Abstract A high tower can be strengthened by adding a series of diaphragm bracings. This paper analyzes the working performance of high tower added diaphragm bracings through the method of three-dimension finite element considering geometry non-linearity and material non-linearity. Meantime, this paper also implements the optimization of the selection of connections and the parameters of diaphragm bracing's location. The result shows that the intensities of resisting bending and twisting are highly improved by utilizing diaphragm bracings. This scheme has already been applied to practical improvement projects and has been proved feasible.
