Comparison of stress graphic reinforcement calculation methods in various design codes for hydraulic concrete structure s
摘要
Abstract
The evolution of the stress graphic method in four kinds of design codes for hydraulic concrete structures is introduced, and the reinforcement calculation formulas in different codes are compared and analyzed in this paper. Reinforcement calculation was conducted in practical engineering projects, including a bearing plate, a flood-discharging deep orifice, and the upper lock head of a ship lift. The calculation results are as follows:In the code SL 191-2008, it is recommended that the maximum proportion of the tensile force that the concrete can bear to the total tensile force be less than 15%, rather than 30%. After the code SL 191-2008 is revised, the amount of reinforcement by the code SDJ 20-1978 is the largest, the reinforcement by the code SL 191-2008 is moderate, and the reinforcement by the code DL/T 5057-2009 is the smallest. When the bearing plate, the flood-discharging deep orifice, and the upper lock head of the ship lift are regarded as plane problems, their amounts of reinforcement by codes DL/T 5057-2009 and DL/T 5057-1996 are close, with a maximum difference of only 4. 1%. When the effect of temperature is not considered, the tensile force that the concrete can bear is usually zero, and we can increase the amount of reinforcement to limit the crack width.关键词
