Abstract：Inorder toreveal thedamage evolution mechanismofstelreinforced concrete（SRC）shear wallunderearthquake actionadimprove itsseismicperformance，thispaper takes SRCshear wallinhigh-riseresidential structureastheresearch object，and carresoutlow-cyclerepeated loading test.During thetest，multi-source monitoring methodssuchas strain， displacement，crack，acoustic emisionand aceleration wereused tosystematicallytrack the mechanical response and damage accumulationcharacteristicsofthewallinthewholeprocessofelasticity，elastoplasticityandfailure.Theresultsshowthatthe middle and upper part of the wall （ 1.5～3.5m from the bottom of the wall ）is the damage concentration area. The maximum tensile and compressive strains of concrete are 1 950、 -2100με ，respectively. The strain of steel exceeds the yield threshold 0 ε±2000με ）. The maximum crack width is 0.55mm ，the interlayer displacement angle is 1/120 ，and the acoustic emission energy release is as high as 296.7mJ .Based on the damage distribution characteristics， optimization strategies such as sectional reinforcementof steel section，reinforcementratio improvementand concretestrength gradient designareproposed.

After optimization，the peak strain of wall concrete is reduced by 17% ，the crack width is reduced by nearly 50% ，the interlayer displacement angle is increased to 1/135，and the acoustic emission energy release is reduced by 47.7% ，which effectively improves the seismic performance and damage control ability of SRC shear wall.
