Mangaluru, May 25, 2016: A Project exhibition of Ogival Shell structure constructed at Dakshina Kannada Nirmithi Kendra by Tariq Aziz, MTech (Structural Engineering) student of Srinivas School of Engineering Mukka was inaugurated by Mangaluru North MLA Mohiuddin Bava.

The eco-friendly and low-cost bud-shaped pointed shell structure was constructed without using steel and concrete which can withstand all types of climatic conditions was executed under the advice of Dr K S Jagadish, Professor Emeritus, IISc Bengaluru and under the guidance of Prof Subramanya Bhat P of SSE, Mukka.

Aziz said the shell structure has a perimeter of 30 foot. It is nine foot tall and is constructed by using four-inch thick brick wall. The structure did not deform even after applying a load of 2,000 kg, he added.

He also said that by adopting this construction technique, around 30-40 per cent basic construction materials can be saved which in turn help in conservation of energy. This type of structure can be constructed at religious places, tourism projects, resorts, rehabilitation and housing projects. Steering and tilting rod technology was developed and incorporated in this project which can rotate 360 degrees to maintain same radius at different levels which helps in maintaining bud-shaped pointed shell and also ease in construction. Construction of "bud" shape using concrete is a tedious job, since it includes sloping formwork and curved reinforcements. Hence, the masonry construction of this nature can be a good alternate to RCC which bears good strength and also act as thermal insulator, he added.

Bava said this project is proved to be a green construction as a lower quantity of cement is used and no steel and concrete.  Nirmithi Kendra Project Director Rajendra Kalb was present.
