Challenge Problems
Push your limits with advanced challenges
Consider two buildings: Building A is in Zone II with a seismic weight of 400 kN and A=0.2, while Building B is in Zone IV with a seismic weight of 600 kN and A=0.3. Calculate their base shears and discuss which building is under more lateral force and why.
💡 Hint: Apply the formula correctly for both buildings and compare results.
If a hospital has a seismic weight of 1000 kN and is located in a very high seismic zone (zone V) where A is estimated to be 0.36, calculate the base shear and discuss its implications for the design.
💡 Hint: Remember to consider the implications for safety and the need for appropriate design measures.
