| Steel-concrete combination beam is a new structure inherited the merit of steel and concrete, which has become the fifth structure as timber structure, bricking-up structure, reinforced concrete structure, steel structure. It is a member in bending using connecting piece to connect steel and concrete. Steel and concrete work together to resist force. When load apply to structure, concrete will be compressed, and steel pulled. Every merit of two materials will be used sufficiently. Experience indicates that it has merit of steel and concrete, and that it is economic in society. Steel -concrete conmination beam will be new deriction of structure, and has widespread use in construction.In this paper, based on a curving steel-concrete combination beam bridge, by using FEM program sap2000 and ANSYS, the auther has studied the mechanics properties of connecting piece, steel-concrete combination beam's mechanics properties influence by different connecting piece ,the calculation method of steel-concrete mechanics properties caused by concrete shrink and creep. This paper relates the calculation method of prestressing force in steel-concrete combination beam, studies the analysis method of design and crack in the negative moment region., analyses dynamic properties of curving steel-concrete combination beam based on a practicable bridge. |
