The purpose of the present invention is to manufacture and construct a steel arch bridge in which high construction cost due to the large amount of steel materials is necessary economically. The present invention provides the tide steel arch bridge structure capable of being reasonably and economic manufactured in structural terms by applying compression tensile strength to a steel-reinforced tension member of the tide steel arch bridge in which arch ribs and steel girders are connected to reduce a sectional force generated in the steel girders, improving the economic efficiency of the steel arch bridge by replacing a steel horizontal beam installed between the steel girders to support a bottom plate of a normal steel arch bridge and to deliver a load of the bottom plate and an active load to the steel girders into a precast (PSC) beam for a horizontal beam to reduce the whole weight of the steel arch bridge, and obtaining excellent structural stability by reducing weak elements of the steel structure which may cause fatigue failure and the like and a construction method of the tide steel arch bridge structure. |
