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.

The oil-immersed transformer tank is an outside package component of the transformer body. The sealing quality and mechanical strength of the oil tank are affected by the deformation after loading. In this paper, the 3D finite element model of oil-immersed transformer tank is established. The oil-immersed transformer tank deformation is obtained by FEA under the condition of vacuuming. A series of experiments about the deformation of the oil-immersed transformer tank are carried out. Comparing experiment results with FEA results, FEA results are agrees well with the experiments’. It can save the time consumed on designing the oil tank, and has the directive function for the whole design.

The design methodology based on the planning of experiments and response surface technique has been developed for an optimum placement of Macro Fiber Composite (MFC) actuators in the helicopter rotor blades. The baseline helicopter rotor blade consists of D‐spar made of UD GFRP, skin made of +450/‐450 GFRP, foam core, MFC actuators placement on the skin and balance weight. 3D finite element model of the rotor blade has been built by ANSYS, where the rotor blade skin and spar “moustaches” are modeled by the linear layered structural shell elements SHELL99, and the spar and foam ‐ by 3D 20‐node structural solid elements SOLID 186. The thermal analyses of 3D finite element model have been developed to investigate an active twist of the helicopter rotor blade. Strain analogy between piezoelectric strains and thermally induced strains is used to model piezoelectric effects. The optimisation results have been obtained for design solutions, connected with the application of active materials, and checked by the finite element calculations.
