WebMar 26, 2024 · When different seismic force resisting systems are used in the two orthogonal directions of a building and when there is no interaction (shared structural components) between these systems, Section 12.2.2 specifies that the system limitations set forth in Table 12.2-1 apply independently to the two orthogonal directions.
WebIn many buildings, the lateral force resisting system is either a steel or reinforced concrete frame, and aluminum and glass are used for the building envelope to transmit the wind pressure on the face of the building to the steel or concrete frame. When the earthquake hits, the aluminum is just along for the ride.
