Dynamic loading on a prefabricated modular unit of a building during road transportation

Abstract

Modular building construction is an emerging trend in the construction industry. During the course of road transportation of the modular unit of a building, vehicular vibrations on the truck-trailer may cause damage to components that are attached to the unit. The amount of dynamic loading depends on many parameters including the level of loading on the vehicle, location of the centre of mass, suspension setup of the truck-trailer, and amount of damping of the vibrating parts. The effects of these parameters on the vertical motion of the trailer-chassis are the focus of interest in this study. The acceleration response spectrum representing the filtering effects of the suspension system and ..
