Numerical Optimization of Half-Tunnel Concrete Formwork System using FEA

Abstract

This research seeks to develop a comprehensive framework for the design of Half-Tunnel Concrete Formwork System (HTCFS). HTCFS are highly efficient systems that are used for the construction of modular RCC structural systems. Additionally, HTCFS are significant in terms of higher reuse in constructing modular units. Despite these advantages, the actual design procedure adapted for HTCFS was not well elucidated so far, many companies adapt their own design methodology and hence it is highly important to develop a simplified straight forward design methodology incorporating all comprehensive associated factors. Initially, the detail introspective assessment of various types of HTCFS are perceived. Then using this information, a 3D Solid model is developed, and eventually, the 3D model gets converted into 3D solid CAE model using sophisticated Finite Element package for the Finite Element Analysis (FEA). This procedure is repeated for different combinations of components that construed effective systematized HTCFS. From the FEA the optimal structural components required for the structural integrity of HTCFS are established.
