Abstract
Simulation of blasting demolition process of 84m tall frame-core tube shear wall building by using ANSYS/LS-DYNA program. Finite elemet model of reinforced concrete material using elatic-plastic model *MAT_PLASTIC_KINEMATIC, and the gravity is applied by * LOAD_BODY_GENERALIZED*, the setting of FAILTAM term to realize the formation of delay initiation blasting notches. And different blasting delay schemes are designed and the blasting effects are compared. It is of certain guiding significance to reasonably select the blasting delay parameters and predict the blasting demolition effect.
