| Recycled aggregate concrete (RAC) is get through recycling, crushing,screening the waste concrete block to get recycled aggregate, and then mixingrecycled aggregate with a certain proportion.Recycled concrete technology makes itpossible to reuse the construction materials resources and protect ecologicalenvironment.Based on extensive research on domestic and foreign literatureof recycled concrete, the material properties and structural performance ofrecycled concrete is discussed. The latest progress of the recycled concrete isintroduced,including recycled concrete structure filled steel tube.Through test of recycled concrete and concrete members subjects to bend andshear members under low-cyclic loading，their failure mechanism,as well as theseismic behavior of the hysteresis curve, the skeleton curve, ductility, stiffnessdegradation, energy dissipation capacity is discussed. Recycled concrete memberssubjected to bend and shear is similar to concrete members subjected to bendand shear in failure mechanism，ductility, energy dissipation capacity. Refering totest data and relevant research result，the shear formula of recycled concretebeam is suggests.Finally, recycled concrete and concrete members subjected to bend andshear by a non-linear method was analyzed through the finite element softwareABAQUS.The simulation results reflect the test results to a certain extent.The comparision analysis of the recycled concrete and concrete memberssubjected to bend and shear can provide a reference for future similar study. |
