Formwork Calculation Panel Strut

This document summarizes the wind load and resulting support reactions on a formwork structure. It calculates: 1) The wind load of 2 kN/m^2 and resulting wind forces of 8.87 kN and 4.80 kN at different heights. 2) The support reactions of R1 = 4.95 kN and R2 = 23.20 kN including lateral and vertical shear components. 3) Checks that the maximum bending moment of 79.92 kNm and shear forces are within the capacity of the formwork members.

R1 = 4.95 kN R2= 23.20 kN


Lateral Shear = Rx1= 4.80 kN Rx2= 8.87 kN TOTAL
Vertical Shear = Ry1= 1.16 kN Ry2= 21.44 kN TOTAL
Max BM = 79.92 kNm

Capacity= 2 x 40 80 kNm
(Provided 2 soldiers)
Hence OK
