Aeroelastic Revision of an Atypical Geometry Building through One-way Fluid-structure Interaction Model

2 min read

Aims: On this work, a methodology that solves the one-way fluid-structure interaction problem approach is presented. This methodology is applicable to any building’s geometry, nevertheless, in order to develop a solution, it was proposed a building with a geometry not considered in most of the design codes of structures under wind pressures. In order to compare the results of this methodology a tall building model (CAARC model) widely studied by different authors is also analyzed.  Place and Duration of Study: Graduate Engineering Department, Universidad Autonoma de Queretaro, Queretaro, Mexico. January 2017 to October 2018.  Methodology: First of all, two computational fluid mechanics models were developed in order to obtain the pressures of the wind around the two buildings proposed in a dynamic way. Later, the obtained dynamic pressures were transferred according to the load transfer method on the Structural Mechanical Building model through time-history analysis solved by means of a direct integration method to obtain the dynamic aeroelastic response of the structures.   Results: The dynamic aeroelastic response for both models is obtained.     Conclusion: This methodology does not present any restriction in the model’s geometry and leads to analyze important aspects for the structural analysis such as state of stress of the structural elements and structure displacements, accordingly, the method is suitable for structures under wind pressures that are not considered in the codes. The results obtained through this methodology present a good approach to those obtained by means of fluid structure-interaction models.
