The design team already won the competition when I joined the team. The project is expected to be built in the next 3 years. One of the biggest changlleng is the cost control on the facade panelization, which aims to subsdivide the surface of various curvature into fewer triangular panels. Based on the study of Soumaya museum, I developed a grasshopper script that use machine learning to divided surface areas that can be and facade consultant ( SV -A ).

Helped my friend at Aecom optimize the script of handrail for construction modular thinking. The original script convey the gradient design intention but don't have control of the value of variation. The new script can manually divide the elements into three - the adjustable constant gap in the middle and the gradient gaps on both sides.

Conditional Loop is applied to express the laguage of gradient.

Before Optimization, the gradient of gap is non measurable for construction ses 4n,a sion 1 +3n ,a+2 n,a

6 A Digital Tectonic of Interlacing / Column Prototype Partner: Luis Medina

Insturctor: Ehsan Barharlou

(GH/KUKA PRC)

This project explores the untold relationships between concrete and soil in conventional architecture construction. Erecting concrete columns often require the excavation of soil for foundational purposes, which results in a surplus of this material. The hybrid prototype rethinks the use-cycle of the soil by reinterpreting its function within both the structural design and ornamentation of the column.

History of Hybrid Columns

Architectural elements have historically been constructed using singular materials, construction methods, and functions within building systems.

For example, columns have traditionally been implemented exclusively aspartofthestructuralsystemofbuildings.Althoughinten design and ornament columns have been set forth from very early ages (dating back to the bronze era in Egyptian architecture, circa 3,000 BC), ahybridizationofbothstructuralerciencyandsecondarypr functionality have rarely been explored. we uses the concepts of “architectural tectonics“ and ‘duality’ as a means of designing and building the hybrid column typology through computation and additive robotic fabrication techniques. Dry-joint, also known as ‘cold joint’, refers to a construction technique that uses highprecision geometries to provide ‘dry’ interlocking connections between building unit layers. The benefits of developing dry-joint connections include, but are not limited to; ease of construction, rapid assembling time, and the non-necessity of wet bonding materials.

Fabrication Process

The mix designs of concrete and earth are studied and applied to joint blocks for the form study. The material ratios are evaluated by the ability to shape the formwork's joint forms and keep the shapes after hardening.Considering fabrication parameters such as robotic movement speed, extrusion rate, and nozzle size, the thickness of the printed formworks is optimized for saving material and time and supporting the formwork structure.

Grasshopper Simulation of the Fabrication Movement

In the workshop held by UVA School of Architecrue Fablab Manager M. Goldman, we used custom tools and ferromagnetic material, developed a construction process utilizing the off-plane toolpaths of a 6-axis industrial robot. The pourable material, ferroresin, forms spikes and connections around invisible magnetic fields, and upon hardening, freezes the field in Particularly, I deisgned a structure that has the capacity to be a joint system unit with the negative sphere edges formed by the custom tool.I developed a script that can show the trace of connections among vertices of two squares made by scale and rotation.

It can be imagined as a symmetrical structure having the form of the 'W' shape and four potential connecting points on the top.

They can be the joints for anything that has sphere edge.
