Our team needs to clarify about if we can use horizontal outer bracings at the middle of the Doubled floors and if we will put all the response spectra of the 11 GM compared to the target spectrum for Gm2 in one figure or in a separate figures?
Horizontal bracing cutting through the middle of any floor. For the spectra comparison, showing all the ground-motion spectra along with the target spectrum in one figure is acceptable and fairly common in practice.
