<p>A building frame resistant to earthquakes, gale-force wind loads, fire, insects and rot includes a peripheral frame wall constructed of rectangular steel tubing. Side wall frame modules (46) bolted together along adjacent edges, and end wall modules bolted together along adjacent edges and to the ends of the connected side wall modules form the peripheral frame wall. Diagonal bracing is built into selected side and end wall modules as require d for the desired degree of wind resistance. Trusses made of various size tube such as 2X3 inch rectangular steel tubing for supporting a roof, including a hip roof, on the peripheral wall, are assembled and welded in a welding shop and the prefabricated trusses and wall modules are trucked to the building site. Multiple stories may be erected and fastened together by anchor bracke ts arranged bottom-to-bottom above and below the second and higher floors. The building frame is secured to a foundation by attaching the anchor brackets t o anchor bolts set in the foundation.</p> |
