Joglo earthquake-resistant houses

Struktur Rumah Joglo

Building Joglo interpretation raises Java architecture that reflects serenity.
NOT just a magnificent, beautiful, full of meaning and socio-cultural values​​, architecture can also reduce earthquake joglo. A building joglo pose interpretation reflects the tranquility of Javanese architecture, present among the buildings that diverse. This interpretation is characterized by the use of a solid roof construction and the arch-arch shape in space per room.

Joglo is the main building frame of traditional house consisting of a pillar of the main pole with a sleigh four overlapping Songo (nine overlapping) or overlapping telu (three overlapping) on it. Joglo structure like that, except as the support of the main structure of the house, as well as the pedestal roof to roof to form pencu.
In house building architecture joglo, the art of architecture is not just understanding the art of home construction, is also a reflection of values ​​and norms of the community supporters. At the entrance has three doors, the main door in the middle and the second door is located on the left and right side of the main door. The third part of the door has a symbolic meaning that the bow fighting in the middle for a big family, while two doors on the right side and left to-laws.

In the space inside is called Gedongan serve as a sanctuary, where the imam leads the prayer that is associated with symbolic significance as a sacred place, sacred, and sacred. Gedongan also doubles as a bed and a respected principal at certain times be used as a bedroom bride.
Traditional buildings such as houses joglo that many use natural elements in it, proved resistant to natural disasters such as earthquakes. Many factors cause joglo earthquake response. Deliberately used the word rather seismic quake response because this building seems to be able to respond and engage in dialogue with the force of the earthquake.
First, the system structure used. People think joglo structured framework because it does look the logs are arranged to form the framework. Structure joglo implement a tent or pull system. It is based on the system and the connection properties of wood used (cathokan and birds), it is anticipated gravity.

"Building joglo can dampen earthquake because it has a linkage between the structure and materials, joints between rigid timber that is not so flexible and have a high tolerance to earthquakes," says architect and contractor of Mitra Mandiri Graha Asri Ir Wisnu Brata. Second, the system load distribution.
The building has a cornerstone joglo (mast) 4 pieces and 12 pieces pengarak pillar. The space created by the so-called fourth pillar of the drive aisle, which is the core structure joglo. Soko-pillar united by beams (beam-sledge and sunduk-reel) and collected by arrangement kakukan-shaped wooden staircase punden upside down on the edge (intercropping) and the shape of a pyramid in the middle (brunjung).
The composition of this wood are flops and creates a very rigid stiffness. Soko-pillar pengarak in fairies is seen as supporting the core structure. The third factor is the support system and connection systems. Joglo pedestal system building using joints that are extolled. This is to compensate for the behavior of structures that are flops. Connection system which does not use nails, but use the tongue groove system, allowing tolerance to the forces acting on the logs. "Tolerance is causing friction so that the building can accommodate accept earthquake forces.
The selection and use of building materials is the fourth factor. The use of wood for the walls (gebyok) and clay tile roofing materials due to this relatively mild so not to overburden the building.
