【摘要】：本文針對(duì)基于中歐橋梁規(guī)范設(shè)計(jì)的預(yù)應(yīng)力混凝土連續(xù)梁橋的差異性問題,結(jié)合當(dāng)前橋梁結(jié)構(gòu)分析和結(jié)構(gòu)可靠度理論的最新進(jìn)展,從適用于工程實(shí)際和科研創(chuàng)新的角度出發(fā),從以下幾方面進(jìn)行了研究�；谝延械闹袣W橋梁規(guī)范對(duì)比的研究成果,采用有限元計(jì)算作用、作用效應(yīng)組合及結(jié)構(gòu)抗力的大小;基于結(jié)構(gòu)可靠性評(píng)估已有研究成果的歸納分析,采用定性與定量相結(jié)合的方法,構(gòu)建結(jié)構(gòu)的功能函數(shù),并進(jìn)行基于中歐橋梁規(guī)范設(shè)計(jì)結(jié)果的對(duì)比分析;以一次落架施工的預(yù)應(yīng)力混凝土連續(xù)梁橋?yàn)檠芯繉?duì)象,確定性對(duì)比方面計(jì)算內(nèi)容包括以下幾項(xiàng):永久作用效應(yīng)、可變作用效應(yīng)、作用效應(yīng)組合和正截面抗彎承載能力,可靠性主要針對(duì)的正截面的抗彎承載能力安全性從可靠性方面進(jìn)行評(píng)估,確定性與可靠性方面對(duì)比分析了安全系數(shù)與可靠指標(biāo)的關(guān)系。
[Abstract]:Aiming at the problem of prestressed concrete bridge design specification of central difference based on continuous girder bridge, combined with the latest development of the reliability theory of bridge structure analysis and structure, starting from the practical and innovative research perspective, the research from the following aspects. The research achievements of comparative central bridge criterion based on the existing and finite element calculation, the effect of combination and structure force; the analysis of the existing research results of structure reliability assessment based on induction, using both qualitative and quantitative methods, construct function structure, and compares the central bridge design specifications based on the results of a fall; to the prestressed concrete continuous frame construction girder bridge as the research object, the deterministic contrast calculation includes the following items: permanent effect, variable effect, combination of action effects The reliability of flexural capacity of normal section is evaluated from the aspect of reliability, and the relationship between safety factor and reliability index is compared between certainty and reliability.
