Abstract: |
In the design a car of the parking building,the vehicle load is usually evenly distributed to the structure in the form of live load.In fact,due to the random parking of a vehicle,the overall center of mass of a parking building structure is offset.Once such a structure encounters an earthquake,the randomness due to vehicle parking may cause torsional damage to the structure.In this paper,the randomness of vehicle distribution is considered on the basis of traditional shock-absorbing design methods,and the probability of collapse of the shock-absorbing structure under the action of large earthquakes is analysed from the perspective of reliability.The results show that the collapse probability of the shock-absorbing car parking building is 0 and 2.47% before and after considering the randomness of vehicles with the same shock-absorbing design layout.Therefore,the traditional shock-absorbing design method that does not consider the random parking of vehicles actually overestimates the seismic performance of the structure,and the structure of the shock-absorbing parking building still has the risk of collapse under the action of large earthquakes. |
