Abstract

The invention provides a reinforcement method for a pressed steel plate with continuous elliptical holes. The method includes the steps that (1) according to the geometric dimension and the material characteristic of the plate with the elliptical holes, namely the perforated plate, the pressure strength limit of the perforated plate after drilling weakening is calculated; (2) a proper reinforcement mode and a proper reinforcing plate dimension are selected according to the geometric feature of the perforated plate and the actual engineering requirement; (3) the pressure strength limit obtained after reinforcement is calculated according to the formula; (4) the strength of the reinforced perforated plate is checked, and if the strength does not meet the design requirements, the step (2), the step (3) and the step (4) are carried out repeatedly until the strength obtained after reinforcement meets the design requirements; and (5) the reinforcing plate is welded to the perforated plate as required. The reinforcement method is reliable theoretically, clear logically and simple.

Description

technical field [0001] The invention belongs to the technical field of steel structure design and construction, and in particular relates to a reinforcement method for a pressure steel plate with continuous elliptical holes. Background technique [0002] Steel bridge towers have the advantages of small size, light weight, good seismic performance, and short construction period. In recent years, with the successive completion and construction of bridges such as the Tingjiu Bridge in Hong Kong, the Third Nanjing Yangtze River Bridge, the Taizhou Yangtze River Bridge, and the Ningbo Bund Bridge, steel bridge towers have been more widely used in bridge construction in my country. Compared with concrete bridge towers, steel bridge towers can be made lighter while meeting the same bearing capacity. They are manufactured in factories and then assembled on site. The construction is convenient and fast, and the construction period can be shortened. Although the engineering cost of s...
