  Achyut P. Kanvinde (1916 –2002), the Indian architect with functionalist approaches with elements of Brutalist architecture. He was born in Achra, in Konkan region of Maharashtra in 1916. He believed that a grid of columns forming a matrix giving structural and spatial aspect would turn a design more sophisticated and faceted. ·        1935: Studied architecture under Claude Batley in Sir J. J School of Arts ·        1945: Completed Masters from Harvard, student of Walter Gropius (Thesis on Science Laboratories) ·        1947: Chief Architect of CSIR (Council of Scientific and Industrial Research) ·        1955: Formed Kanvinde and Rai LIFETIME ACHIEVEMENTS ·         1976: Received the Padma Shree ·         1974-75: Became the president of IIA (Indian Institute of Architects)...

Bamboo - Building Construction Material

-


 Since time immemorial, bamboo has played an important in the development of mankind. Bamboo is a natural composite material with a high strength-to-weight ratio, which is generally similar to strong softwood or hardwood. They are the fastest-growing plants, certain species growing up to 35 inches in 24 hours.

HISTORIC USE

The regions traditionally associated with the use of bamboo as a building material are South and East Asia, South Pacific and Central and South America. In China and India, bamboo was used to holding up simple suspension bridges by making cables of split bamboo or twisting whole culms of bamboo together. In Japanese architecture, it was used as supplemental and/or decorative elements like fencing, fountains, grates and gutters. To date, most high profile bamboo construction projects are in Vietnam, Bali, China and Columbia.

BAMBOO HOUSING

·       FOUNDATIONS

1.      Bamboo in-direct ground contact

2.      Bamboo on rock or perforated concrete footings

3.      Bamboo incorporated into concrete footings

4.      Composite bamboo/ concrete columns

5.     Bamboo piles

·       FLOORING

1.     Small bamboo culms

2.     Split bamboo

3.     Flattened bamboo

4.     Bamboo mats

5.     Bamboo plastic composites




·       WALLS - The different varieties are as follows:








  • ROOFING - There are different types of joineries used in roofing techniques using bamboo.




 





·       

·       SCAFFOLDING - Due to the favourable relationship between load-bearing capacity and weight, bamboo is used as scaffolds in the buildings.

RESISTANCE TO EARTHQUAKES

·       Due to the high residual strength of bamboo to absorb shocks and impacts and the flexure coupled with its very low mass, bamboo is resistant to earthquakes.

·       A bamboo house withstood an earthquake that occurred at Sikkim measured 6.9 in September 2011.

·       30 houses at the epicentre of a 7.6 magnitude earthquake survived without any damage in Costa Rica in 1991.

ADVANTAGES OF BAMBOO AS A CONSTRUCTION MATERIAL

·       Strength – Bamboo is an extremely strong natural fibre, when cultivated, harvested and stored properly.

·       Flexibility – Bamboo is highly flexible and can be bent and used in arches and other curved structures.

·       Earthquake resistance – It has a great capacity for shock absorption, which makes it particularly useful in earthquake-prone areas.

·       Lightweight – As bamboo is lightweight, construction with it requires simple tools and is accomplished faster.

·       Cost-effective – It is economical, especially where it is cultivated and the transportation cost is also less.

·       Durability – It is long-lasting when harvested and maintained properly.

LIMITATIONS

·       Joining techniques – A number of traditional joineries exist, but their structural efficiency is low, thus considerable research is being done for the development of more effective methods.

·       Flammability – it is not fire-resistant, and the cost of treatment is quite high.

 

Bamboo has been the backbone of much of the world’s rural life and will remain so as the population increases. Due to the increase in interest towards bamboo as a building material, many architects and builders like Simon Velez, Marcelo Villegas, Oscar Hidalgo – Lopez, John Hardy etc. The high-value utilization of bamboo will not only promote economic development but also saves forest resources to protect our ecological environment as a wood substitute.

Mass Timber

  In recent times, there is widespread enthusiasm for mass timber in building construction. But why use mass timber? To get the answer to this question, let us know the importance of timber in construction. As we all know, timber is the only renewable construction material but very fewer people will know how powerful the CO 2 sequestration of trees is, i.e., in a metre cube of timber building material, approximately a tonne of carbon is stored within the building. So, now we know that we should increase the amount of timber used in buildings. To do so, engineered mass timber products can be used instead of a typical timber frame. WHAT IS MASS TIMBER? Mass timber is a category of framing styles which use large solid wood panels for walls, floors and roof construction. It is available in innovative forms of sculpture building and non-building structures formed from the solid wood panel or framing systems. Due to its strength, dimensional stability and being a lo...

Louvre Pyramid - The Introduction for Modern French Architecture

-
Image
Louvre Pyramid completed in1989, designed by I. M. Pei, is a large glass and metal pyramid in the main courtyard of Louvre Palace (Palais du Louvre) in Paris, France. The large pyramid serves as the main entrance to the Louvre Museum and is surrounded by three smaller pyramids. Amid the controversies that surrounded the structure, Louvre Pyramid stands in front of the world’s most visited museum and despite its relative youth, it has become a vital part of Paris’ renowned skyline. The structure is entirely made up of glass segments and metal poles, and has a height of 21.6 meters (71 feet) and a base surface area of 1000 square meters (11,000 square feet). It has a total of 603 rhombus-shaped and 70 triangle-shaped glass segments, which was an effort to make the pyramid as transparent as possible. The main reason the Pyramid and the underground lobbies were created was the series of problems with Louvre’s original main entrance which could no longer handle the ...

Art Deco

Style Moderne, popular as the “Art Deco” movement was based on visual arts, architecture and  design, first appeared in France just before World War I. This movement influenced the buildings, furniture, jewellery, fashion, cars, movies theatres, trains and everyday objects. Art Deco was a blend of modern styles, fine craftsmanship and rich materials which represented luxury, glamour and exuberant faith in social and technological progress. Rich colours, bold geometric shapes and lavish ornamentation marked the style. The rise of new materials and technologies gave way for this style, especially reinforced concrete. With the discovery of the use of a mesh of iron rods in concrete to strengthen it and use it to build various buildings, Art Deco started to flourish as it was easier to make different forms with concrete. ART DECO TIMELINE ·        1920s- The style was first applied to public and commercial buildings. It was rarely used to designed ...
