主　　题：Precast column Grouted sleeves Assembled seam Deformation Strength Numerical analysis 

摘      要：Grouted sleeves can effectively connect precast elements,but the effect of grouted sleeves for increased stiffness and assembled seam for weakening stiffness on the precast column’s mechanical properties is *** on the full-scale test results of precast columns connected with grouted sleeves and the correctness of the numerical models,the influence analysis of the individual and coupling action of the grouted sleeves and assembled seam on the deformation and bearing capacity of the precast column is carried *** research results show that grouted sleeves significantly affect the deformation and peak bearing capacity of precast columns;when precast columns are subjected to the action of high axial pressure,grouted sleeves significantly affect the bearing ***,the influence of assembled seams on the peaking capacity of the precast column is more obvious when it was tested under low axial *** is recommended that the connection position should be 2 times the height of the grouted sleeve from the bottom of the foundation.
