Respuesta :
It can be built with more structural benefits such as blast resistance, earthquake resistance, more durability, Other benefits include economical construction and less construction duration
One of the important factor that would have made this particular bridge design non redundant is that the design engineers might have calculated the wrong load factors for design. So this might have made the bridge non redundant. Based on the partial diagram, it is understood that the end supports were moved inside at the time of failure. Moving the supports inside might have made the structure cantilever while might have caused the tensile failure and the failure of the truss. Duplessis bridge collapsed in 1951 due to adverse temperature. Design Engineers have not accounted this adverse temperature conditions while designing due to lack of blast resistance, earthquake resistance, more durability. Reichsbrucke bridge collapse in1976.This is due to the improper/inadequate design of reinforcements of the columns. Precast construction of concrete structures is one of the special method which allowed it to be constructed and moved in to position
