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.

Course Structure

Classroom Lectures, homework middle and finale exams.

If blended teaching should be required, all the necessary measures will be introduced


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.
