    Experimental studies on Iron-ore tailing based interlocking paver blocks
    (2012) Ravi Kumar, C.M.; Anil, A.; Prashanth, M.H.; Venkat Reddy, D.
    Interlocking concrete block pavers (ICBP) has been extensively used in many of the countries due to concern with durability. They are utilized in a variety of commercial, municipal and industrial applications. The superior engineering properties, low maintenance, ease of placement and removal, aesthetic appeal and immediate availability are the primary reasons for choosing concrete block pavement over other paving surfaces. ICBP are colored using iron oxide pigments. The present investigation details the properties of ICBPs mixed with iron ore tailings as a partial replacement for cement. The paper discusses the experimental studies on strength characteristics and water absorption of iron ore tailings based concrete paver blocks by considering actual area and plan area and results has been compared with that of conventional concrete paver blocks. © 2012 Cafet-innova technical society. © 2012 Cafet-Innova Technical Society.

    A parametric study on seismic fragility analysis of RC buildings
    (Techno Press technop2@chollian.net, 2016) Nagashree, B.K.; Ravi Kumar, C.M.; Venkat Reddy, D.
    Among all the natural disasters, earthquakes are the most destructive calamities since they cause a plenty of injuries and economic losses leaving behind a series of signs of panic. The present study highlights the moment-curvature relationships for the structural elements such as beam and column elements and Non-Linear Static Pushover Analysis of RC frame structures since it is a very simplified procedure of non-linear static analysis. The highly popular model namely Mander's model and Kent and Park model are considered and then, seismic risk evaluation of RC building has been conducted using SAP 2000 version 17 treating uncertainty in strength as a parameter. From the obtained capacity and demand curves, the performance level of the structure has been defined. The seismic fragility curves were developed for the variations in the material strength and damage state threshold are calculated. Also the comparison of experimental and analytical results has been conducted. © 2016 Techno-Press, Ltd.
