| The beam-string-structure is an important long-span structure which is known as cheap, reasonable, convenient to transport and install.This structure has been widely used already,but the theory of this structure is still very poor.Machanical behaviour of beam sring structure is studied by ANSYS5.7.The effect of beam string and fitting cabal to deformation and internal force of BBS is analysized in detail.Some conclutions are useful for the engineering. |
