Classroom Implementation Plan
Buildings that Resist Earthquakes Better

• Ms. Michelle Daniel Beach, Midpark High School
• Mr. Jaz Dhillon, Withrow University High School
• Dr. Nathalie Mukolobwiez, Saint Ursula Academy

2
The Engineering Design Project

• Students will use the Engineering Design Process
  and their knowledge of Simple Harmonic Motion and
  Earthquakes to retrofit a single story structure
  to resist a low, medium and high frequency
  earthquake

3
Rationale (How it relates to Engineering)

• Earthquakes are a natural phenomena that we can
  not control
• Buildings must be designed or retrofitted to
  combat these destructive forces

4
Background Knowledge

• EnGAGE and Explore

5
Background Knowledge

• Earthquake Dynamics
• Seismic Waves
• Simple Harmonic Motion
• natural frequency, period, resonance, stiffness
• Relationship between buildings and mass-spring
  systems

Objectives

• The Engineering Design Project

20
Students will be able to

• Determine the natural frequency, period, and
  resonant frequency of a structure
• Analyze the effect of an earthquake retrofit
  system (ERS) on stabilization (damping) of a
  structure
• Predict the effects of ERS on the quality and
  quantity of life in the United States
• Utilize the engineering design process to make
  appropriate choices when designing an ERS
• Analyze data to determine the effectiveness of ERS

21
Students will be able to

• Explain how societal issues and considerations
  affect the use of ERS in the United States
• Solve problems involving unit conversions
  (English to Metric)
• Describe the movement of the structure using data
  tables, graphs and sketches
• Derive linear equations that represent the motion
  of a structure
• Represent free vibration and force vibration as
  trigonometric functions and/or exponential
  functions
