Building comprising prefabricated composite panels with rigid structural frame

A method for constructing a building having a perimeter, consisting of the following steps:

• providing a slab,
• providing a plurality of vertical posts having first or bottom and second or top ends,
• providing a beam having opposing vertical sides that face in opposite horizontal directions,
• providing a plurality of wall panels, and
• providing a plurality of roof panels for enclosing said building structure above said wall panels, said roof panels being secured side-by-side to one-another to form a flat or planar roof that has opposite ends at said perimeter, said roof panels also being secured to said wall panels,
• securing said first or bottom ends of said posts to said slab at opposite ends of said perimeter,
• securing said beam to said second or top ends of said posts, said beam extending between said second ends of said posts, said beam and said posts forming an inverted-U-shaped support frame for supporting said wall panels and at least some of said wall panels,
• securing said wall panels to said slab along said perimeter so that said wall panels extend around said perimeter, and
• securing said roof panels to said wall panels,
• securing said beam to said flat or planar roof, said beam of said U-shaped frame underlying and attached to said roof, said vertical sides of said beam spaced from said respective opposite ends of said roof,
• whereby after joining, said slab, said frame, said wall panels, and said roof form said interior space of said building structure and said frame stabilizes said building.
