Sample Instructions

The Studica Robotics Earthquake Shake Table is used for data-driven design of safer buildings. Students create their design of a building for earthquake resistance and conduct experiments to test building modifications. Analysis of the data sets are used to develop a final design considering the building height, safety and associated costs.

Please note: The shake table can be used in conjunction with a NI myDAQ (or equivalent) and the former Pitsco myQuake circuit board or other similar instruments. You can also bypass the myDAQ and circuit board with the utilization of a separate DC Motor, Barrel Connectors and a Video Analysis application (not included).

Dimensions: Top plate - 5.75" x 5", Bottom plate - 7.75" x 8", Height - 2.5"

Tip: Using the Earthquake Shake Table to capture video footage and collect oscillation data

Key learning objectives and uses include the following:

Earthquake Engineering Education:
- Hands-On Learning: Educational institutions use earthquake simulation tables to provide students with hands-on experience in understanding the principles of earthquake engineering. This practical exposure helps students grasp complex concepts related to structural dynamics.
- Experimentation: Students can conduct experiments on small-scale models to observe how various factors, such as building materials or structural configurations, impact a structure's response to seismic activity.
Structural Testing and Research:
- Material Response: Engineers use earthquake simulation tables to test how different materials and structures respond to seismic forces. This helps in designing buildings and infrastructure that can withstand earthquakes.
- Structural Dynamics: Researchers study the dynamic behavior of structures under simulated earthquake conditions. This includes analyzing vibrations, deformations, and modes of failure to improve earthquake-resistant designs.
Design Verification:
- Prototyping: Engineers and architects use earthquake simulation tables during the prototyping phase of building design to verify the effectiveness of earthquake-resistant features before construction begins.
- Innovative Solutions: Researchers and designers can experiment with new and innovative solutions to enhance seismic resilience in structures.
Emergency Response Planning:
- Scenario Testing: Emergency response agencies use earthquake simulation tables to simulate various seismic scenarios. This helps them plan and prepare for potential earthquake events, improving their response capabilities.
- Evacuation Planning: Simulated earthquake scenarios allow city planners and emergency responders to evaluate and refine evacuation plans for areas prone to seismic activity.
Equipment Testing:
- Validation of Equipment: Critical equipment, such as medical devices or laboratory instruments, may need to be tested for their ability to function during and after an earthquake. Simulation tables provide a controlled environment for such testing.
- Quality Assurance: Manufacturers of earthquake-resistant equipment use simulation tables to ensure that their products meet safety standards and can withstand seismic forces.

Sample Video Analysis Instructions

Objective:

Capture and analyze the motion of a structure or object during a simulated earthquake using the Studica Robotics earthquake shake table and Vernier Video Analysis software.

Items Required:

A. Studica Robotics Earthquake Shake table [Studica part #: 80002]

B. Adapter pigtail (included with the Earthquake Shake table)

C. Motor Speed Controlle

D. Female barrel connector

E. 12V–1250mA AC/DC power adapter (included with the Earthquake Shake table)

F. Computer or mobile device running with video analysis software (not shown)

G. Camera tripod if using mobile device (not shown – for stable video capture)

H. Sticky notes (not shown – used as visual markers)

Setup Instructions:

1. Assemble the Electrical Components

Connect the 12V–1250mA AC/DC power adapter (E) to the female barrel connector (D).
Plug the female barrel connector (D) into the Motor Speed Controller (C) input port.
Connect the adapter pigtail (B) from the motor on the Studica shaker table to the output terminals of the Motor Speed Controller (C).
Use the PWM dial to control oscillation frequency. Gradually increase frequency to overcome stall.

2. Prepare the Shaker Table

Place the object or model structure onto the Studica Robotics Earthquake Shake table securely.
Affix sticky notes or high-contrast markers to parts of the object to serve as a target for tracking

3. Set Up the Camera

Mount your camera or device on a tripod, aligned perpendicularly to the plane of motion.
Ensure the entire table and the marker(s) are visible and in focus.
Consider using a plain, high-contrast background to aid video analysis.

4. Record the Motion

Turn on the shaker table using the PWM controller.
Record a 5–10 second video capturing the oscillations of the object.
Make sure the camera remains stationary during recording.

Video Analysis Instructions:

Using Vernier Video Analysis:

Open the recorded video in the Vernier Video Analysis
Set the scale using a known length (e.g., sticky note width or a ruler visible in the frame).
Mark a point of interest (e.g., a sticky note on the top of the structure) for
Collect position time data.
Analyze oscillation frequency, amplitude, and damping effects as

Safety Tips:

Do not run the shaker table continuously for more than a few minutes to prevent motor
Ensure all wires are properly connected and
Keep fingers and loose items away from moving parts during
