CFRP RC column Close-in explosion Residual bearing capacity 1. Introduction Deliberate explosions targeting landmark buildings and critical facilities emphasize the need to prevent structures from being subjected to blast loadings.
Seismic Retrofit & Repair STRUCTURAL TECHNOLOGIES
They also explains the single storey industrial building retrofitting, using four different intervention options and concluded that all the retrofitting methods presented in paper lead to a.
Structural Retrofitting And Strengthening By Jacketing, Its Types And
The purpose for strengthening or retrofitting these RC beam-column structural joint includes various factors as concrete which is deteriorating, changes in building utility, structure ageing, corroding reinforcement, design mistakes or construction errors and upgradation in the codal provisions.
Methods Of Retrofitting For RCC Structures What Is Retrofitting?
Cover plates are often added to existing (loaded) steel columns as an effective retrofit method for increasing their compressive design strength. Current bridge design specifications provide equations for calculating the compressive design strength of steel columns. However, these equations cannot be extended to calculate the design strength of.
Jacketing of RCC Column with Concrete Structural retrofitting and
Seismic retrofitting and/or the strengthening of RC columns has been a popular area of research for decades. Currently, reinforced concrete jacketing is considered as the most common technique for repairing and strengthening of deficient and/or damaged RC columns.

The use of wraps around existing deficient columns induces lateral confining stresses in the concrete as it expands laterally in the compression zone as a function of high axial compression strains or in tension zone as a function of dilatation of lap splices under incipient splice failure.

2.2 Column retrofitting. The RC columns thus constructed were retrofitted through the three confining methods of CFRP wraps, CSB, and CSW using unidirectional carbon fibers and Sikadur-330 epoxy adhesive via the wet lay-up process. Based on the manufacturer's catalog, the carbon fibers were 0.17 mm in thickness with an elongation-at-break of.
Soft Story Retrofit 3 Retrofit Construction Methods and How it Affects
Retrofitting refers to the process of upgrading or modifying existing structures, systems, or equipment to improve their performance or make them more energy-efficient. This process is typically performed in older buildings or homes to bring them up to current standards and improve their energy efficiency. Retrofitting of Building
Structural Retrofitting And Strengthening By Jacketing, Its Types And
1. Reinforced Concrete Jacketing It is one of the techniques used to improve or restore capacity of reinforced concrete column. The size of the jacket and the number and diameter of the steel bars used in the jacketing process depend on the structural analysis that was made to the column. Reinforced Concrete Jacketing Process
How to Use Cantilevered Columns Correctly Our Latest SoftStory
Local retrofit technique refers to retrofitting of column, beam, joint, slab, wall and foundation. It is based on the reduction of seismic demands. Types of local retrofitting techniques: Concrete jacketing. Steel jacketing. FRP sheet wrapping

Deterioration of column due to weathering action. Dilapidation of columns. Heavy damage due to other causes like earthquake and fire Advantages of jacketing It increases the seismic capacity of columns. Amount of work is less as foundation strengthening is not required. It increases the shear strength of the column.

Column Retrofitting of reinforced concrete columns using FRP Authors: Omar Mahmoud Menoufia University Amr Essa Menoufia University Omar Hassan Abstract This study evaluates different methods.
Retrofitting Techniques for Existing Damaged Buildings Methods for
Fiber reinforced polymer (FRP) material is commonly applied in retrofitting structures due to the advantages of high strength and well corrosion resistance. Previous studies indicated that retrofitting with FRP sheet was an effective way for protecting the existing structures to resist the blast loads, but little research made comprehensive comparison study on the blast response of RC columns.

Retrofitting of the square columns with FRP sheets Download
The RC column retrofitting is a common research field in seismic studies. It is mainly because the induced seismic energy stress in a building frame structure is dissipated by the displacement of the columns resulting in minor to serious damages based on the magnitude of the earthquake. Therefore, the necessity for repairing arises to
