Example 51 Statically Determinate Rigid Jointed Frame

A asymmetric portal frame is supported on a roller at A and pinned at support D as shown in Figure 5.3. For the loading indicated:

i) determine the support reactions and ii) sketch the axial load, shear force and bending moment

Figure 5.3

Solution:

Apply the three equations of static equilibrium to the force system

Rigid Jointed Frame

+Vir tLFV - 0 VA - 12.0 - ( 16,0 X 5,0) - 12.0 + V¡>- 0

Equation
