Seminar + Workshop “Design through Systems Thinking Informed by Materials” . 01

I gave a seminar and run a workshop* titled “Design through Systems Thinking Informed by Materials” at the Istanbul Technical University, Graduate School of Architecture as a part of the course Computer Application in Architecture.

AIM:

The proposed approach aims to create a method based on systems thinking by referencing nature in order to generate a funda­mental base of computational design. Students should explore design through material systems in a holistic manner. By integrating systems thinking to the design process, in which the rules and relationship among system elements are defined at the beginning of the design process, most efficient solutions are generated by the system itself. Students are asked to test this method on a façade solution.

Architectural Geometry Informed by Static and Dynamic Loading Conditions. 03

The surface (F= sin (β)+ cos (μ)) is restrained on the ground and a vector force of 10 000 N in Z direction is applied to the peak point of the geometry. The maximum equivalent stress varies from 78373 PA to 83404 PA for different panelization methods by the use of steel as material.

Computational Fluid Dynamics (CFD) is operated on the surface (F= sin (β)+ cos (μ)). The graphical display represents contours of static pressure, velocity vectors and path lines in given the boundary conditions. The wind flow is aligned with the velocity vectors.

 

Architectural Geometry Informed by Static and Dynamic Loading Conditions. 02

Different panelization options are generated via the code for the geometry with the assigned curve function:  F= sin (v)+cos (u). The script*  performed at RhinoScript platform. Because planar quadrilateral panels obtain advantage of having a lower node complexity and are feasible for manufacturing, planar quadrilateral panels are operated for the geometry. The code enables that the architectural designer can identify if the geometry contains any holes. If yes, then the shapes of them needs to be defined. The algorithm runs with the following procedural steps which the user needs to identify during the execution of the code:

  • Selecting the NURBS surface.
  • Defining the U and V values of the surface.
  • Specifying types of holes if exists any.
  • Introducing the shapes of the holes.
  • Defining the percentage of the holes within overall panels.
  • Deciding if the hole sizes vary or not.

Form Active Structures. 05

Finite Element Method analysis is undertaken for:  (a) Equivalent stress (b) Total deformation (c) Directional deformation (d) Shear stress

The video of total deformations can be watched in the following link: https://www.facebook.com/pages/ParaMaterial/161745380551435#!/photo.php?v=10151103382082060

Mechanical properties of the structural steel.

Form Active Structures. 04

(a) A vector force of –10.000 N is applied  (b) By imposing the boundary conditions, it is critical to indicate the surfaces where the geometry sits on the ground, besides assigning the architectural material, structural steel.

Form Active Structures. 03

(a) Surface curvature analyses are undertaken to identify problem areas by running gaussian and mean tools. (b) The double-curved surface is subdivided into components where quadrilateral panels are assigned to the points on divisions of the x and y directions (U-V curves).

Multipurpose Hall Design. 01

DESIGN INTENT

The Multipurpose Hall Project is located in Istanbul. The intent is to provide a new cultural hub for the city. What ParaMaterial interested to explore is the relationships between material, performance & form and interpret this decades’ paradigm of Parametricism.

The building responds entirely to the geometry of the site which is irregular and also to programmatic requirements of the project brief. The design of the hall, as a continuous volume, and the facade are generated via computational design tools.  

The hall which accommodates 1000 seats is designed for various activities including concerts, theatre and dance performances. The building includes additionally side facilities such as an exhibition hall, educational centre, cafes, management and technical facilities and carparks. The volume of the hall becomes the main design element which is also the structural backbone of the building.

MATERIAL SYSTEMS // WOOD AS ANISOTROPIC MATERIAL

Material systems are able to inform the architectural design process along with computational design tools. In this approach, the concepts of material, performance and form are inter-dependent and equally important, unlike the common architectural design process. In this project, material systems are the main driver of the design system.

Anisotropy is a material’s directional dependence of a physical property. Wood is a anisotropic material of which properties vary based on the directions of natural fibers of the wood. It has the ability to bend in parallel to its fibers. Because of this particular material property, it is feasible to clad the Multipurpose Hall which has a curvilinear geometry with wood strips. The steel frame system is used as the structural system.

In order to extent the concept of continuity driven from the fluid geometry of the interior, steel panels with gradient effect is applied to the facade. The panels can rotate along their pivots to increase/decrease the visibility on the facade based on programmatic distribution.
