The design and calculation of simply suppprted reinforced concrete T-beam bridge in Dalu Road
Abstract：Bridge is dominated by curved main beam as load-bearing elements of the bridge. Main beam can be solid web beams or joists . Solid web girder structure is simple , manufacture, erection and maintenance than convenient , widely used in small -span bridge, but not enough on the economic use of materials . Girder truss rod axial force , the material can be fully utilized, lighter weight, across a large capacity , and more for the construction of large-span bridges . Static system according to the main beam , pided simply supported beam bridge , continuous beam bridge and a cantilever bridge. Prestressed concrete T- beam bridge has a simple structure , the force clear , material saving , easy erection and installation , etc. across a larger capacity . T-beam bridge built in the country up to the highway . Charpy bridge is the main beam to the hole for the unit ends with a bearing, is statically indeterminate structure . Generally applicable to medium and small span , simple structure , manufacturing, transportation and erection are very easy to use, multi- standard design made to facilitate the production process of industrialization , mechanization of construction components, improve quality and reduce cost. T-beam bridge with T-beam girder bridge as the main load-bearing structure. When the bridge loads generated positive moment , Liang Zuocheng so big and small T-shaped lower edge of the reinforcement will take full advantage of high tensile compressive strength of concrete and steel bridge further than the rectangular material savings , reducing the weight .
The design of reinforced concrete simply supported beam bridge design , the use of ( 30 +30 +30 +30 +30 ) m , with a total span of 150 meters of simple T girder bridge design , full-bridge using prefabricated construction methods , and the use of double-column pier piers , foundation using bored pile foundation . Set in a horseshoe-shaped cross .
