- Curved bottom chord
曲線形下弦桿 - The research information of the slab that has been used for forepassed decades is extremely few . there is a lack of the method of calculating load bearing capacity of slab with slightly curved bottom in our bridge criterion
在過去的幾十年中，微彎板的研究資料極少，我國橋梁規(guī)范中尚無微彎板的承載力的確定方法。 - Because it is simple to make manufacture slab with slightly curved bottom , and is economical to use steel , and is relatively great in aspect of load bearing potential capacity , the slab often has been used as braced arch and rigid - frame arch bridges " deck slab in 1970s and 1980s
由于微彎板具有制作簡單、用鋼量省、承載潛力較大的優(yōu)點，因而上世紀七、八十年代，在剛架拱橋、桁架拱橋中常用作橋面板。 - On the basis of the test and finite element analysis , and on the experience of exsting research payoffs , this paper advance the method of calculating load bearing capacity of slab with slightly curved bottom considering membrane effect of the slab , and deduce the corresponding formulas
在試驗和有限元分析的基礎(chǔ)上，借鑒已有的研究成果，本文提出了考慮薄膜效應(yīng)時確定微彎板承載力的方法，并推導(dǎo)出相應(yīng)承載力計算公式。 - The mass of the slab have diseases in varying degrees by investigation , so the problem faced us is to strengthen and remake the slab . in addition , the slab will be used in underdeveloped region of our country . therefore , it is very important to evaluate the load bearing capacity of slab with slightly curved bottom
微彎板在橋梁中使用已有三十多年，在調(diào)查中發(fā)現(xiàn)大多微彎板都存有不同程度的病害，也就面臨著對舊橋微彎板的加固改造的問題；另外，在我國某些經(jīng)濟尚不發(fā)達地區(qū)的橋梁建設(shè)中仍在采用，因此，對微彎板的承載力的正確評定也顯得十分重要。
