1. Load Combinations
Example(1):
Find the maximum vertical reactions for the frame
supporting the shown loads
Using ASD Method & LRFD Method for load
combination
Dead Load including self-weight of structure (DL=5
KN/m’)
Live Load of occupancy (LL=5 KN/m’)
Wind Load (W=5 KN/m’)
Earthquake (E=20 KN)
Combinations Solution
L=5m
H=5m
E=20kN
DL=5kN/m’
LL=5kN/m’
W=5kN/m’
