Studies on combined bending and torsion of ultra high performance concrete beams

Abstract

Recent boom in construction sector plays a vital role in nation s newlineeconomy, which is evident in the various developments in the sectors, which newlineincludes residential buildings, work places, organizations and so on. In newlineaddition to that, globalization results in the introduction of new connectivity newlineincluding construction of roads, bridges, ports, railroads, tunnels etc. With newlinethis keen importance along with financial advantage, more researches focused newlineon the construction sector with various perspectives to draw optimized newlinesolution suitable current needs. On the other hand, contemporary newlineadvancements in concrete technology force the introduction of new materials newlineincluding fibres, additives, super plasticizers and so on, which led to the newlinedevelopment of many new optimized concrete. Among which Ultra High newlinePerformance Concrete (UHPC) stood in front due to its greater mechanical newlineand durability factors. There are many evidences to prove these facts in the newlinestate of art, but still there is enough room in the combination of steel newlinestructures and concrete composites with UHPC. On the other hand, concrete newlinecomposites along with steel fibres gained popularity in current research realm, newlinewhich is evident in combination of two or more dissimilar materials under one newlinefunction as concrete. Combination of materials are not solely responsible for newlinethe element bulk properties, instead proper reinforcement increased the whole newlineperformance. Hence, some studies explore the concrete with shear connectors, newlinewhich are used to improve the strength of the proposed concrete mix. newlineHowever, the previous studies were limited with the combination of UHPC newlineand shear connector.. newline newline
