Abstract
As the span of conventional cable stayed bridge crosses 1000 m or longer, a horizontal force component of stay cables causes large amount of axial pressure in girder, which leads an increase of girder dimension and height respectively. Hence it is too difficult to follow the cost economy aspect of the bridge. In 2014, Mr Xudong Shao has invented a new type of cable stayed bridge system with crossing long stay cable, which is considered as the economical as it reduces the axial pressure in the steel girder. In this work, My attempt is to study steel box girder of the new bridge system under load combination of dead load, secondary dead load and moving load as per Indian Standards and to check the effect of reducing horizontal pressure on various structural elements also studied in depth. The given span of the bridge is 1408 m and side span is about 2 x 600 m.
