Module 3 – Gerber Roof Girders
Design Module 3 covers the design of roof girders in Gerber construction. Design tables are provided to assist designers in selecting the cantilever girder and drop-in segment sizes for typical building applications with evenly spaced columns and joists. The tables are applicable to flat roofs subject to dead, live, snow and vertical wind loads. Various girder and joist span combinations, lateral bracing configurations and load conditions are included. Solved examples are presented to illustrate practical applications.
