【摘要】：本文針對基于中國橋梁規(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。1.基于已有的中美橋梁規(guī)范對比的研究成果,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;2.基于結(jié)構(gòu)可靠性評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)行基于中美橋梁規(guī)范設(shè)計(jì)結(jié)果的對比分析;3.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ο?確定性對比方面計(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,可靠性主要針對的正截面的抗彎承載能力安全性從可靠性方面進(jìn)行評估,確定性與可靠性方面對比分析了安全系數(shù)與可靠指標(biāo)的關(guān)系。
[Abstract]:Aiming at the difference of prestressed concrete continuous beam bridges based on Chinese bridge code, this paper combines the latest development of bridge structure analysis and structural reliability theory. From the point of view of engineering practice and scientific research innovation, the following aspects have been studied. 1. Based on the existing research results of bridge code comparison between China and the United States, the finite element method is used. The combination of action effect and the magnitude of structural resistance; 2. Based on the inductive analysis of the existing research results of structural reliability assessment, the function function of the structure is constructed by combining qualitative and quantitative methods, and the comparative analysis based on the design results of Chinese and American bridge code is carried out. 3. Taking the prestressed concrete continuous beam bridge as the research object, the deterministic comparison includes the following items: permanent effect and variable action effect. The combination of action effect and flexural bearing capacity of normal section, the reliability is mainly aimed at the safety of flexural bearing capacity of normal section from the aspect of reliability. The relationship between the safety factor and the reliability index is compared and analyzed in terms of certainty and reliability.
