石家庄铁道大学四方学院毕业设计AbstractBridge is an important part of our city,I design is one of the many bridge types-simply supported beam bridge,it is widely used in small span beam bridge,stress and structure is simple,easy to build.This graduation project is about using Midas/civil software to design highway reinforced concrete t-beam bridge.According to the hydrogeological conditions,a reasonablebridge design scheme was selected,and the final scheme was determined to be the design of3 20 highway reinforced concrete t-section simply supported beam bridge based on Midas/civil.Including investigation and research,foreign literature search and translation;Reasonableselection of section size;Midas/cicil software was used to establish the structural section,nodes,elements and supports,calculate the geometric characteristic value of the section,and generate the finite element model of the structure in the form of beam element.Load the main beam according to the code;According to the design specification of highway bridge,load is applied on the bridge under the limit state of normal use and the limit state of bearing capacity.The finite element software is run to check the reaction force,internal force and stress of each node and unit of the bridge structure under various load combinations.Finally,according tothe combined design value of bending moment and the form of bridge section,reasonable reinforcement is carried out.Key words:t-section finite element model main beam design load combination section reinforcement2
