Fig. 8 Charts indicating the percentage differences in the results obtained for girder No. 2
Comparing the two graphs, it can be seen that in the articulated system the reduction
of span moments is smaller, and the support moments change not as much as in a
continuous system.
3.2 Girder Number 2
The results obtained for girder number 2, presented in Fig. 8, show a clear increase
in the value of support moments for a bridge without hinges and a decrease in span
moments. In the case of constructions with hinges in the middle span, the moment
values increased slightly.
3.3 Girder Number 3
Analyzing the results obtained for girder number 3 (Fig. 9), there is a significant
increase in the span moment in the middle span, both in constructions with and
without joints. The support moments M2 and M4 also increased (smaller increase in
the articulated bridge). Spanning moments M1 and M5 slightly increased in the object
with joints, and their value dropped in the second structure under consideration.
