Abstract


Stiffening girder suspension bridge is often used to structure type : steel truss beams and flat streamlined closed -section box girder . Due to the terrain conditions , the mountain large multi- span suspension bridge construction truss stiffening girders . Shanghai-Chengdu Expressway Siduhe King suspension bridge stiffening girder truss loader with temporary segments connected to the relations between research and come to some conclusion for reference . This paper first introduces a steel truss suspension bridge deck system structure type Siduhe of suspension bridge deck system construction technology . The analysis shows that the truss stiffening girder two loading modes : fully connected , connect the full planking \Clarify the impact of a steel truss girder ultimate state of internal force distribution in different loading methods on the state of the internal force distribution . Articles using then the MIDAS / civil calculated finite element model of the analysis software SIDU RIVER BRIDGE create space , in order to bridge the state is the initial state , the use of REVERSE ANALYSIS connection \the planking \Finally, we discuss the relationship between the truss stiffening girder segment temporary connection bridge deck loading mode . Were calculated comparing several different segments connected in the bridge deck loading process of stiffening girder stress , to determine the optimal temporary connection with certain guiding significance truss stiffening girder deck construction .
