

Where:

  • G: Steel structure shear elastic modulus
  • E: Modulus of elasticity of steel structure
  • µ: Position’s ratio

1.3. Hardness

Hardness is a measure of a structural steel’s ability to withstand non-elastic deformation. It also determines several other properties of the steel, such as its resistance to wear, toughness, and formability. There are three different standard tests to assess the hardness of steel: the Rockwell test, the Brinell test, and the Vickers hardness test.

  • The Rockwell hardness test is the most frequently utilized test method since it is easier to perform and more accurate compared to other methods. All metals can use this, with the exception of materials having dents or irregular shapes.
  • The Brinell hardness test is utilized to evaluate materials with a structure that is either too coarse or too rough.
  • The Vickers Test or the microhardness test method is applied for materials with tiny elements, thin parts, or case depth work.

1.4. Relaxation

Relaxation is the phenomenon where the structural steel’s tensile strength gradually changes under the influence of constant stress. This occurs due to the combined effects of stress and exposure to heat. Except in situations with a high risk of experiencing a fire, the relaxation of structural steel is frequently not a critical consideration in the design and construction of steel frame structures.
