Static Analysis of Climbing Formwork System for High-Rise Building Construction

Abstract

The prime objective of this research is to develop a comprehensive framework for the static analysis of crane-dependent climbing formwork system. In this research, one of the climbing formwork systems that are commonly used for the construction of high-rise buildings known as crane-dependent is contemplated. Initially, suitable design intends of the climbing formwork system are discerned from the literatures and formwork technical reports. Additionally, various other factors influencing the analysis of the climbing formwork system are taken from the real-time construction projects. Using these information a suitable 3D finite element model of the climbing formwork system is developed. The 3D model is then analysed using a superior finite element program. The result shows significant variations in terms of deflections and stress contours. Notwithstanding the application of the real-time parameters for the analysis of climbing formwork system, the results obtained are haphazard. To overcome these shortcomings and to apprehend the situation of lack of codal provisions for the analysis of climbing formwork, a sophisticated soft computing methodology, known as Genetic algorithm is trailblazed. The optimal parameters obtained from the Genetic algorithm is then used to formulate the modified 3D finite element model. The results of the modified 3D finite element model depicts the actual behaviour of the climbing formwork system in the real-time scenario. This research portraits the comprehensive procedure for the analysis of climbing formwork systems.
