Part of: Approximate Methods and Verification Procedures of Structural Analysis and Design


Simplified computer analyses and various approximate hand calculation methods are extremely valuable in structural engineering for multi-story buildings both during the preliminary design phase and for final construction document member sizing. Simple cantilever and shear frame models with a limited number of variables are presented, corrections for shear deformations in cantilever buildings and some guidelines for member proportioning in high-rise buildings. Finally, energy methods can be used to quickly and efficiently size certain types of buildings and provide valuable insight into structural behavior.
