ENGR 100 Lecture Notes - Lecture 20: Chaps, Cantilever Bridge, Systems Engineering
Document Summary
Ralph freeman was simply a designer and focused on detailed calculations. Bradfield was the systems engineer and oversaw the entire project from conception to final validation. Bradfield certified the bridge with a physical demonstration of the bridge loaded with trains. Bradfield rode the train across the bridge to verify its stability. There was a change from a cantilever bridge after the long straight portion on the north side could not accommodate the sharp curve at milsons point station so an arch bridge was adopted. List the test performed and their main purpose. 7660 tons including 96 tons of trains were loaded on the quarter points of the bridge deck to verify its capacity. Increase of number of stay cables to support bridge arches self-weight during construction. Telephonic communication between crane drivers and work crews. Photographer was not approved to document construction because bradfield stated the. Smooth curve before bridge (arch design) cantilever bridge unsuitable.
