Application of strengthening method by changing force′s transfer road in engineering

Upon strengthening a landing stage, this paper introduced the application of strengthening method by changing force′s transfer road in engineering. The original structure is a plane frame. The cracks appear in some members because bending strength of them is not enough. By jointing two supplementary plane frames into an integrated three dimensional frame, the road of original force′s transfer is changed. The load stresses of the members, in which cracks appear, are increased and meet the demand of safe. At the same time, the members whose load stresses are increased are safe too.
