Bcn1210 Test 5 Review - Loads I - Ch3

Front 1

List and define the two main classifications of loads.

Back 1

1. Gravity loads: caused by gravitational pull, act vertically
2. Lateral loads: caused by wind and earthquakes, horizontally

Front 2

What are the units of measurement of loads?

Back 2

Kilo-pounds (kips) = 1,000 pounds
1. psf: distributed over a surface (pounds per sq ft)
2. lb/ft, kips/ft: distributed over a linear element (beam)
3. lbs, kips: point load on a column
