Abstract

Abstract

The blasting vibration effect in the subway excavation process of a multistory masonry building strengthened by shotcrete was analyzed using representative volume element model. Finite element models for both the original structure and the strengthened one were established,and time-history analysis was performed. The effect of shotcrete strengthening on masonry walls was analysed from the structural period,structural stiffness,top lateral displacement and stress level. The result shows that the structural stiffness is effectively enhanced and integrity of the structure is improved. Since the major portion of shear force of the blasting vibration effect in the strengthened wall is resisted by the strengthening concrete layer,the stresses in the masonry wall are reduced and the structural failure is avoided.
