Experiment 1: Tension Test

• Principle: Tension occurs when a structural member is pulled from both sides.
• Objective: To understand tension, loading, and how the elongation is related to the cross-sectional area and original length.
• Background: Hooke's Law relates stress to strain for elastic materials.
• Apparatus: Test specimens of rubber, test weights, rulers, support stand, and clamps.

Experiment 2: Compression Test

• Principle: When a column is compressed, its length decreases.
• Objective: To demonstrate compression failures in structural members.
• Background: Members can fail by crushing or buckling.
• Apparatus: Plastic rulers, platform scales, sponge, and test weights.

Experiment 3: Bending of Beam

• Principle: Beams loaded transversely bend.
• Objective: To demonstrate bending behavior in beams.
• Background: The moment of inertia affects deflection.
• Apparatus: Beams, metal and wood bars, test weights, ruler, and stand.

Experiment 4: Fatigue Failure

• Principle: Repeated loading can weaken materials causing fatigue failure.
• Objective: To analyze fatigue phenomenon.
• Apparatus: Twenty paper clips.

Concepts of Structural Safety and Equilibrium

• Structures need to be strong enough to handle applied loads.
• Loads include weight, cars, furniture, wind, and water pressure.
• Stress in a member is its load divided by the cross-sectional area.
• A safety factor is used to avoid failure by ensuring stresses don't exceed allowable stress limits.

Equilibrium of Bodies

• Equilibrium occurs when the forces cancel out.
• Forces affect a body's position and rotation.
• Moment of force describes a body's tendency to rotate.

Analysis of Trusses using SAP2000

• The joint equilibrium method analyzes forces at each joint using basic physics.
• Illustrates the use of SAP2000 (structural analysis software) for such analysis.

Design of a Truss Bridge using SAP2000

• This module outlines considerations for analyzing a Warren truss bridge using SAP2000.
• Assumptions made regarding vehicle loads and bridge dimensions are included Analysis involves finding the internal forces in each member of the bridge.
