Reinforced concrete (RC) columns can be effectively rehabilitated or strengthened by externally bonded fiber-reinforced polymer (FRP) wraps, which improve the axial load capacity and ductility of these through a confinement effect. Modern design codes require that seismically designed RC have significant minimum amounts both longitudinal transverse steel. This steel apply considerable confining...

The concept of cold-formed light steel framing construction has been widespread after understanding its structural characteristics with massive research works over the years. Connection serves as one of the important elements for light steel framing in order to achieve its structural stability. Compared to hot-rolled steel sections, cold-formed steel connections perform dissimilarity due to the...

Over the last two decades, rubberised concrete has emerged as a promising sustainable solution for structural members that possess capacity high energy dissipation, damping potential, and ductility. The literature is replete with some effective confinement techniques to negate effect of reduction columns due introduction rubber particles. These ideas have innovated concrete-filled tubular more ...

In this paper, the initiation and propagation of structural damage in a building due to the truck collision to one of its corner columns were investigated. For this purpose, a three-dimensional 4-story moment resisting steel frame with intermediate ductility was considered. The structure was designed using ETABS software under standard dead, live, and earthquake loads, and then impact loading w...

The application of steel fiber reinforced polymer (SRP) as a means of increasing the capacity of masonry columns is investigated in this study. The behavior of 23 solid-brick specimens that are externally wrapped by SRP sheets in low volumetric ratios is presented. The specimens are subjected to axial monotonic load until failure occurs. Two widely used types of masonry columns of differing squ...

the use of polymer composite (frp) as a reinforcement material for the repair and strengthening of important components of reinforced concrete structures, particularly columns, has found wide spread. in this study, the effect of intermediate layer on improving the confinement behavior of reinforced concrete columns has been investigated. to achieve the objectives of the study, 14 cylindrical re...

Glass fiber-reinforced polymer (GFRP) reinforcements are useful alternatives to traditional steel bars in concrete structures, particularly vertical structural elements such as columns, they less prone corrosion, and impart increasing strength endurance of buildings. There is limited research on the finite element analysis (FEA) behavior hollow glass reinforced (GFRPRC) columns. The portion can...

Composite concrete Filled Tubular Steel (CFT) members, which have excellent deformability due to the well-known confined and constrained interaction between steel tube concrete, largely been utilized as bridge piers or columns in high-rise buildings, resulting increased strength decreased column size. This study examined experimental performance of filled with reactive powder (RPC) under axial ...

Accurate constitutive models of the constituent materials in a reinforced concrete (RC) section, namely, unconfined concrete, confined concrete and reinforcing steel are necessary in fiber-based discretization of RC components for use in nonlinear analysis of RC structures. This paper examines the sensitivity to different constitutive models in predicting the inelastic seismic behavior of RC fr...

The seismic performance of reinforced concrete (RC) columns retrofitted using the steel plate sandwich method bonded with prestressed PC bars was compared in both in-plane and out-of-plane directions. Therefore, bending strength, initial horizontal rigidity, cumulative energy absorption improved.
