This passage analyzes and compares structural form of crane-room scientifically based on characteristics of crane-room in glass industry buildings,introduces steel-con- crete structural plan layout and joint construction and bear- ing-force behavior.

Unitip the rof surport bracket and the crane truss for demotishop cotumn in the light-steel workforms with protal frames the method of that desigh and calculation were intrduced in this paper.

According to the contrast of the three schemes, such as crane truss, welding I-shaped crane girder and welding box-section crane girder, the design scheme of box-section crane girder is adopted by con sidering with the economy and the safety.
