What is the purpose of calculating the center of rigidity for a given floor diaphragm?
What is the purpose of calculating the center of rigidity for a given floor diaphragm?
- To analyze the building's resistance to torsional forces (correct)
- To check for irregularity in the building's design
- To determine the building's overall stiffness
- To find the location of the building's center of mass
What is the formula used to calculate the center of rigidity (X,Y) from the three load cases?
What is the formula used to calculate the center of rigidity (X,Y) from the three load cases?
- X = Rzx / Rzy and Y = Rzz / Rzx
- X = -Rzy / Rzz and Y = Rzx / Rzz (correct)
- X = Rzy / Rzz and Y = -Rzx / Rzz
- X = Rzz / Rzy and Y = Rzx / Rzz
