Learning Objectives

To show the structural response and the preliminary design of structures and structural components of architectural systems under stati forces.

  • Analyze and design structural members subjected to tension, compression, torsion, bending and combined stresses using the fundamental concepts of stress, strain and elastic behavior of materials.
  • Utilize appropriate materials in design considering engineering properties, sustainability, cost and weight.
  • Perform engineering work in accordance with ethical and economic constraints related to the design of structures.

Detailed Course Content

Introduction-Concept of Stress: Equilibrium of deformable body, average normal and shear stress, bearing stress, allowable stress, factor of safety, deformation-

Stress and Strain - Axial Loading: Normal and shear strain, the tension test, Hooke's law, Poisson's ratio, elastic deformation of axially loaded members, principle of superposition, statically indeterminate axially loaded member,thermal stress.

Pure Bending: Shear and moment diagrams, the flexure formula, eccentric axial loading, un-symmetric bending.

Shearing Stress in Beams and Thin-Walled Members: The shear formula, shear stresses in beams, shear flow in built-up members.

Torsion​: The torsion formulas.

Transformation of Stress and Strain: Mohr's circle, failure criteria, state of stress caused by combined loading

Deflection of Beams:The elastic curve, slope and displacement by integration method, Mohr analogy.
