Damaged plasticity model - seismic analysis of structure of the Petronas Twin Towers (Kuala Lumpur) in Malaysia
Abstract
The article presents numerical simulations for the modelling of seismic impact on the structure of Petronas Twin Towers (Kuala Lumpur) in Malaysia with application of two methods. The Response Spectrum method, in which a spectrum of the structure's responses to an earthquake's impact is generated and the Acceletogram (BETA) method, in which we generate dynamic load in the form of a diagram of the connection between acceleration and time for the actual readings during a real earthquake. Both methods have been presented for the El Centro earthquake spectrum. The scope of the works also encompasses the solution to the dynamic problems connected with the seismic analysis in which the damaged plasticity model of the structure is taken into account. The process of modelling the boundary conditions as well as the material are really complicated, as once the structure is loaded with seismic load, the material starts behaving in a very non-linear way. This causes significant difficulties in making the model as well as in setting the numerical analysis itself. The conclusion of the analysis will be a comparison of the movement due to flexibility of Petronas Twin Towers skyscrapers' with different ways of spectrum modelling.
