Today in arch 241 course Gökhan Ongun was our guest for modelling and 3D design workshop. The workshop included Rhino and Grashopper programming and basics of 3D modelling. Here are some shots from the workshop.



Erimtan Archeology Museum, Site Visit

Posted on Updated on

Last week, we made a visit to Erimtan Archeology Museum (by the artchitects Onur YÜNCÜ, Ayşen SAVAŞ  and Can AKER) placed to the highest part of Ulus, next to the Ankara Castle and near  to the Rahmi Koç Museum. I am emphasizing the area this much, because it has valuable details of old Ankara, which includes all those stone buildings and stylish treatments to the facade. To mention, the contextual details and such harmonical parts are -as you see at the figüre below- still preserved also by the architects of the building. As a structural detailing, it is still in construction which gives us a chance to see the architectural and structural details of it. Before starting to detailing the structure, I want to Show you a picture from the Site promotion board, which would make the explanations and generic expression of the building, more clear.

Here the whole facade of the designed structure. It is actually placed instead of three houses built there before, but as you can see they are still there which is a really nice approach in my opinion. As you see it has contextually harmonic walls which are not -for the outsider part- carrying the structure but carrying their own. This is as our instructor, and also one of  the architects of the building, Onur YÜNCÜ told, is one of the “tricky” parts of the building. Because they prefered to preserve the contextual  values, but they also wanted to have a higher building and wider interior space, which is not possible by using stone walls as bearing walls. So, as a solution, they designed a structure which has it’s bearing details “hidden” from surface to interior, and also has it’s contextual harmony. Here is a Picture which on the left shows the actual museum building, and then the building next to it, to see the harmonical preservation of the context in a better manner.

Now let’s get more detail about the structural planning of the building. As I mentioned before, those stone wearings are not carrying the structural parts. they are only the contextual dresses of the building, which are carried by the insider structure and mainly carried by the concrete walls we see at the parts below. Those concrete walls are actually the load bearing walls for the whole structure’s loads. Sometimes they had openings so they made the windows’ upper parts acting like beams. As an interesting point, we do not have any load bearings such as columns or walls visible. Because the architects also wanted to have a space which has not got any distributions for interior wide space. so, they prefered to transfer the live loads to the structure’s main scheleton as they did for the structure’s own loads. Also as a design detail they emphasize the ground level defined there before, also while providing the architects to have a higher structure by defining the levels from underground. For the rain gutterings, there is also again a really nice approaches of having them as partitional separators. we still see the boundaries of old houses, because the gutterings are placed according to this aspect. also the Stones used for covering the structure are gathered from those old three houses so that we have all those window details preserved and this much visible harmony.

Also as another detail, the designers applied a really nice thing to the windows. I can hear you asking what kind of a trick we have again! The building has windows whicch are placed and applied by a burrying technique into walls, which is for emphasizing the placement next to Ankara Castle. Because we have a context which is clear on having such references to the castle, so the architects thought that: why not to emphasize? Here is a Picture from outer side and also from inside which examples the light game.

As another detail from the main structure, here is a Picture from the roof structure which carries it’s own and designed in a manner which provides the widest space. In order to have such a space there, we have the stretch connections for possible changes in connection angle.

Now I want to share a detail Picture from column and beam hinge from the insider part of the structure, but showing the thing that how the architects of the building applied the solution to the main structure. As you see in the Picture too, we have the gap left there for the stone facade, and the actual structure behind this clothing. Also in a wider scale, other Picture showing the part which has not got this application but has the actual scheleton yet.

TENSEGRITY MODEL MAKING – Structure and Statics Exercise

Posted on

As you know, actualy this is an explanation for the ones who is facing with “tensegrity” issue for the first time, tensegrity is the situation which has a stability provided by only compression and tension forces. Also in addition, the elements of the structure are not allowed to touch each other. Here is the link to have a more  clear definition of tensegrity issue in mind:

now, here is the gallery for the model with 6 sticks (2 units length for each), 6 rubber threads (1 unit length for each).
