In the design and construction of a long beam, considerable attention should be paid to its deflection. This paper discusses a method that minimize the beam deflection by successfully utilizing the composite effect of steel beam and concrete slab. The camber of the beam to cancel its deflection can be reduced, if the beam is temporarily supported at several points until the achievement of composite effect. The error of the camber can be moreover adjusted by pushing up the supports. Also presented is a practical application of the method to the long span crossed beam in a highrize office building.
