| Abstract: | On the basis of the research and practice which we had done about the design of opening big holes in the web of steel box girder, this paper inquired into several questions of theory and major design details about the design of opening big holes, to satisfy the requirement of passing men and installing machines, in the web of large box-arm which is the backbone-structure taking loads of the heavy-duty crane, such as the track-laying or bridging machines. As a result of these, the method of design and analysis is simple, clear, depdndable and well-practicable, so that it is unnecesary to require the computer programs, and only manual computation would be easy to achieve the results which are rather rational and optimization. |
