Abstract

The invention discloses a method of computing reinforced concrete creep stress which obtains constraint factors reflecting the actual constraint status of a reinforced concrete structure according to the rebar stress actually measured by a rebar stressometer and further finding the relationship between the reinforced concrete creep stress and the rebar stress. Compared with the method of obtaining the concrete stress through complicated mathematic changes by using buried complicated strainometer and non-stressometer in the prior art, the invention has the advantages of higher accuracy and economy. The invention provides powerful reference for reflecting the status of the internal force of the composite material reinforced concrete and evaluating the safety of the reinforced concrete structure.

Description

technical field [0001] The invention provides a method for measuring the creep stress of reinforced concrete with a steel stress gauge in a reinforced concrete structure, which is suitable for measuring the creep stress of the reinforced concrete structure under external force load, temperature load, autogenous volume deformation, creep and dry shrinkage load Measurement. Background technique [0002] Reinforced concrete structure is a commonly used structural form in civil engineering such as water conservancy, hydropower, transportation and industrial civil buildings. This structure is composed of two materials: steel bar and concrete, which can give full play to the tensile capacity of steel bar and the compressive capacity of concrete. , has a high carrying capacity. Since the reinforced concrete structure is composed of steel and concrete, in addition to the stress generated by the external load, the difference in the thermal and mechanical properties of the steel and ...
