Abstract : cable - stayed is used to cable suspension , but cable force is calculated by manual , and only for less than 5 segments , and the prescion is poor . this paper puts forward “ zero moment method ” , which can not only calculate more segmental soupe force , but both temporary joint and fixed joint during construction . the mechanical concept is clear , and it is easy for calculating . it is fit for program , and the illustrations prove that the methods are right 文摘:斜拉扣掛在纜索吊裝中經(jīng)常運(yùn)用,但扣索索力多采用手工計(jì)算,且多用于5段以內(nèi)的吊裝,計(jì)算復(fù)雜,精度低.本文提出“零彎矩法” ,可計(jì)算任意多段扣索索力,既可計(jì)算拱肋在施工過程中各節(jié)段臨時(shí)鉸接,又可計(jì)算各節(jié)段固結(jié)的情況,將兩種連接方式統(tǒng)一成一種計(jì)算方法,力學(xué)概念清楚,計(jì)算簡(jiǎn)便,適宜程,文中最后用示例證實(shí)本方法的正確性
