Workshop Project - Group Work

Location: Science and Technology Park of University of Tehran,Tehran, Iran

Supervisors: Arman KhalilBeigi, Esmaeil Mottaghi

One of the main objectives of this project was to create a monument to act as a social hub or attraction point to stimulate multi-disciplinary dialogues and encourage interaction among different teams in the technology park. By running a computer simulation, suitable locations were selected, and BaseNodes for geometry was chosen based on this heatmap. An interconnecting network was established on this set of points, which was further adjusted in node-valance, connecting topology, and architectural necessities, and then a 3D network was then generated using an ‘Incremental loading’ procedure.

Contribution To The project

Participating in Digital Fabrication Process Photography

Form finding based on structural analyses

Primary line network

Fattening base elements based on material properties

Subdividing the base form in Wrication method

Design process

This form-finding process ensures that the resulting form will undergo Compression forces only (in case of applying dead loads) and improve this process. A ‘Dynamic relaxation’ method was also combined with that, which firstly relaxes nodes and moderates the angels and secondly uses different masses for each node, enabling the control of the geometry intuitively to comply with architectural requirements.

The primary issue in this project is to propose a method to fabricate elements numerically.

Any proposal should have these properties:

1. Precision, to make sure minimum deviation occurs in concrete moulding and assembly

2. Efficiency in minimizing material waste on moulds, minimizing cost and time of 3D CNC machinery.

Eventually, a hierarchical system of steel members developed inside each element and fulfilled our aim. These steel members: a) are designed to be fabricated using standard 2D laser cutting CNCs. b) per-form as arming bars in ordinary concrete elements to bear tension forces and c) orientation of these members ensure that the outer shell is fabricated correctly, thus rectifying any inaccuracy of outer mesh

Technical study

This simple 3D network generates a varied mesh, with different radiuses related to a) Forces in each element and b) Concrete construction limits. This basic mesh was appropriately segmented to allow the structure to be disassembled and reassembled. Because each state of the subdivision is intimately tied to the location and orientation of other connecting [steel] pieces, this subdivision process was done recursively. As a result, not all potential subdivisions were realistically valid. This step presents the most critical issue in this project: to suggest a way for numerically fabricating these pieces. Any proposal should contain the following characteristics:

1. Precision, to make sure minimum deviation occurs in concrete moulding and assembly

2. Efficiency, in terms of minimizing waste of material on moulds, minimizing cost and time of 3D CNC machineriesEventually a hierarchical system of steel members developed inside each element that fulfilled the above statements. Thesesteelmembers, a)a redesigned to be fabricated using typical 2D laser cutting CNCs. b) perform as arming bars in ordinary concrete elements to bear tension forces and c) orientation of these members ensure that the outer shell is fabricated correctly, thus rectifying any inaccuracy of outer mesh
