4 cards from this section. Quick, good the night before a test.
What do response modification factors do?
Think about how buildings are designed to absorb forces.
What is an R-Factor?
This factor is essential in seismic design codes.
What is the primary purpose of response modification factors?
Consider the outcome of their application in structures.
True or False: R-factors are uniform for all types of structures.
Think about the differences in types of building systems.
Given a building with an R-factor of 4, calculate the expected seismic forces if the base shear calculated is 120 kN.
Remember to divide the base shear by the R-factor to find the modified force.
Discuss the implications of underestimating the R-factor for a hospital in a seismic zone and suggest retrofitting measures.
Think about how retrofitting can enhance energy absorption in existing buildings.
