The article originates FengSLab, author Liu crossover. 1. The article combined main content to bend newly help crowded technology, put forward to bend pull crowded arched girder, it is certain to gifted to play component part of crowded profile bridge beforehand arch is spent, stand certainly in order to offset to deflection. In the meantime, the article is crowded to pulling profile is sectional undertook optimizing, because of,avoided successfully inflectional the component part that cause is premature invalidation. The article puts forward curve the design method that helps crowded arched girder still can use traditional and flat component part directly to undertake designing, the advantage is clear. Everybody is good, I am answer material draws crowded profile, be by the answer material goods that enhances fiber material and base material course to haul crowded craft serial production. Predestined relationship of ala of A) press press board and side direction of substance of Liang Zheng of local and inflectional B) turns round celiac board inflectional C) is local with whole inflectional mutual influence bends pull crowded, “ presses straighter more”The tradition draws the question with big deflection of existence of crowded flat bridge, meeting “ presses curvedder ” more. But if shift to an earlier date to have bridge wriggle through the earth, OK “ presses straighter ” more. Pull crowded arched girder through bending, it is certain to gift to play component part of crowded profile bridge beforehand arch is spent, can offset significantly perpendicular to deflection. Curve those who pull crowded arched girder beforehand arch is spent is to pass the “ in manufacturing technology to curve ” to come true. Pure the profile that draws ” and “ to squeeze ” to produce by “ is flat, and bend in helping the process that squeeze even if helps ” in “ , undertake “ bends ” at the same time (see a picture 4) , the profile that such production come out has curvature with respect to can natural belt. New-style bend pull crowded arched girder to study the article combined to bend newly help crowded technology, sectional to labour word bridge undertook preventing inflectional optimize, put forward new-style bend pull crowded arched girder (see a picture 5) , this bridge passes bolt joining together by 3 identical labour word bridge and become. Curve the mechanical performance that helps crowded arched girder to understand, the article had 3 groups of bend test, include a group of 7 meters long arched girder (see a picture 6) , with two groups of 12 meters long arched girder (see a picture 7) . Consider to discover through the experiment, 3 groups of arched girder (SS-7, SS-12A and SS-12B) the mechanical show that all has line flexibility (see a picture 8) . The in crossing displacement of 3 groups of arched girder is respectively 69, 235 with 199 millimeter, all be less than its beforehand arch is spent 109, 322 with 322 millimeter, certifiable curve those who pull crowded craft to gift beforehand arch is spent can offset pull the vertical stroke with crowded bigger profile to deflection. In the meantime, 3 groups of arched girder all can achieve its data strength and destroy eventually, incorporate is on alar predestined relationship board press press is statified destroy. For the destruction of arched girder of test and verify mode destroys and rather than for data strength inflectional destroy, to the ala predestined relationship board is mixed the data of meet an emergency of celiac board undertook an analysis. With the ala predestined relationship board should turn into exemple (see a picture 9) , of 3 groups of arched girder go up alar predestined relationship board the load that all showed line flexibility - curve of meet an emergency, this curve is certifiable predestined relationship of arched girder ala board did not produce local and inflectional phenomenon (extreme of SS-7 yellow curve because material is statified destroy and appear inflection point, be not inflectional bring about) . The article still used method of existing and inflectional design to undertake academic test and verify to the inflectional intensity of arched girder, what analysed 5 kinds to differ in all is inflectional destroy mode (see a picture 10) , include celiac board to press bend, celiac board issues press press in concentrated force action inflectional, abdomen board is in curve action to fall local and inflectional, outside flank predestined relationship board local and inflectional with inside ala predestined relationship board is local and inflectional. Theoretical analysis discovers 5 kinds of inflectional collapse strength all are more than test result, and test result is more than an ala press press of predestined relationship board is statified collapse strength, in view of this, the arched girder that the article puts forward can be avoided be affected at inflectional problem and achieve its data strength. 5. The article passes design method finite yuan of imitate dug those who curve the mechanical function when pulling crowded arched girder and tradition to pull crowded flat Liang Zaijian to raise is different (see a picture 11) . Pass finite yuan of analysis is OK discovery, use existing curvature (rice of = 56 of radius of bend) brief the mechanical performance that raises arched girder and flat component part are basic and same. In view of this, bend in the design when pulling crowded arched girder, the design method that can use traditional and flat component part directly undertakes designing, great rate land was reduced use curve the technical difficulty that plays crowded arched girder. Project application and future look into near future, use article puts forward bend pull crowded arched girder, already built a 20 meters long corridor bridge (see a picture 12) , this bridge is located in the smelt metal in Beijing to build grind courtyard. This corridor bridge all satisfies design requirement in the respect such as intensity, deflection and vibration, below the requirement that raises in the solid that carry a department especially, the meeting inside bridge produces certain axial power, make this bridge has the pattern getting power of shallow arch, increased structural stiffness further. Use bend pull crowded arched girder, can improve the mechanical performance that helps crowded profile further, extend composite material to be in greatly the applied limits of civil engineering domain.

Squeeze to strengthen domestic and international composite material to pull shape the technical communication of craft and market butt joint, advance forward position craft, advanced equipment and applied product development, drive catenary of composite material entire industry to optimize upgrade, study pulls crowded new technology, understanding to draw crowded new facility, master terminal new application, understand thoroughly market new trend, international of scan widely of answer ability network, home of base oneself upon, is on October 2021 27-29 day in Zhejiang? Jia Xingshao opens “2021 international composite material to pull crowded craft to apply height forum and plant site to demonstrate to groom meeting ” . This second conference pulls crowded craft and applied ” to give priority to a problem with “ composite material, kelaosimafei assist do. The conference plans to invite international to play crowded technology expert, help research and development of crowded products company the splendid report that total industry and scholar of expert of terminal application domain make technology and applied photograph union, craft and market phase tie.
