Abstract

A multistory factory building with elevated access allows loading and unloading of the raw materials and finished products right in front of each factory unit. This enhances the land productivity of landscarce Singapore. However, container trucks traveling within the building may cause vibration of a production floor where high-precision equipment is located. In this study, a dynamic vehicle model is established to simulate a 40-ft container truck. The road roughness is represented by a power spectral density function according to ISO 8606. The random response of a typical production floor is analyzed by the fully coupled vehicle-structure interaction method as well as the decoupled moving dynamic nodal loading method. Compared with the acceleration and velocity acceptance criteria, the random response results show that the vertical response of the production floor to the container truck traveling at 15, 30, and 40 km/h over road classes B and C is generally acceptable. However, the maximum vertical vibration may exceed the more stringent criteria for some extremely high-precision equipment.
