The document provides an analysis of load combinations for a structural frame under various loads: dead load (dl), live load (ll), wind load (w), and earthquake load (e). It details the maximum vertical reactions calculated using both the Allowable Stress Design (ASD) and Load and Resistance Factor Design (LRFD) methods, presenting various load combination scenarios. Engineering parameters such as span, height, and load values are specified for accurate calculations.

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’
