Review Study on re-strengthening of reinforced concrete circular column using steel strips
Abstract: This technique fixes thin steel plates i.e. steel encasement or tie plates i.e. steel cage around the column with steel angles at each corner, clamped to the concrete and welded together. Adequate tightening of the jackets can be ensured by means of heat tensioning. The use of steel jackets can enhance the shear strength of columns considerably. However, due to their low flexural stiffness they typically have poor confinement efficiency …

Cost Impact of Structural Irregularities
Abstract: Since absolute regularity is an idealisation that seldom exists, building structures are typically irregular. Building irregularities are unavoidable because of the many practical and aesthetic benefits. The performance of buildings subjected to earthquake pressures has revealed that asymmetric and irregular constructions produce more severe damage than regular structures, and the collapse of these structures may be blamed for the majority of human fatalities. Vertical mass inconsistency is commonly due to …
