Research On Seismic Performance Of High Shear Wall With Recycled Aggregate Thermal Insulation Concrete

In recent years， with the continuous improvement of the state ofconservation of energy and resources requirement, recycling resource andenergy conservation has become an important breakthrough for buildingresource saving and environment friendly society. And with the continue spreadof our country65energy efficiency standards, Recycled aggregate thermalinsulation concrete combined the technology of recycled concrete and thetechnology of glazed hollow bead concrete, truly achieved a sense of recycledenergy and energy saving in the construction building, and Recycled aggregatethermal insulation concrete played a significant role for alleviating the shortageof resources and exploiting resources damage to the environment. While theshear wall as the main component of high-rise concrete structure, research onthe seismic performance of Recycled aggregate thermal insulation concrete hasan important significant for popularization and application of the Recycledaggregate thermal insulation concrete. The article by researching on horizontallow cyclic load of Recycled aggregate thermal insulation concrete andsimulated by the finite element analysis software, studied the Recycledaggregate thermal insulation concrete high shear wall seismic performance, determined the appropriate axial compression ratio of Recycled aggregatethermal insulation concrete high shear.The main contents include:1.By testing the horizontal low cyclic load of one piece of ordinary shearwall and two Recycled aggregate thermal insulation concrete shear wall,through the test obtained the turn-round envelop curve of load-displacement、skeleton curve、vary stiffness、Ductility factor and Energy dissipation capacityindex，finally obtained the insulation capacity of Recycled aggregate thermalinsulation concrete high shear wall is slightly lower than normal concrete, butthe seismic performance and energy performance is better than ordinaryconcrete shear wall, Recycled aggregate thermal insulation concrete high shearwall can be used as the vertical component in the engineering practice.2.comparing with the axial compression ratio0.14、0.2and0.3of Recycledaggregate thermal insulation concrete high shear wall, but the ductility factorand energy dissipation capacity began to decrease. Through experimentsillustrate that the axial compression ratio has a big impact on the seismicperformance of the Recycled aggregate thermal insulation concrete high shearwall, with the increase of axial compression ratio, the seismic performance、ductility and energy dissipation capacity of the Recycled aggregate thermalinsulation concrete high shear wall gradually reduced.3.By using the finite element software ABAQUS simulation the seismicperformance of the Recycled aggregate thermal insulation concrete high shear wall and did the nonlinear simulation analysis, and the results were agreed wellwith the simulation. Through the comparative analysis can be feasible throughthe simulation seismic performance of the shear wall. By using the finiteelement software ABAQUS simulation the seismic performance of the Recycledaggregate thermal insulation concrete high shear wall with high axialcompression ratio0.4and0.5, obtained that the axial compression ratio of theRecycled aggregate thermal insulation concrete high shear wall cannot exceed0.5,if exceed0.5the seismic properties、ductility and energy dissipation capacityhas adversely affected of the shear wall.
