Abstract: With the rapid industrial growth globally, steel industries, in particular, are producing huge quantity of slag as by-product in different forms obtained through various cooling processes. These by-products are environmentally hazardous, create problems of storage, thereby reducing effective land-use affecting economy of the country. That is why, proper utilization of such waste materials and its management has become one of the most complex and challenging tasks over a period of time. Present study basically aims at investigating the scope of use of such a by-product Granulated Blast Furnace Slag (GBFS) as fine aggregate replacing natural sand partially or fully in concrete structures, in order to reduce environmental problems and waste disposal, also in terms of preserving natural resources. In this experimental investigation, design mix of various grades are prepared with various percentages of replacement of natural sand by GBFS. Based on the test results and detail investigation o

BASE ISOLATION FOR ARCHITECTURAL TEMPLES

Abstract: The paper addresses earthquake protection for architectural masonry temples of India, which are supported over large marble pedestal. The concept of seismic isolation has been applied here to these temples by separating the super structure from the pedestal by a smooth friction layer in the form of marble/marble interface. The response of the base isolation system is estimated numerically by solving the governing equations of motion under earthquakes ground motion compatible with the 5% damping design spectrum of Indian standard code for earthquake resistant design corresponding to the level of maximum considered earthquake in the most vulnerable seismic zone. In comparison with the response of the fixed base structure, nearly 50% reduction in absolute response acceleration for the isolated temple building was observed at the roof level at the cost of 30 mm base sliding displacement, which is well within large marble pedestal and can be used as a base isolation technique for preserving
