Seismic force resisting systems examples
WebA passive seismic control system is a shock mitigation method that uses passive techniques. These do not require additional energy sources to serve the mitigation purpose. Instead, it uses the earthquake input motion to activate seismic control. The major examples of passive seismic control systems are: Energy Dissipation Devices http://www.nehrp.gov/pdf/H-18-8.pdf

Webthan Γ0 result in static instability, whereas systems for which Γ is greater than Γ0 are stable under static conditions. 2.2 Seismic conditions The forces acting in the soil-wall system under seismic loading are shown in Fig. 1. Under seismic conditions the resisting and the driving forces are given by the following relationships: WebLateral wind loads are transferred to the wind force resisting system through roof and floor diaphragms. The diaphragm essentially acts as a deep beam spanning between vertical lateral framing members or bracing bays. It drags parallel wind pressure from the roof and walls into the lateral force resisting system (Figure 8).
