Structural Design for Non-Structural Engineers - EIT

To derive the horizontal reaction at node 1, equate the horizontal components of the external forces with the R 1 h, R1H = 20cos 45º + 10cos 45º = 21.2132 kN. Now, to determine the forces in the members, we will consider the horizontal and vertical equilibrium of joints separately. For Joint 6, Σ Fx = 0, F65(sin 45º) = 7.071, F65 = 10 kN (C)
