Speedy Construction of Reinforced Cement Concrete Work in High-Rise Buildings by Optimizing Shoring and Reshoring Levels Using Genetic Algorithm
Publication: Practice Periodical on Structural Design and Construction
Volume 25, Issue 3
Abstract
Multistory building construction projects involve time and economy considerations. In this study, an approach to determine a time-optimized solution for speedy construction using a genetic algorithm for a multistory building is used. An objective function is formulated for minimizing the reinforced cement concrete (RCC) work duration, subject to certain constraints, ensuring the practicality and safety of the construction. The solution provides the minimum number of levels of shoring/reshoring that would ensure the least RCC work duration and safe construction. It is found from the study that a total of five levels of shoring/reshoring can ensure safe construction of a multistory building, while keeping the RCC work duration at the minimum, and thus ensure speedy construction. It is also observed that the M45 grade of concrete provides an acceptable shoring/reshoring combination for speedy construction with due consideration of safety. It is recommended that a minimum M30 grade of concrete should be used for speedy construction when the minimum factor of safety requirement is 1.3.
