- •
The torsional response of symmetric buildings due to wave passage in the near-fault region is investigated.
- •
The resonance response occurs when the pulse period is close to the torsional period of the building.
- •
Wave passage effects are controlled by the wave apparent velocity, rather than the local site conditions.
- •
Simplified pulse models can represent broadband near-fault motions for large torsional response.
- •
The maximum relative twist at resonance is found to be ~10−3 rad.
