Comparison of Conventional RCC Columns, Steel Columns and Composite Columns
Abstract: Worldwide, the steel industry is expanding almost everywhere. Compared to the USA, EU, and other developed nations, India uses less steel in the construction industry. Additionally, India's cities have some of the highest population densities per square kilometre, which limits horizontal construction growth and favours vertical development. Steel structures are more ductility and can undergo more deflections while concrete structures are larger and attracts more seismic weight. Hybrid construction combines …

Analysis of Tall Structures for Different Stiffness Ratios of Columns to Shear Walls and Column Shortening
Abstract: Differential axial shortening in a structure causes axial force redistribution among columns and walls, and introduces additional forces in the horizontal members such as beams and slab. Hence, it needs to be considered in the design, especially for medium to high-rise buildings. The best way to illustrate differential column shortening is to conduct floor-by-floor analysis, generally known as construction sequence analysis. Commercial software ETABS is available for conducting sequential analysis. …

Different Confinement Pattern and Behavior of Short Concrete Column
Abstract: In recent years, as the economy of country grows, vast construction is done in our country. Among which majority of people have consulted with skilled persons, and there are some who constructed without involvement of professionals. In such scenario professionals to the best of their knowledge followed the techniques as mentioned in IS code for a column. But in those cases where professionals are not consulted and unskilled person construct …

Effect of Strong Column Weak Beam Concept on Seismic Capacity of Buildings of Varying Heights: A Review
Abstract: The strong-column-weak-beam (SCWB) layout philosophy in which plastic deformation is authorized to arise most effective with inside the beams whilst the columns continue to be basically elastic is broadly followed in seismic layout codes for metallic second frames. Under this yield mechanism, the seismic strength is dissipated ordinarily with the aid of using the plastic hinges with inside the beams and on the column bases. The relative plastic flexural capacities …

Lumped Construction Sequence for Column Shortening Analysis in High Rise Building with Outrigger System
Abstract: The exact value of column shortening is not a straightforward task. Various parameters are affected on column shortening results like rate of construction sequence and reinforcement ratio. The building should stand with high stiffness and must be able to resist lateral deformation without having discomfort to the user. The excessive drift is controlled by using outrigger system. In high rise buildings, the construction sequence analysis and conventional sequence analysis are …

Abstract: Steel Fiber Reinforced Concrete (SFRC) possesses many excellent dynamic performances such as; high resistance to explosion and penetration. It has little effect on pre-cracking behavior in uniaxial compression, but substantially enhances its post cracking response. This response leads to a greatly improved ductility and toughness. Steel fibers in SFRC are capable of preventing crack propagation as well as brittle failure of columns under uniaxial compression. To this end, four reinforced …

Effect of Outriggers Location on Performance of RC Building Subjected to Loss of a Column
Abstract: Progressive collapse denotes a failure of substantial part of the structure, causing greater damage to the structure than the initial impact, which has been initiated by failure of a relatively small part of the structure such as failure of any vertical load carrying elements (typically columns). Failure of large part of any structure will result into substantial loss of human lives and natural resources. Therefore, it is important to prevent …
