The Design And Analysis Of One Flying Swallow Profiled Conceret-filled Steel Tube Arch Bridge

As the most critical role in the bridge family, the arch bridge has been occupying theindispensable position all the time. The flying swallow profiled concrete-filled steel tubearch bridge is one of the competitive power bridges in the urban bridges, by its solelyappealing design, easy construction and long-span superiority. The paper, with anengineering background of the Yitong River flying swallow profiled concrete-filled steeltube arch bridge in Changchun City designing, discusses the new-style arch bridge designwhich appears both graceful in figure and historic in culture trait, is designed by filteringbridge type scheme, drawing bridge structure, analyzing bridge static force and aseismaticdesign of bridge. The groundwork that this thesis finishes is:(1) Aimed at location characteristic and construction condition of the Yitong Riverbridge project, discussion selecting scheme, confirm as the flying swallow profiledconcrete-filled steel tube arch bridge design of prestressing force finally.（2）By programs comparing and size of the program drawning up by the forcecharacteristics of the structure, a reasonable choice of structure size, to meet the structuralsafety of the premise, to make the bridge more economical, reasonable and beautiful.（3）This thesis calculate software Midas with finite element, to design stress, bearingcapacity and out of shape to is it is it calculate to analyse to go on of bridge this, it isanalysed that the result of calculation meets the design specification request.（4）This thesis calculate software Midas with finite element, analyzes the main bridgein the50-year10%probability (E1) and2%probability of50years (E2) earthquakeresponse spectrum response, gives the following key parts of the bridge structure inresponse to the results of the seismic response spectrum.
