Optimum Design Of Multi Storied Building With Fatigue Loads And Blast Loads

Abstract

newline ABSTRACT newlineThe present thesis illustrates the blast loading and the fatigue loading analysis of RC newlinemembers when subjected to cyclic loading and forces caused by explosives. Experiments newlinewere conducted on steel specimens acquiring a tensile strength of 550N/mm2 with both newlinelow and high cycle fatigue loading patterns and the cycles at the point of failure were newlinerecorded with the given load and frequency conditions. The behaviour of multi-storied newlinebuildings was studied by exposing them to fatigue loads using time history analysis. A newlinesoftware analysis using ETABS 20 was done to analyse the structure and the behaviour newlineof reinforced concrete members under various fatigue conditions and redesigned to newlinewithstand the load applications. newlineTo analyse the stability of a building, a study was conducted on different newlineparameters viz; story drift, base shear, base reactions and story displacement. This was newlinedone in two conditions. In the first condition, without any shear wall, responses were newlinerecorded. In the second condition, shear wall responses were recorded. Apart from newlinenatural calamity, numerous manufactured disasters are compelling structural engineers to newlinecome up with more advancement in designing the structures. One of the most significant newlinemanufactured disasters is growing terrorist attacks. To design blast-resistant buildings, newlinedynamic loads must be considered as an essential parameter. This study aims to newlineunderstand the design theories that safeguards structure design against the harmful effects newlineof explosions. Firstly, different types of explosives are explained, and then the detailed newlineprocess of a blast is illustrated for clarity on the behaviour of explosives on buildings; newlinestudying the characteristics of an explosion will help to design blast-resistant structures in newlinethe best possible manner using requisite knowledge. newlineThe performance of reinforced concrete structures is affected by the behaviour of newlinethe stress-strain parameters of the steel. It may have a non-elastic character with the newlinefractured nature in the longitudin
