Study Notes

Reinforced Concrete Design: Course Outline

  • This course covers the design of reinforced concrete structures.
  • It begins with an introduction to reinforced concrete, including its historical timeline.
  • The course will review simple and indeterminate structures.
  • Loads, load computation, and codes are discussed.
  • Design principles for reinforced concrete are covered, including the design and investigation of simply supported reinforced concrete beams.
  • One-way and two-way slabs are explored, along with continuous beams, reinforced concrete columns, and construction techniques.
  • Soil analysis and piling are also included in the course.

Unit 1: Introduction to Reinforced Concrete

  • Fundamentals of Reinforced Concrete: This includes the historical timeline of reinforced concrete.
  • Properties of Concrete and Steel Reinforcement: Understanding the key properties of concrete and steel reinforcement is crucial for the design of reinforced concrete structures.
  • Basic Principles of Reinforced Concrete Design (Stress-Strain Diagram): The stress-strain diagram is a fundamental tool for understanding how concrete and steel behave under load.

Lesson 4: Structures

  • Structure: A structure is an assembly of components that remain in equilibrium and meets criteria for strength, stiffness, economy, durability, and compatibility.
  • Analysis: This involves evaluating stresses, moments, and forces, and plotting them to understand the behavior of a structural component.
  • Design: Determining the dimensions of structural components based on stresses and proportioning is known as design.
  • Simply Supported Structures: These are structures designed to resist loads and are classified by their supports. Examples include beams with hinge or roller supports at both ends.

Lesson 4: Statically Determinate and Indeterminate Structures

  • Statically Determinate Structures: These can be analyzed using basic equilibrium equations.
  • Statically Indeterminate Structures: These cannot be analyzed by basic equilibrium equations alone. Other methods, like strain energy, virtual work, or double integration are required.

Lesson 3: Design of Simply Supported Reinforced Concrete Beams

  • RC Beams: Structural elements designed to carry transverse loads that cause bending, shear, and sometimes torsion.
  • Types of Beams (According to Supports):
    • Simply Supported: Supported at both ends (hinge or roller supports).
    • Continuous: Supported by more than two supports.
    • Cantilever: Fixed at one end and free at the other.
    • Overhanging: A combination of simply supported and cantilever beams.
    • Fixed: Fixed at both ends, preventing vertical movement and rotation.
  • Types of Beams (According to Shape of Cross Section):
    • I-beam
    • T-beam
    • C-beam
