Virtual Reality and simulation software could be so helpful to predict the motion of components with regard to stability. The use of Virtual Reality provides information through Vive Headset devises to analyze Kinetic Façade.

12. Case study
We investigate geometry of Al bahar tower which is famous kinetic
project due to implication Hexagonal and triangle geometry. The
analyzed module is composed of six “micro-triangles,” and is such that
its boundary forms a “macro-triangle” when projected onto a plane
parallel of the building façade (umbrella-like module). The activation
mechanism of the TABS module is driven by a linear actuator, which
stretches the perimeter strings, by pushing against a vertex of the
macro-triangle along its bisector, in parallel to the building façade.

13. The module is described as a tensegrity system formed by 3 strings parallel to the building
façade and aligned with the edges of the macro triangle (red-colored members), and 12
bars forming the edges of the micro triangles (black-colored members). The TABS model is
formed by seven nodes (numbered from 0 to 6)

17. The Karamba plugin establishes the relationship between the parametric model and the behavioral
simulation of the structure by applying identifying codes. Using this tool, the stability behavior and
turbulence behavior of the structure can be investigated in exchange for changing the parameters applied to
the model geometry.
Mindesk is the first real-time platform
that provides us for immersive reviews
or within Unreal Studio for top-quality
real-time renders.

To investigate the impact of geometry parameters on Kinetic façade
with applying Virtual Reality that is the state art of technology for
simulation.

First, the number of supporters is fixed on the grid with different
positions of connections.
Second, various number of supporters with different lengths of the
connector.
Results:
To extend knowledge and creative about details of kinetic structure and
mechanism of movement underlying technology such VR
• no need to design for moving large part of buildings
• to reduce high cost and complexity in implementation
• to achieve to dynamic and kinetic façade with functional and logical
reasons
