Abstract: A proposed static loading scheme was adopted to conduct low circumferential reciprocating load tests on three pieces of walls, one for a monolithic cast-in-place comparison specimen and two for precast shear walls connected by metal bellows slurry anchors. Acoustic emission tests were conducted to investigate the similarities and differences in the damage mechanisms of cast-in-place and prefabricated as well as shear walls with different axial compression ratios, which were quantitatively analyzed via two types of NDT equipment, DIC and AE, and by using characte-ristic parameters such as b-value, energy, ringing counts, and RA-AF values. Observation of the test phenomena and damage characteristics revealed that: all specimens had corner damage with different degrees. The crack distribution of cast-in-place contrasting specimens was more uniform than the others, and the crack width at the horizontal joint of prefabricated specimens with metal bellows slurry anchor connection was the largest. The sliding time window algorithm was used to reduce the b-value error caused by too little data in a section, thus it can more effectively and intuitively characterize the damage process of the specimens. And higher axial compression ratios brought more rapid and severe damage. The damage patterns of these three specimens were similar, and the bearing capacity of the slurry-anchored reinforced concrete shear wall was close to that of the cast-in-place specimen, which achieved a effect of equivalent cast-in-place.
