The invention discloses a device and a method for studying the performance of a steel pipe concrete bending member under load and corrosion conditions, and belongs to the field of structure engineering. The device comprises a loading device, a corrosion device and a measurement device, wherein the loading device mainly comprises a jack, a large (small) supporting seat, a pull rod (with a nut), a distribution beam, a loading beam and a counterforce beam; the corrosion device mainly comprises a corrosion tank, an upper cathode plate, a corrosion solution, an insulated layer and an external power supply; the measurement device mainly comprises a load sensor, a mechanical dial indicator, a small flat plate and a connecting rod. According to the device, the long-term load and electrochemical corrosion effects on the steel pipe concrete bending member can be achieved at the same time; an electrochemical corrosion process is adopted, so that the corrosion speed is higher than that in a natural environment and the test progress can be accelerated; test data obtained through an initial loading stage, an electrochemical corrosion / long-term loading stage and a destruction loading stage can be used for drawing a bending moment-midspan deflection stress whole-process curve.
Description
technical field [0001] The invention belongs to the field of structural engineering, and in particular relates to a device and a method for studying the performance of a steel pipe concrete flexural member under load and corrosion. Background technique [0002] Steel pipe concrete is a kind of composite structure, which refers to the structure formed by filling concrete in steel pipes and the two materials are jointly stressed. According to the arrangement of steel pipes, it can be divided into solid steel pipe concrete, hollow interlayer steel pipe concrete and centrifugal steel pipe concrete, etc.; according to the cross-sectional form, it can be divided into circular, square / rectangular, polygonal and special-shaped steel pipe concrete, etc. Concrete filled steel tubes often bear large loads in actual engineering, and are also corroded by corrosive liquids or gases in the surrounding environment. The above problems cannot be ignored in engineering design and application, ...
