Cycling in Belgrade

The Woods (Belgrade)

Belgrade Forest is a mixed deciduous forest lying 15 kilometers north-west of Istanbul, Turkey. Geographically, the forest is located at the easternmost point of the çatalca Peninsula. Forest terrain is divided between Sarıyer and Eyüp districts. There are seven historical aqueducts which built in the different location. Those are kömürcü, büyük, ayvat, valide, kirazlı and sultan mahmut bendi.

Belgrade forest was the most important fresh water source for Istanbul, not only for ottoman period, but also byzantine empire period. Belgrade forest started to became important begining of the 16. Century. When 10. Ottoman sultan suleyman the magnificent had returned from belgrade compaign in 1521, he had brought a large number of serb prisoners and prisoners placed in the ayvat village which sited in the belgrade forest to diffuse turkish culture in this area. When belgrade based prisoners placed in the village came to be known as belgrade. In the sultan suleıman period, the task of repairing and building aqueducts, weirs and pools had given the architect sinan. atteiner aqueducts weirs and pools are a part of this period.

After the proclamation of republic in turkey, belgrade forest were protected. To take advantage from belgrade forest picnic areas are built around dams and the forest began to serve as reactional area in istanbul. Belgrade forest, still, a recreation area, clean water supply and continues to serve a coppice. 

When we entered the forest we asked the palce of the valide dam to the security and he directed us to the left(red) road. After we had been walking during 1.30 hours, we realized that there is not Valide dam. We went to Neşet Suyu because of security. Then we had hitchiked the entrance and walked again. Finally we found Valide Dam.

I think we were lucky, since the day we went is rainy. The sky covered with trees, like a giant dome. We can hear the sound of rain, perceive the smell of soil but we couldn't get wet, because of trees. 

In belgrade forest there are seven Dam and they are very close to each other. One of them is Valide Sultan(Queen Mother) dam. Valide Sultan dam was completed in 1796 which is located on the Acı Elma Creek. So it was built for mother of III.Selim mihrişah Sultan, it was named Valide dam. There is a picnic area and children play ground in the Valide dam. According to us children layground looks ugly, not related with the nature because of its material. It could be maden of wood or plastic which looks like wood.

Valide dam has slope and because of rain it was very sliding. Also one part of dam there are no parapet. The environs of the dam is surrunded by wire. Maybe the reason of the wire is the safety of people or protecting water against getting dirty is could be a main reason.

sketches,plans and sections for surface to walk on, vertical divider and solid... white hollow plastic tubes used in the models representing bamboo...

SURFACE

Developed Surface Model

2mm tubes were added to prevent collapse and bending when taking steps and bamboo strips used in one direction not like in the first model one is from top to bottom, other one is bottom to top. All bamboo strips pass through bottom to top.

SURFACE2

VERTICAL DIVIDER1

Developed Vertical Divider

The connection detail of tubes changed. They connect to 5-5mm square profile, then this square profile moves in the 8-8mm square profile easily.

VERTICAL DIVIDER2

Developed Vertical Divider

Bottom square profile is greater than the top profile, since support system.

Bamboo

Bamboos are grasses in family of Poaceae and grouped as a sub-family Bambosoideae. Bamboos are one of the fastest growing plants in the world. Their lenghts can reach up to the 15m, diameters changes between 5-12cm and diameter do not change through stem. Through stem there are some hallow and fulled parts; hallow parts are named as internodes, the fulled parts are called as nodal.  In the cross section of stem there are great number of vascular bundles which line in the vertical direction. Because of vascular bundles; they are highly elastic element, they have high tensile strenght even more than steel.

Bamboos are propagated with micropropagation methods also they propagates by seed but it is inefficient and old method. They harvested by cutoff saws at the end of rainy season and begining of the dry season. Dry season is the period of dormancy. Starch content is at its higghest level at the end of dry season. Harvesting bamboo at this season increases the chances of borer and fungi attacks. During rainy season, strach content is lower but moisture content in the bamboo culms is high, and it increases the splitting and cracking after harvest. 

BAMBOO IN ARCHITECTURE
They used generally Japaneese architecture. scaffoldings, houses, parquet, internal dividers, shading elements, bridges can be made from bamboo.

Bamboo flooring

Bamboo spilit into strips lenthwise. The cane is flattened and the curved walls are changed into flat strips. The bamboo Strips are placed in a lime kiln which they are dried at a low temperature. They are glued together with a methanol-based resin and compressed to form sheets which are cut into standarts lenght. The sheets are linked each other with a tongue-groove interlocking joinery system.


Connection Details

They can be glued, butted, nailed, bounded, tied with plastic rope, iron wire.
