Abstract
The understanding of tensile technology has arguably revolutionized the engineering and construction of long span structures, specifically the design of lightweight bridges. Various materials have been used as tension members carrying most if not all loads in all sorts of bridge-like structures for thousands of years, i.e. rope walkways in Chinese mountains. Later, in mid centuries iron chains have been used to carry much heavier loads of bridges and draw platforms. All sorts of hemp (and other natural fibers) ropes were utilized for smaller temporary structures, in mining and in the sail ship industry, of course. In modern times, one of the pioneers in engineering long span tension structures was Eng. John Roebling. His first wire rope suspension aqueduct was built in Pittsburgh in 1844-1845 and was, arguably the 'game changing' use of new material for long span structures.
