The intake tower of the hydropower station is a high-rise underwater hydraulic building whose seismic safety is enormously important. Taking the effect of foundation and hydrodynamic pressure into account, we apply the ANSYS for the static and dynamic analysis which evaluate the seismic behavior of the intake tower. The result which provides the basis for the improvements shows that the rigidity of intake tower meets the requirement. After taking some engineering reinforcement measures, the strength also meets the requirement.

Distribution Of Stress

Taking intake tower of Hydropower Station project for an example, ANSYS is used on the intake tower dynamic, static analysis, to study the distribution of stress and displacement as well as structural stability. The results show that, under load, the deformation and stability of the intake tower to meet the structural design requirements, need to take special measures in the weak parts of the internal forces in the structural design. The results in this paper may be served as the basis of structure design of the intake tower.

Two Alternatives

This paper deals with static and dynamic analysis of asymmetric high-rise building. Two alternatives have been analysed – without dilatation and with dilatation. Then, the influence of the dilatation was discussed. The building was located in 4th seismic area in Slovakia (Bratislava). The description of the building, applied load, considered soil-structure interaction, created calculating models, used analysis and obtained results are mentioned here. The conclusions and the photos of defective repairs of real structures are depicted at the end of the paper.

Storey Building

Static and dynamic analysis of the high-rise (24-storey) building is discussed in this paper. The influence of the change of load-bearing system on its stiffness in the case of seismic event was detected. Two different load-bearing systems were chosen – the wall system (alt.1) and the skeleton system (alt.2). Finite element method was used for the solution of 3D computing models. Short description of the building, used material, applied load, a type of the subsoil and obtained results are mentioned. Dynamic analysis was repeated for four various seismic areas in Slovakia.

AbstractIn the present paper, a General Algorithm is applied to the analysis of high-rise structures. This algorithm is to be used as a calculation tool in preliminary design; it allows to define the interaction between closed and open, straight or curved shear-walls, and the forces exchanged in structures subject to mainly horizontal loads. The analysis can be performed in both static and dynamic regimes, the mode shapes and the natural frequencies being assessed. This general formulation allows analyses of high-rise structures by taking into account the torsional rigidity and the warping deformations of the elements composing the building without gross simplifications. In thisway it is possible to model the structure as a single equivalent cantilever, thus minimising the degrees of freedom of the system, and consequently the calculation time. Finally, potentials of the method proposed are demonstrated by a numerical example which emphasizes the link between global displacements and stresses in the elements composing the structure.

This paper presents static and dynamic analysis of tower structure supporting a 600KW wind turbine based on the theory of FEM. According to the static and dynamic characteristics of tower structure, the works about simplified models and confirming loads and boundary condition are discussed. In static analysis, under different work conditions the load bearing capacity of tower structure is analyzed with door opening in different directions and without door opening. In dynamic analysis, in order to address the impacts of the foundation on structure, the research discusses the natural frequency and eigenmode from the first sixth modes at the assumption of fixed base and the elastic subgrade. Comparative studies have been performed on the results of the above analysis and some useful conclusions are drawn pertaining to the effectiveness and accuracy of the various models used in the work. Our research work lays a solid foundation of the further static and dynamic analysis.
