THEORIA
Abstract Machines help to nurture a logical thinking process to build developing systems in architecture. The design brief involes application of rules and principle from the respective precedents so as to investigate its parameters. With supportive maquette models, experimenting the materiality and inputs from computing programs, these parameters or variables can be controled and its design can be deduced. Further, iterations are developed for one set of system in detail. The Documentation holds the development of the first semester on Abstract Machines Studio at Leeds Beckett University 2016.
Curves are formed by flexible, uniformly dense strings suspended from their endpoints and weighted under gravity.
Form Finding weighted string form-finding method Photos of the string forms are emulated to render interior and exterior building shapes by painting and tracing over the wire frame models of lines.
Sachets with lead shot resemble the weight of small building parts. The system of threads represents columns, arches, walls and vaults. An experiment for the structural innovations, like branching inclined columns and hyperbolic paraboloid surfaces.

when the anchor points are same, Length of the thread decides the depth of its curvature
with in the same anchor points, when the thread length increase the depth of curvature increases
The same thread displays difference in curvature when the orientation/ position of achor points vary
The mirror / inversion of these curves form arches
equal DISTANCE unequal THREAD LENGTH
unequal DISTANCE equal THREAD LENGTH
MODELING a catenary
and until unless acted upon external point forces, the catenary remains the same between a given same anchor point distance and length of thread
equal DISTANCE equal THREAD LENGTH

the Burke Brise Soleil is a moveable, wing-like sunscreen that rests on top of the Museum’s vaulted. Sensors on the fins continually monitor wind speed and direction.

26
developed surface of a cone by straight lines being revoled around a point
emanating straightlines from the same point to form cone in symmetry
when straight lines are generated from the opposite centre points
reiteration of the inverted double cone structure in both x and y axis to visualise the simluated lines as a new form
27
formed surface is defined by the density of lines points on the curves are joined in parallel direction
emanated ruled surface is combined with its mirrored self
more the density, the generation of surface seems more obvious
points on the curves are joined in opposite direction
several iterations are possible

VARIATION 3 CURVED FOLDING
folding along curved crease is not an easy task as it need attention to material tear / rupture, in this case poly proplene sheet
57
the form begin to crumble by every fold as concentric fold will face more strain than a normal fold with paper
proplene sheet has a tendency to revert back to its original state of being flat when left undisturbed for some while

these structures are designed granular objects whose form is a freestanding structure based on material property + profile an aggregate system consists of a loose arrangement of elements, where each part finds its own place and it is the task of the designer to observe and interact with the systems behaviour
DEFINITION
73
parametric investigation of possible construction geometries with loose granules is a breakthrough in construction technology the research focus is to make the particles behave as an alternative to building material property, it needs only the form work without any binder (one way is by temporary freezing with ice)
PRECEDENT ICD Stuttgart research
a material research project from Stuttgart, Germany examines designed aggregate / self-solidifying granulates that are fabricated by injection molding
