‘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.

About The World Housing Encyclopedia WHE is a collection of resources related to housing construction practices in the seismically active areas of the world. The kitchen is generally on the top floor. Enter the email address you signed up with and we’ll email you a reset link.
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. Magnitude calibration of North Indian earthquakes N. Building Materials and Construction Process. For buildings of the Koti Banal arcbitecture, locally available building materials such as long thick wooden logs, stones and slates were judiciously used.
A structured The multistoried traditional structures are constructed questionnaire was utilized for assessing the perception of on raised and elaborate stone-filled solid platform which the masses towards structural safety-related aspects, as is the continuation of the filled-in foundation trench also their tradition.
Accounting for the wall fillings out of dressed architecturee and the additional masses a reduction of the vulnerability class into C D may be suitable.
If the is coordinated.
Koti Banal architecture: How ingenuity of our ancestors conquered earthquakes
The roof diaphragm is considered to be rigid and it is agchitecture that the roof structure will maintain its integrity, i. Foundation trench filled with rubble and field stones. Log In Sign Up. This kind of joint incorporates ad- vantages of both pin joint architectuure rigid joint and acts as a semi-rigid joint, which is an additional advan- tage for shock resistance. The thickness of the walls is determined by the thickness of the two parallel arranged wooden logs which is mostly between 50 and 60 cm.
Koti Banal – Parikrama
This arrangement divides the structure into four parts Figure 2. These buildings which are up to five storeys tall have survived the overturning effects even agchitecture strong earthquakes due to two reasons: Who performed the construction: That seems to be the case in the Rajgarhi area of Uttarkashi district in Uttarakhand where centuries-old unique architectures have amazed researchers from country and abroad.
The present structure has are made of 20—22 mm thick wooden planks that are ex- been constructed on rocky and hard soil for which, ac- pected to exhibit high degree of flexibility, while all the cording to Clause 6. The other two walls are raised with well-dressed flat stones to the level of the logs placed on the other two sides. These age old structures must have witnessed many earthquakes.
The seismic design handbook R. For example, if the government are planning to have a hospital or clinic or dispensary built somewhere in the hills, instead of building a generic cemented structure, why not build it using Koti Banal technique?
In most cases, Koti Banal structures were erected separately without any buildings in the immediate vicinity. Housed and nailed joints used for fixing the wooden com- and concrete.
For contemporary constructions in the region, no such logs ring beams are used anymore. The description is prepared from a number of standard closed-ended questions and some narrative that have been provided by report authors. Externally arranged verandas made of timber and resting on massive columns have also been added in order to gain additional living space Figure As the wave of modernity sweeps over Uttarakhand, the cement-based construction is gaining popularity even though it is not suited to the climatic conditions of the region.
It exhibits elaborate procedures for site selec- earthquake1. Finite element method would be the most would have experienced at least design basis earthquake suited modelling method for such complex masonry— DBE 9 ground-shaking in their lifespan. Generally the buildings rest upon a raised and elaborated stone-filled platform out of dry stone masonry which is the continuation of the foundation trench made of field and rubble stones.
This architectural style of these houses demonstrates the existence of elaborate construction procedures based on principles somewhat akin to that of blockhouse construction. The use of horizontal wooden logs in the vertical walls is similar to the concept of seismic bends ring beams in modern masonry buildings. Using the ancient technique with modern technology is the way forward, in my opinion. The ratio of width to height of these and the soil may produce long-period motion.
The building system thus meets the required space rigidity as also strength requirements.
The Koti Ba- derstanding led to the evolution of innovative practices nal architecture, however, did not cater to the comfort for minimizing human losses emanating from structural of the inhabitants.
