| Abstract: | The disintegration form of tall buildings, impac energy of tall building to the ground and stress wave propagation in the media are analyzed on the basis of engineering evolution.According to the relationship between the structural parameters of construction and designed blasting parameters, a mathematical model for particle vibration velocity of collapsed tall building is given under specific condition. The mathematical model, which is in more favor of engineering practice by comparison with previous empirical formula, provides definite theoretic foundation for future analyze of predication and control of vibration effect of collapsed tall building. |
