Making Buildings Better Withstand Earthquakes - Science Nation

The video discusses a successful earthquake test on a six-story wood-framed building using the world's largest shake table in Japan. Led by John Van de Lindt, the project aims to develop safer construction methods for mid-rise wood buildings in earthquake-prone areas. The test simulated a rare, strong earthquake, and the building incorporated innovative designs like an anchor tie down system and performance-based seismic design. Despite logistical challenges, the test confirmed the building's resilience, potentially influencing future building codes.

What was the main goal of testing the six-story wood-framed condominium on the shake table?

• To explore the potential for taller wood-framed buildings in earthquake zones

• To simulate a common earthquake scenario

• To compare wood and steel construction methods

• To test the durability of wood as a building material

What makes the E-defense shake table unique?

• It uses only wooden structures for testing

• It is the smallest shake table in the world

• It can move in three directions simultaneously

• It is located in a densely populated area

What is the purpose of the anchor tie down system in the building's design?

• To enhance the aesthetic appeal of the building

• To provide overturning restraint for the building

• To increase the number of floors in the building

• To reduce the cost of construction

What is the function of the double mid-ply wall in the building?

• To enhance the building's ventilation

• To reduce the weight of the building

• To increase the building's capacity to withstand seismic forces

• To improve the building's insulation

What was the outcome of the simulated 7.5 magnitude earthquake test?

• The building was slightly damaged but remained standing

• The building collapsed completely

• The building suffered significant structural damage

• The building showed no significant structural damage
