‘Koti Banal’ architecture of Uttarakhand is a reflection of indigenous realities and community involvement. It demonstrates a profound. This construction style, designated Koti Banal architecture, attained its zenith around years ago. This architectural style exhibits the existence of elaborate . It is reported that especially buildings of the Koti Banal architecture withstood and performed well during many past damaging earthquakes in.

The ratio between both dimensions varies between 1. This was architectkre responsible for collapse. Help Center Find new research papers in: The walls are raised by placing double wooden logs horizontally on the edge of the two parallel sides of the platform.

The banl seismic base shear ily have a continuous load path. Uttarakhand is located in the seismic gap of storied klti houses with marked baanal and the Bihar—Nepal earthquake and Kangra earth- distinct construction style. Seismic performance of these structures has been tested by the Kumaun earthquake of and Garhwal earthquake ofthat are considered to be highly dam- aging.

For more information about the World Housing Encyclopedia, visit http: Koti Banal architectural style exhibits existence of elaborate procedure for site selection, preparing the platform for raising the multistoried structure, as also for the detailing of the entire structure that was constructed on principles somewhat akin to that of framed structures of modern times.

Tri-directional seismic analysis of an unreinforced masonry building with flexible diaphragms S. These buildings which are up to five storeys tall have survived the overturning effects even of strong earthquakes due to two reasons: The wooden frame of the entire structure was region four to five-storied traditional structures can still finalized first and then the intervening voids were filled architecrure seen identified as chaukhat, four-storied or pancha- with stones, which is similar to modern-day framed con- pura, five-storied.

Remember me on this computer.

Especially those located in the villages may also be built close to each other or to other building types Figure 3 When separated from adjacent buildings, the typical distance from a neighboring building is 2. The general load path for VB is calculated to be the multiplicative product of hori- the Koti Banal structure is as follows: The significant features of practices for ensuring survival against all odds.


Known as Koti Banal in local parlance, large number of these multi-storied traditional houses exhibit antiquity and distinct construction style. However, this may only be kofi for the lower part where the stones were only used to fill up the voids.

Koti Banal – Parikrama

Regions unique words for identifying four different floors of a between the rupture zones of the great earthquakes are building. For the two bottommost layers single wooden logs while for the upper layers double wooden logs are used Figure 9.

Was the construction inspected in the same manner as new construction? Recently, many Koti Banal structures face serious adverse effects being caused by the surrounding building development. As an added advantage, wood-frame systems flex more vi Wood-frame construction, structural walls and than other materials, thus absorbing and dissipating floors sheathed with structural wood panels emplo- energy.

Externally arranged verandas made of timber and resting on massive columns have also been added in order to gain additional living space Figure You are commenting using your Twitter account. Investigations suggest that the region had evolved this elaborate and magnificent earthquake-safe construction style as early as 1, years before present. The thickness of the walls is determined by the width of the logs 70 cm. Both the local and Assam earthquake, apart from Kumaun earth- dialects of the region Kumaoni and Garhwali have quake of and Garhwal earthquake of This has resulted in a mixed structure with two witnessed many earthquakes and in the absence of the types of load-sharing mechanisms: Buildings of this type are generally well maintained and there are no visible signs of deterioration of building elements concrete, steel, timber.

Categories of wooden buildings and their design methodologies tistoried structure at Guna, though built using similar archi- tectural style, is more occupant-friendly with the roofs Seismic design type of building Seismic Seismic design being sufficiently high.


Investigations suggest that the region had architecturw this elaborate and magnificent earthquake-safe construction style as early as 1, years before present.

The most magnificent examples of the Koti Banal architecture are observed in the valley of the river Yamuna in Rajgarhi area where many villages have a fair number of these houses.

In situ testing is also required for assessing the having experienced many earthquakes in the past Figure strength architecturre the stone walls as also wood employed for 7. Molnar Science Number of inhabitants in rachitecture typical building of this construction type during the day.

Normally one family occupies one building. Koti Banal structures in general have a single small entry and relatively small openings which are surrounded by strong wooden elements to compensate for the loss of strength Figure Notes on vulnerability rating: While these uniquely constructed structures have gained the attention of archaeologists, seismologists and mechanical engineers for their remarkable ingenuity, the neglect from the people and administration have led to the wear and tear of these architectural marvels.

Generally the buildings have a single room on every floor with a vertically distributed usage. The Koti Banal architecture is a mixed construction of timber and dressed stones which are according to EMS denoted as simple stones. The balconies are supported by cantilevering wooden logs of the flooring system Figure 6. According to Middlemiss it is this projecting balcony which gives the house the false appearance of being top-heavy and unstable.

Similarity in ticularly tall structure during seismic loading.

It is reported baanal especially buildings of the Koti Banal architecture withstood and performed well during many past damaging earthquakes in the region. The walls parallel to the floor beams are supported in out-of plane action by providing a large timber log, longer than the building dimension and having holes at the two ends.

On the the north of Barkot across Yamuna Figure 1for esta- two sides of the structure, wooden beams are provided blishing elements of earthquake safety in these traditional from the outside. These seismogenic forces are sudden, dynamic and can Wi hi2 architectuure of immense intensity.
