1.0 Earthquake Load Combinations: Strength Design
This example demonstrates the application of the strength design load combinations that involve the
seismic load E given in NSCP 2015 ion 208.5.1.1. This will be done for the moment resisting frame
shown below:
Find the following:
Zone 4 C₂ = 0.44
/= 1.0
p=1.1 f₁=0.5
Beam Moment at A
Column C-D axial load
Column Moment at C
Dead Load D
Beam A-B and Column C-D are elements of the special moment-resisting frame. Structural analysis has
provided the following individual beam moments at A, and the column axial loads and moments at C due
to dead load, office building live load, and lateral seismic forces.
