The Analysis Of Steel Truss Transfer Story

Currently, with the rapid development of high-rise buildings , building functional requirements are also increasingly complicated. Because of structural steelwork with a good performance and the strength earthquake performance, structural steelwork in civil construction projects, especially long span structures are increasing broad applications. For a long span transfer story, although clear-edge, clear-channel capability, but structure and construction are complex. There are few actual structures and experiments .For a long span steel truss structure as a transfer story which works in the vertical load, the loads will have greater effects on the ends of the steel truss support structure . The steel truss and steel truss end of the concrete structure will be greatly affected by the different steel truss - border restrictions and conditions. Therefore, the different structural forms of transfer story will be simulated and compared by the progaram sap2000In addition, in order to study in transfer story framework system performance deeply, the framework of two-dimensional graphic model is choosed for static nonlinear analysis . The weak layer location of the system, the sequence of hinges, structure bear base shear and peak displacement are analysed and the impact analysis of the law of the second moment are also studyed. The spectral ability assesses further seimic performance of structure clearly .
