Design of Structures I - CE306

Credits : 3

Prerequisites :CE208

Compulsory/Optional : Compulsory

To develop a sound knowledge on the design of steel structures and design of pre-stressed concrete (PC) structures.
Intended Learning Outcomes
On successful completion of the course, the students should be able to;

  1. Explain the basic behaviour of steel structures.
  2. Design steel members loaded in tension, compression, flexure, shear and combinations.
  3. Design different types of connections in steel structures.
  4. Discuss the attributes of PC structures, construction methods and prestressing techniques.
  5. Design PC beams conforming to a standard code of practice.
Course content/Course description
  1. Design concepts: permissible stress, load factor, limit state
  2. Limit state concept: probabilistic approach, characteristic loads, characteristic strength, and partial factors of safety
  3. Safety, serviceability, durability, fire resistance and other considerations
  4. Physical and mechanical properties of structural steel and their classifications
  5. Behaviour of structural elements, modes of failure, application of codes of practice, standards and specifications
  6. Design of elements in steel structures: ties, struts, beams, columns, design of connections
  7. Robustness of structures
  8. Design of a steel building using a code of practices
