Seismic performance of irregular buildings A. Sujatha Indian Journal of Science and Technology, 2014 Modern building planning is influenced by many factors and often, there is a trend to adopt a form that has irregular shape in plan and also has variation in height of storeys. Due to the varied use, a building is planned for; variations in the load acting on different floors may also differ. More irregularities can be present like non continuation of members in all the floors, or absence of members, and also having additional members in some of the storey levels. Such buildings will have maximum risk, when compared to conventional framed structures, when seismic forces come into play. This paper highlights the various aspects in the performance of buildings, and also suggests some remedies for the problems. Keywords: Building Planning, Irregular Buildings, Seismic Performance
Prevention of fire in tall buildings A. Sujatha Indian Journal of Science and Technology, 2014 Fire outbreak in a building will, obviously, create panic and confusion in people occupying it. Fire causes slight to full damage to properties, persons and also in worst cases, leads to collapse of structures. If the fire intensity is more, there are chances that it may affect the neighbouring structures. Fire resistance of different building materials will not be the same, and their behavior during fire will be a major issue, once fire outbreaks. This paper highlights some of the aspects of fire safety in a building, and also some of the precautions we can take during such fires. Keywords: Buildings, Fire Safety, Fire Control
Geodesic domes and its applications A. Sujatha Indian Journal of Science and Technology, 2014 A man made structure becomes stronger as its size is increased. They find application in the roofing of buildings. Geodesic spheres are arrangements of polygons in great circles that approximate a true sphere. Of all structures built from linear elements, a Geodesic Dome has the highest ratio of enclosed volume to weight. This paper highlights the uses and applications of geodesic domes along with their geometrical properties. Keywords: Curved Lattice Grid Dome, Geodesic Domes
Case study report on distress in water tanks A. Sujatha Indian Journal of Science and Technology, 2014 Over head water tanks, made up of reinforced concrete are more common due to the fact that it can be easily cast in any desired shape and size. The durability of such tanks may get affected due to external agents like wind, air etc. and needs maintenance periodically. The corrosion of reinforcement is the major distress of any reinforced concrete structure, and these tanks also face the same problem. Once the corrosion of steel happens, the satisfactory performance of the reinforced concrete tanks gets affected and distress starts in the form of minor cracks. If left unchecked, the effects of corrosion may propagate further and may lead to structural failure in due course. In this case study, many overhead tanks made up of reinforced concrete were studied, and their types of distress along with remedial measures are suggested.
