摘要
波纹钢腹板预应力混凝土箱梁桥是一种新型的钢-混凝土组合结构桥梁,它用波纹钢腹板代替传统的混凝土腹板,大大减轻了结构自重。结构受力合理,提高材料的利用率,缩短施工工期,外形美观。与传统混凝土箱梁相比,波纹钢腹板箱梁具有更加明显的经济效益和社会效益。本文结合某波纹钢腹板预应力混凝土箱梁桥,对波纹钢腹板预应力混凝土箱梁桥的设计方法进行研究。
     根据波纹钢腹板预应力混凝土箱梁的轴向受力特性,结合参考文献给出了波纹钢腹板预应力混凝土简支箱梁翼板有效分布宽度的经验计算公式,及体外预应力钢筋极限应力计算方法,根据钢筋混凝土梁的弯曲理论推导出波纹钢腹板预应力混凝土箱梁的极限抗弯承载力计算的基本公式。
     通过分析国内外在抗剪性能方面的研究成果,总结了波纹钢腹板预应力混凝土箱梁剪切屈曲强度的计算方法,给出了波纹钢腹板预应力混凝土箱梁桥设计中波纹钢腹板剪切刚度的计算方法,剪应力强度的计算和验算方法及屈曲稳定的验算方法,提出波纹钢腹板抗剪设计流程。
     以箱梁设计理论为基础,并结合波纹钢腹板箱梁的结构和受力特点,采用乌氏第二理论对波纹钢腹板预应力混凝土箱梁的扭转进行研究。
     剪切变形对波纹钢腹板的挠度影响很大,计算时不可忽略。给出了波纹钢腹板在考虑偏心荷载作用下剪应力的计算公式,同时根据Timoshenko梁理论推导了考虑剪切变形影响的波纹钢腹板箱梁的挠度计算公式。
     波纹钢腹板与混凝土顶底板的连接部是波纹钢腹板预应力混凝土箱梁设计的关键环节,通过统计分析国内外已建和在建波纹钢腹板桥梁的抗剪连接件类型,给出几种常用混凝土顶底板与波纹钢腹板的结合部设计计算和验算方法。
     最后对某波纹钢腹板预应力混凝土箱梁桥进行有限元分析,并用本文提出的波纹钢腹板预应力混凝土箱梁桥的设计方法,对结构的抗弯承载力,抗剪承载力,剪切屈曲稳定性及刚度进行验算。
Prestressed concrete box girder with corrugated steel webs is a new type of steel-prestressed concrete composite structure bridge. It reduces the self-weight that corrugated steel webs are used to replace the traditional concrete web. It has reasonable mechanic property, improves material utilization, shortens construction period, and beatifies the shape. Comparing with traditional prestressed concrete box girder, the prestressed concrete box girder with corrugated steel webs has superiority economy benefit and social benefit. This paper reseaches the design method of prestressed concrete box girder with corrugated steel webs combined with the structure and mechanic properties.
     Based on the axial mechanical characteristics, and the experience formula of flange effective width and the ultimate stress calculation method of external prestressing tendons, the basic formula of ultimate capacity of the prestressed concrete box-girder bridge with corrugated steel webs was deduced based on the beam flexure theory.
     Results from many shear strength tests conducted on girder specimens with corrugated webs are available in the literature wherein both local and global shear buckling modes have been observed. The shear resistant design method of structures with corrugated webs was studied. The calculation method of shear stiffness and the checking computations of shear stress were developed.
     On the basis of design theory for box girder and combined with the structural and mechanic properties of the PC box girder with corrugated steel webs, the Second Theory of A.A.Umanskii was adopted to research on its restrained torsion.
     The deflection of prestressed concrete box girder with corrugated steel webs can not be ignored when considering Shear deformation. The formula of shearing stress of corrugated steel web was presented considering the action of eccentric loads. Using the Timoshenko theories of beam, the flexural formula of box-girder bridge with corrugated steel webs was deduced in view of the influence of shearing deformation.
     In the structural design of prestressed concrete box girder with corrugated steel webs, it is pirotal to design how to connect corrugated steel webs to concrect slabs. Through the statistical analysis of the types of connectors of prestressed concrete box girder with corrugated steel webs. We present design calculation and checking methods of several common connectors between corrugated steel webs and concrete slabs.
     The design and calculational method of prestressed concrete box girder with corrugated steel webs is presented. Its specific design problems are calculation of Section stiffness and checking computations of bending monment, shear and deformation.
