You are tasked with designing a new arch bridge. Given varying live loads expected to act on segments of the arch, propose strategies to maintain structural integrity using deployment of materials and design shapes. What factors must be considered?
💡 Hint: Focus on load distribution variability and impact on design.
A historical arch bridge has a rise of 10 ft and a span of 80 ft. Analyze its stability with a proposed increase in the rise to 15 ft. What are the expected changes in horizontal reaction H?
💡 Hint: Use the formula correctly and compare values before and after the change.
