Bridges planned in coastal areas should be designed specifically to resist the effect of _______
- ADead Load
- BLive Load
- CWind LoadCorrect
- DEarthquake load
Solution
Concept
Coastal areas face strong winds and cyclones, so bridges there need special design for wind load.
Step-by-step solution
1. Coastal areas often have cyclones and high wind speed. 2. Wind pressure on the bridge becomes large. 3. So wind load needs special attention in design. 4. Answer: Wind Load (C).
Explanation
Coastal regions have high wind speeds and cyclones. Bridges there must be designed specially for wind load. Dead load and live load are considered for every bridge, not only coastal ones.
Why the other options are wrong
A: Dead load is common to all bridges. B: Live load is common to all bridges. D: Earthquake load depends on the seismic zone, not on being near the coast.
Shortcut
Coastal means cyclone and wind, so wind load.
Common mistake
Choosing earthquake load because coastal areas sometimes face tsunamis.
Correct answer: C) Wind Load
