The tests of five specimens with different axial compression ratios and different cross-sections are completed under the action of reciprocating horizontal loads. The restrained edge members of the seismic walls are tested according to the Code for Design of Seismic Design of Buildings (GB5 0 0 1 1-200 1) Set, distribution of cold-rolled ribbed rib welded steel mesh. The maximum tensile strain of the cold-rolled ribbed bar with vertical distribution was calculated and analyzed when the ultimate compressive strain of four edge concrete with restrained edge members and edge members was calculated. Degree) The elasto-plastic time-history analysis of the earthquake-proof wall structure with distributed ribs by the cold-rolled ribbed steel welded net is carried out. The results show that the earthquake-resistant wall can meet the seismic requirements through the rational design of anti-seismic walls using cold-rolled ribbed steel welded webs as distribution bars. On this basis, the design suggestions of the anti-seismic wall of cold-rolled ribbed steel bar welded net are given
