I’m a computational designer. My main interest is Parametric Design and subjects such as parametric modeling of Islamic Patterns, Structural studies on parametric forms and also Automation in construction. I have tutored Grasshopper and Parametric Design for more than 300 architectural students including Architectural firms in Iran (ReNa , Diba, Fluid Motion) and famous Universities ( Tehran Uni, Shahid Beheshti, Elmosanat, Pars and Tabriz Uni) since 2010.

The construction of Space Frame Structures with Bamboo Using Innovative Pin Joint Connections

The structure as the main building block of buildings should in addition to the bearing of its own weight, be able to resist against forces caused by non-structural elements and external loads, and this tolerance has a key role in the construction of buildings. For the construction of building structures, various materials could be used, and among them, we prefer to use materials which have a higher resistance factor and lower weight. The bamboo shoot could be used as a convenient alternative for load-bearing elements of buildings since it is highly resistant and light along with being compatible with the environment. Due to the specific mechanical behavior of bamboo which its greatest resistance is in compression and tension, it is one of the most appropriate structural systems that could be used for systems which have a linear behavior, for instance, two-dimensional trusses and space frames. But it should be noted that the usage of bamboo in structural system of space frames could cause problems due to low shear resistance in designing member’s connections to the node. In this study, by designing a novel joint connection using galvanized plate and clamp, the weakness of bamboo against shearing forces are eliminated and also the implementation of space frames are facilitated.

Study of Soh’s Shale Soil for use in Lightweight Building Materials

It all started with heating the soil up to 1300 degrees
The first sample had more iron
Then we combined the clay with bentonite!
We tested the results based on different combinations
Our cake is ready!!
We found the best mixture of the clay and bentonite for maximum expanding
Preliminary Study of Parametric Cantilevers based on Dandelion and Goat’s Beard seeds

Plants are a group similar to buildings which use several techniques to maintain their stability. Their seeds are a specific part designed for reproduction with various methods associated with them. Some seeds are protected by shells and some are lightweight to allow the seed to move in the air easily. Dandelions and Goat’s Beards are two examples of plants using the lightweight technique to spread their seeds. The parachute-like attachment of their seeds is designed to lift easily by the wind. These attachments have a unique structure which resembles a structural lightweight shade. The parachute-like structure is made up of thin strands projecting from several radial horny stems. These stems are upward cantilever structures which their natural form will increase upward drift when the wind load is applied at the end of the stems while reversing the load’s direction gives a cantilever with a minimum vertical displacement under downward point load. In addition, the radial stems are prestressed by the strands. This research studies the structural behavior of parametric cantilevers arranged radially. The cantilever is defined by control points and the effect of moving the control point on the structural behavior of the cantilever is studied. Attached structures of Dandelion and Goat’s beard seeds and presents a lightweight system which imitates the techniques used in nature to produce pre-optimized lightweight structures.

First I  defined two parameters for the cantilever
Then I studied the displacement of the cantilever based on different parameters
Then I assigned a force at the end of the cantilever and studied it again!


A Preliminary Study of the Structure and Architecture of Walnut Shell
Shell-type structures can be found almost everywhere especially in natural forms with examples that include eggshells, turtle shells, nuts, animal skulls, tiny living cells, seashells, and crustaceans. Nuts are good examples of nature covering the central part of the fruit with a dome-shaped shell, which is resistant against compression. The shell design of a walnut seems to be designed to resist fracture by external forces. Nature, through adaptivity in the form of natural selection, has improved structural attributes. In this preliminary study, the walnut shell was studied under different loads to derive the optimized loading behavior of the shell. This new data on the behavior of walnut shell under different loading conditions besides theoretical examples proposes walnut shell as an appropriate choice for further studies on designing an optimized shell under point load or cylindrical shells with interior partitions under dynamic loads. Further studies by the use of pre-optimized walnut shell structure in connection with construction software and FE programs will save time and money and offers more flexibility to designers and product engineers in the shell and spatial structure designing field.
First I defined the parametric shell 
Then I studied the different shells based on maximum displacement
 Then I optimized the parametric walnut shell
