Abstract
A support structure of a motor bus comprises a plurality of modular cells each comprising two rectangular end frames made up of two channel section uprights and upper and lower channel section crosspieces, the channels facing axially away from the other frame and having flanges for welding to corresponding members of a contiguous frame of an adjacent modular cell in the structure. Longitudinal reinforcement is provided by longitudinal members at the upper corners which together form a box-section stringer and by channel section stiffeners joining the lower crosspieces. A corrugated panel overlies the lower crosspieces and is joined to them.
