    Performance enhancement of RC frames using welded wire fabrics - An experimental investigation
    (2010) Prashanth, M.H.; Chinnagiri Gowda, H.C.; Babu Narayan, K.S.; Ramana, K.V.
    The paper presents the performance enhancement of RC frames using welded wire fabrics to appraise beneficial effects of welded wire fabrics as lateral reinforcement in Reinforced Concrete elements. The RC frames subjected to lateral loading have been simulated to rhombus frame with vertical loading. The experimental investigation has been done on rhombus frame with vertical loading. Experimental program involved details of test specimens, test set-up and instrumentation. Comparison of conventional bare frames has been done for frame with welded wire fabrics as lateral reinforcement at discrete zone and frame with welded wire fabrics as lateral reinforcement throughout the length for the same volume fraction. Results of Experimental investigation have been reported from which the discussions and conclusions had been drawn. © 2010 Cafet-Innova Technical Society.

    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.

    Experimental investigation of RC frames using CFRP sheets
    (2013) Prashanth, M.H.; Babu Narayan, K.S.; Venkataramana, K.; Sajith, M.
    Reinforced Concrete frames are the main load resisting systems used in practice all over the world. These frames will be subjected to sway, due to lateral loading most of the times by either earthquake or wind. Ductility and energy dissipation capacity of the frame are the key parameters for better performance under the action of the sway loading. Retrofitting using the new generation material such as carbon fiber reinforced plastic sheets (CFRP) shows much enhancement in these properties of laterally loaded frames. Frames subjected to lateral loading introduce collapse mechanism due to the formation of the plastic hinges at critical hinge locations. An experimental investigation of partially and fully CFRP wrapped reinforced concrete (RC) frames when compared to conventional(bare) frame has been carried out, to bring out the importance of critical engineered locations to be wrapped. © 2013 CAFET-INNOVA TECHNICAL SOCIETY.
