Investigation On Seismic Behavior Of KP₁ Masonry Wall (Cracked) Strengthened With Steel-mashed Cement Mortar

With the flying development of society and economy, the architecture, industry, the structure reinforcement technique and reinforcement formulation flourish unparalleled. However, the wall strengthening with steel meshed cement mortar has been widely used. Although has been widely used, ect, investigation on seismic behavior (carried out) of masonry wall is still lack of studying on its strengthening effect.Aimed at this instance, we have processed much elementary research on seismic capability and strengthening effect of wall strengthened with steel—meshed cement mortar. An experiment of four KP₁ masonry walls was carried out. the wall was under low cycle reversal load till shear failure and then the cracked wall was strengthened with steel mesh mortar and tested under lower cycle reversal load, The result of the study has testified it an efficient measure to lay steel mesh cement mortar in to masonry brick wall for entirely improving seismic strength. Therefore, base on the experiences, the formulation for calculating the crack load and limit load brick masonry wall reinforced by steel mesh cement mortar is advanced, which provides project reference.Based on the analysis and studies of masonry shearing strength, test of priestessed single brick masonry wall, test of priestessed brick masonry house, and test of wall strengthened with steel meshed cement mortar models, and ect, the article has carried through several aspect research as below:1. Research on influence of loading and destroy of masonry brick wall reinforced by steel meshed cement mortar und low cyclic loading;2. The appearance and development of cracks, failure mechanism, and strength and ductility of the strengthened masonry wall was analyzed.3. The design method of the brick wall strengthened with steel mesh cement mortar is proposed.
