‘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.

Intricacies of this age-old construction 6. First the wooden construction was erected before filling up the intervening voids with dressed stones. Siting of these kkoti is another important aspect for their safety against earthquakes. It is observed that many old structures in the Koti 8. References Himalayan Seismic Hazard R.

Koti Banal architecture: How ingenuity of our ancestors conquered earthquakes

Vertical load-bearing elements columns, walls are attached to the foundations; concrete columns and walls are doweled into the foundation. The concept of modern architecture and engineering is not prevalent in the region, even today. At the time of construction, the builder definitely belong to the rich social class. Thus allowing pure lateral deflection during dynamic shaking while avoiding torsional effects. Koti Banal is the name of a village in the Abnal Valley which represents the traditional knowledge and understanding of earthquake effects on architecturd and their earthquake resistant design.

Locally and then abun- the fine-tuning of resource management practices, as also dantly available wood was judiciously used in these life-support strategies, so as to protect the interests of the structures.


Koti Banal

This architecture might well have started after the p. The mission is to share experiences with different construction types and encourage the use of earthquake-resistant technologies worldwide. Zrchitecture of practice for design loads for buildings and structures Bureau of Indian Standards.

Both the local and Assam earthquake, apart from Kumaun earth- dialects of the region Kumaoni and Garhwali have quake of and Garhwal earthquake baanl Our ancestors, having lived so close to the nature, observed the earthquakes and realized ways to minimize the destruction caused.

Great Himalayan earthquakes and the Tibetan plateau N. The World Housing Encyclopedia WHE is a collection of resources related to housing construction practices in the seismically active areas of the world. The ingenuity of our ancestors lies in the fact that they used wood to create the frame of the structures. Log In Sign Up.

The Koti the wood samples collected from the panels used in the Banal structures fall under the high-rise wooden building buildings was analysed and calibrated at the Birbal Sahni Institute of Palaeobotany, Lucknow.

Wood being both strong and lightweight, ground acce- utilizes a number of wooden assemblies that help lerations are unable to generate as much energy archutecture wood in resisting earthquake forces that are a function of buildings as in the ones constructed with other materials.

Damage patterns observed in past earthquakes for this construction type. More and more people are trying to emulate the pretentious city lifestyle — in the hills. The majority of existing buildings had been observed in the region.


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 be seen identified as chaukhat, four-storied or pancha- with stones, which is similar to modern-day framed con- pura, five-storied. Figure 8 exemplarily shows the elevation of a five story structure with interstory heights ranging between 2. These age-old structures must have struction.

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. Locally and then abundantly available building material wood and stone was judiciously used in these structures and the structural designing of the structures suggests that the ones responsible for designing these buildings had fairly good idea of the forces likely to act upon the structure during an earthquake.

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. The Gona type may well represent earlier stages of the evolution of the Koti Banal architecture.

Earthquakes in India and the Himalaya: The height of these structures varies between 7 and 12 m above the base platform which consists of dry stones. Obviously the erection of these structures had been a archiyecture effort.
