Corrugated Steel-Reinforced Concrete Combination Bridge Panel Capacity Experiment

Along with our country's economy fast development,the requistion of highway bridge is higher and higher.bridge deck,as the crucial component of bridge,directly affects safety running of bridge. While the existing some bridges in overload appeared under the influence of the main structure in good condition, and bridge panel in orer vertical shear failure in the situation, in using current measures for strengthening, bridge panel will still appear damage, in order to solve the problem, this paper proposes a new kind of bridge structure form, corrugated steel—reinforced concrete bridge deck .This article have conducted a preliminary study on composite corrugated steel—reinforced concrete bridge deck through the form of investigativetest. The article studies the intructure of the new brigde deck and load capability between tow points loaded regarded it as one-way slab in the state of simpley supported beam,especially shear. Based on analyzing the instructure Strain and stress,overall fracture morphology and load capability,it makes clearly that the composite bridge deck solves vertical shear problem, upgrades furtherly the bridge deck's load capability and stiffness and resists influence of the existing overload.else, the composite corrugated steel—reinforced concrete bridge deck has a little slippage beteen structiral concrete and steel plate and whole performancei well as composite structure.Based on experimental study,the article calculate deflection and load capability of composite corrugated steel—reinforced concrete bridge deck, taking example by method of calculation about deflection and load capability of reinforced concrete. The numerical simulation results are so in good agreement with those obtained from experiments that they can provide reference data for actual engineering.at last ,we apply Practical calculation methods to actual engineering.and provide reference data for actual engineering...
