拼装式H型钢钢混叠合梁桥的设计思路及计算

Design and Calculation of Segmental H-formed Steel Concrete Composite Girder Bridge

为了解决建造城市高架道路而影响了相关地面交通这一现象,在设计上寻找解决的办法。选用的叠合梁构造充分利用了混凝土的抗压和钢的抗拉特性。由于钢材容易做到工厂分割、现场拼装,因此采用底钢板的构造,既能充当模板,又能在桥面板和主梁中起作用。

To alleviate the impact on the related ground traffic during construction of the viaduct in the city, solutions are found in the design, i.e. selection of the composite girder making full use of the high compression of concrete and high tensile of steel, As steel is easy for factory process and site assembly, the structure with the bottom steel plate can be used both for the formwork and for part of the deck and main girder.
