51 Multi-Span Hinges Bent Internal Force Calculation Method

Single factory building is often used the structure of multi-span hinges bent, which made of roof trass, column and foundation. The connection of column top and layer frame is the welding of embedded parts, it can regarded as hinges, the column base and based are casted together, it can regarded as rigid connect. according to the angular displacement equation, multi-span hinges bent equal section column internal force calculation method and the equivalent sidesway rigidity of staircase column were studied. Lastly, the staircase axis internal force calculation method which based on the equivalent sidesway rigidity of staircase column calculation method is established.
