Thats how monocoque airplane structures are built, most of the load is in the skin, the stringers and ribs are there to give shape and pass the loads from one skin to the next.....Tim
exactly what i was thinking!i think two staggered rows of rivets onthe the front ,rear and lower door seem would tie the car together very well.a buddy of mine builds derby cars and swears by welding the trunk all the way around and ovaling the mounting holes in the fenders to push them in untill the hood will bearly shut.i think it would be a lot more than trivial support.think about what subframe connectors do for the feel of a car.i feally think the structurall flaw in cars is the big hole in the side leaving only the roof arch for support.
once i scrapped a duster body and decided to cut the roof off to seewhat a duster convertible would look like (cool as hell! btw).you could then stand in the middle of the floor and use the car as a trampoline with the doors open.  .so i was thinking hmmmmmmmmm

The problem with that experiment is that the roof is actually the major structural member in a unibody car. Simply riveting sheet steel in place of the doors, while it would help, would not replace the integrity you lost with the roof. Similarly, unless you have a Jeep, rarely do you see cars driving around without doors. The doors are structual members and all the sills, latches and hinges are integral components.
Also, airplanes and monococque racing bodies are designed with integrated components to support structual loading. A automotive uni-body has to make concessions to asthetics and design, so it cannot function in truly the same way. It requires some sort of additional structural members to support not just the skin, but all the various loads applied to it. This is why there are spaceframes and subframes built in to unitized construction. All those folds and bends and bulkheads we find annoying when building a car, actually are integrated support members.

to me the cup is half empty,removing the roof only shows how much support the rest of the structure does not have.
anybody ever notice that a four door abody or b body always feels stiffer than its counterpart two door?
i cant think im crazy,for god sakes people go nuts over finding post cars for drag racing as if that little strap of metal between the windows makes a big differance.
