Discuss:
1. Experimental vs. theoretical values for the horizontal
reactions.
2. A UDL is the most significant contribution to the horizontal
reaction. This is mainly
because of the weight of the road deck of a bridge.
3. What is the relationship between the rise (r) and the horizontal
reaction?
4. Discuss: a three-pinned arch is ideal for sites where the
abutments are likely to
settle. Obviously, the shape of the arch has no bearing on the
horizontal reaction
(given the same span and rise)
