Lateral Seismic Force Solution

STEP 0: Pre-Calculation Summary

Formula Used

Lateral Seismic Force = Vertical Distribution Factor*Lateral Force
F_x = C_ux*V
This formula uses 3 Variables

Variables Used

Lateral Seismic Force - (Measured in Newton) - Lateral Seismic Force is the seismic force that acts in the direction parallel to ground and perpendicular to the direction of gravitational pull of earth.
Vertical Distribution Factor - Vertical Distribution Factor is the ratio of lateral seismic force to lateral force.
Lateral Force - (Measured in Newton) - Lateral Force is live loads that are applied parallel to the ground; that is, they are horizontal forces acting on a structure.

STEP 1: Convert Input(s) to Base Unit

Vertical Distribution Factor: 1.18 --> No Conversion Required
Lateral Force: 8.4 Kilopound-Force --> 37365.0615681401 Newton (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

F_x = C_ux*V --> 1.18*37365.0615681401

Evaluating ... ...

F_x = 44090.7726504053

STEP 3: Convert Result to Output's Unit

44090.7726504053 Newton --> No Conversion Required

FINAL ANSWER

44090.7726504053 ≈ 44090.77 Newton <-- Lateral Seismic Force
