With the other conditions of Example 2 unchanged, the force law of the arch is analyzed with joint different rigidity ratios μ, as shown in Fig. 4.11.
Fig. 4.11Curves of internal force along with the change of μ in different cross-sectional positions
Figure 4.11 shows:(1)The equivalent joint rigidity ratio μ has an influence on the internal force distribution of each cross-section. The influence is more significant on the bending moment.
(2)The variation of the equivalent joint rigidity ratio within the same magnitude will not fundamentally change the internal force of the arch cross-section.
