Engineering Practice of Overlong Jointless Transfer Structures

对某超长转换结构进行了无缝设计,采取了箱形梁转换形式,框支转换梁采用了有粘结预应力技术。采用SATWE程序进行结构整体计算后,再用ANSYS程序对转换层进行了细部有限元分析,二者的计算结果基本吻合。介绍了结构的基本形式、构件截面和布置、框支转换梁的内力计算、设计和主要构造措施。

Jointless design method is used for an overlong transfer structure. The box section transfer beams are chosen, and the technique of prestressed concrete with bond is used. The integer structure is calculated by SATWE software, and the native forces of transfer beams are checked by the finite element software of ANSYS. The calculating results agree with each other well. The section and collocation of the members, the calculation and design of the transfer beams, and the main construction measures are introduced.
