SIMPLIFIED BUILDING ANALYSIS WITH SEQUENTIAL DEAD LOADS - CFM

Abstract

The effect of the sequential application of dead load due to the sequential nature of construction is an important factor to be considered in the multistory frame analysis. Unfortunately, however, this effect has been ignored by many engineers in practice in the past. One of the ways to include this effect properly in the analysis is to carry out the analysis through step-by-step procedures in accordance with the sequential application of dead loads as the construction proceeds. These procedures, however, require elaborated computations and more solution time. A simplified approach, termed as correction factor method (CFM), to solve the problem without elaborated step-by-step analyses has been proposed in this paper. This method utilizes the correction factors established by regression from the data obtained from the existing buildings to modify the results from the ordinary analysis to produce more accurate solutions. Some numerical tests are presented to show the validity and effectiveness of the method.
