It all started in spring of 2004 in Dharwad, with Namaskarams to Shri Dharmasthala Manjunatheshwara and blessings of Lord Shree Ram, parents Lecturers and Professors of SDM College and SDMCET Management. Civil engineering was that link I could connect to the creation. Creation has so many aspects like temporary or permanent, luxurious or economic , sturdy or lean, Safe and only safe. Our perspective of civil engineering should be safety such that nothing in the structure should not behave in unintended manner during the life span of structure.
quadrilateral, expressways ,etc lead to infrastructure development was a time when demand for civil engineering was gradually growing.
Before joining civil engineering, whenever I used to see bare walls I always used to wonder why the bricks are staggered and not placed one over the other, Why when we put water on sand its volume increases, Why do we sieve the sand while making concrete, why bricks are soaked before constructing wall, Why buildings made from stone like brihadeshwara temple stand tall thousands of years but our buildings life is only 100 years.
Let me answer these questions the bricks are placed in staggered manner because if the bricks are placed linearly one over other the failure plane will occur and the wall will fail along the joint so inorder to break the continuity and make the wall stable and increase its strength the bricks are staggered and there are many types of bonds like English, Flemish etc used to construct wall. The sand volume increases with increase in water this phenomenon is called bulking after a specific water content the volume decreases. Bricks are soaked in water so as to when mortar is applied to brick while constructing wall it does not absorb water. And yes durability of buildings is important aspect the steel we use in buildings corrode over time and hence it is difficult to take buildings upto 100 years where as The lofty temples which are constructed from stone are very very durable.
