| Abstract: | Based on elastic theory,three kinds of calculating methods of the maximum impulsive force ( P max ) that collapse building shocks surficial soil are put forward in different views, and their results are consistent well. P max is related to the mechanical parameters of collapse building and surficial soil, and the mass, the shape and the falling height of collapse building. The method 3 has wider adaptation advantage because of its character that different P max corresponds different shape of collapse building. These studies are expected to supply theoretical basis for calculating P max and protecting in practice. |
| Keywords: | collapse building maximum impulsive force method of calculating |
