Study Notes
Mitigation Plans
- Mitigation plans should consider the following lifelines: Water and sewage systems, Electric power systems, Oil and natural gas systems, Communications systems, and Transportation systems
Earthquake Effects on Natural Environment
- Liquefaction: Strong ground motion can cause water-saturated, unconsolidated soil to act like a dense fluid
- Landslides: Earthquakes can trigger landslides
- Faults: Earthquakes can cause faults to rupture
- Tsunamis, flooding, and seiche: Earthquakes can trigger these events
Building Characteristics for Seismic Design
- Period and resonance: Building characteristics that affect seismic design
- Damping: Building characteristic that affects seismic design
- Ductility: Building characteristic that affects seismic design
- Stiffness: Building characteristic that affects seismic design
- Drift: Building characteristic that affects seismic design
- Building configuration: Building characteristic that affects seismic design
How Buildings Resist Earthquake Forces
- Diaphragms: Systems used to resist earthquake forces
- Horizontal bracing systems: Systems used to resist earthquake forces
- Moment-resistant systems: Systems used to resist earthquake forces
Secondary Consequences of Earthquakes
- Fires: Can be caused by ruptured gas lines and damaged fireplaces, flues, and stove pipes
- Hazardous material spills: Can be caused by ruptured pipes and containers
- Utility lifelines: Can be damaged or disrupted, leading to secondary consequences such as water main breaks and loss of power
