ABSTRACT
Consistent with the advanced technology and recent development in building technology,
various shapes of high-rise buildings with light weight and highly strength materials are being
used nowadays. However because of the slenderness, these buildings are becoming more
sensitive and susceptible to the wind actions. The possibility of wind actions such as vortexinduced
oscillation, acceleration and lateral displacements at the upper levels, swaying at the
top and many others may occur. In order to minimize these problems, the response of highrise
building due to the wind actions should be determined. With regard to the current status
on the use of Computational Fluid Dynamics (CFD) technology in wind engineering that has
become a popular tool for engineers in wind pressure prediction, thus this method of
application in the response analysis is investigated. This paper presents the study on the wind
and structure interaction using simulation modeling via multiphysics FEMLAB software. Two
modes of simulation method will be used in this modeling i.e. chemical engineering mode
using CFD code and structural mechanics mode using Computational Structural Dynamics
(CSD) code. Both modes of simulation are carried out using partial differential equations
(PDE’s) based on the finite element method (FEM) of discretization. Simulations on the wind
flow distribution around a single plate model representing a rectangular high rise building are
first carried out, followed by the response of the model in terms of displacements in structural
mechanics mode. The wind-structure interaction response of the model can be obtained from
the time dependent simulation. The predicted results from this simulation are then compared
with other researchers for validation.
