本文主要研究了钢-混凝土连续组合梁中间支撑处钢筋混凝土桥面的设计技术。(a)建立了考虑局部相互作用的钢-混凝土组合梁的有限元公式。利用Maple软件和MATLAB软件编制了蠕变、收缩应力和变形计算程序,并进行了参数化计算。在此基础上进行了二维有限元分析(MARC),并与部分相互作用组合梁理论计算结果进行了比较。(b)进行了聚合物浸渍混凝土(PIC)钢筋混凝土梁的极限性能和裂缝分析,研究了聚合物浸渍混凝土对梁延性的影响以及在使用极限水平下的裂缝控制设计。此外,还对PIC、现浇混凝土和拉杆组成的系拱型组合板进行了研究,发现系拱型组合板与普通钢筋混凝土板相比是一种有利的结构形式。(c)考虑到降低施工成本的需要,设计2根主梁支撑的连续组合梁是有价值的。本文给出了连续组合梁的设计准则、实际设计中存在的问题以及对比计算的结果。在此基础上,结合欧洲规范对连续组合梁中间支座开裂区混凝土刚度进行了评定。
英文摘要
This study focused on the design technique of reinforced concrete deck at middle supports of continuous steel-concrete composite girders.(a) Finite element for the steel concrete composite girder with partial interaction was formulated. Computer program for stress and deformation by creep and shrinkage was developed by Maple and MATLAB, and then parametrical computation were performed. Furthemore, two dimensional FE analysis(MARC) for creep and shrinkage analysis was carried out, and cpmpared with the results by partial interaction composite girder theory.(b) The ultimate behavior and crack analysis of reinforced concrete beam with polymer impregnatged concrete(PIC) were carried out, and the effect of ductility by PIC and crack control design at service limit level were studied. Furthermore, tied arch type composite slab composed of PIC, cast-in-place concrete and tie bar was investigated, it was found that tied arch type composite slab was favorable structures compared with the normal reinforced concrete slab.(c) For the reason of demand to reduce constructional costs, it is valuable to design the continuous composite girder supported by 2 main girders. In this study, data on table about the design criteria of continuous composite girder, the problems in actual design and the results of comparative calculation were offered. Furthemore, concrete stiffness of cracking zone at intermediate supports of continuous composite girder wes ealuated in considered to Eurocode.
