Bridge & Structure Design
Explore how engineers design strong, stable structures using principles of physics and material science. These projects help students investigate load distribution, truss patterns, material strength, and real-world engineering challenges through hands-on model building and testing.
Truss Bridge Design
- Build and compare Pratt, Warren, and Howe truss bridges
- Test how truss patterns affect load capacity
- Analyze tension and compression forces in each design
Material Strength Testing
- Compare strength of wood, cardboard, popsicle sticks, and straws
- Test how humidity or temperature affects material performance
- Measure bending, breaking, and compression limits
Load Distribution
- Study how weight spreads across beams and supports
- Test single‑point vs distributed loads
- Investigate how support placement affects stability
Earthquake‑Resistant Structures
- Build a model building and test it on a shake table
- Compare cross‑bracing, base isolation, and damping systems
- Study how height and shape affect earthquake performance
Bridge Deck & Roadway Design
- Test different deck materials for strength and flexibility
- Study how deck thickness affects load capacity
- Compare solid vs open‑grid deck designs
Arch & Suspension Structures
- Build arch bridges and test how shape affects strength
- Create a simple suspension bridge using string or wire
- Compare load distribution in arch vs suspension designs
Structural Failure Analysis
- Study how and why structures fail under stress
- Test failure points in beams, joints, and trusses
- Analyze how design changes improve safety
Real‑World Engineering Challenges
- Design a bridge for maximum strength using limited materials
- Build a structure that can withstand wind or vibration
- Investigate how engineers balance cost, safety, and durability
