Retrofitting of concrete structure
This document discusses retrofitting of structures. Retrofitting is required when structures are damaged or do not meet current seismic standards. It summarizes various retrofitting techniques such as adding shear walls, infill walls, steel bracing, wall thickening, wing walls, mass reduction, base isolation, and jacketing structural elements. It provides examples of existing retrofitted structures in Gujarat. Retrofitting increases strength and ductility but can reduce space and increase foundation loads. Materials discussed include steel, fiber reinforced polymer, and reinforced concrete.

CFRP Strengthening of Concrete Beam Shear Cracks
The document discusses using carbon fiber reinforced polymer (CFRP) to strengthen concrete beams experiencing shear cracks. A concrete beam supporting a 200 MT load at each support was originally designed incorrectly as a slender beam rather than a deep beam. Analysis showed the beam was overstressed, exhibiting typical shear cracks. CFRP strengthening was proposed to reinforce the beam without requiring a plant shutdown during repairs. CFRP would be applied to increase the beam's shear capacity and allow it to support the required loads.
Design of Retaining Wall
The document provides details about the Structural Design and Drawing course CE8703 taught at Vivekanandha College of Technology for Women. It includes the course objectives, units covered, outcomes, design and drawing exercises, textbooks and code books referenced. The key topics covered in the course are design and drawing of retaining walls, flat slabs, bridges, liquid storage structures, industrial structures, girders and connections. The course aims to provide students with knowledge of structural engineering design principles and skills to design and draw various reinforced concrete and steel structures.
REPAIRS AND REHABILITATION OF STRUCTURES
This document discusses various techniques for repairing and rehabilitating concrete structures. It covers topics such as concrete deterioration mechanisms, materials used for repair like cement mortars and polymers, and techniques like grouting, jacketing, and external bonding. Assessment of damaged structures involves preliminary investigation, detailed investigation using techniques like core cutting, rebar location, corrosion measurement, and pull-out tests to determine repair requirements. Underwater repair of structures also requires special considerations and techniques.

FRP (fiber reinforced polymers) are a composite material made of fibers encapsulated in a polymer resin matrix. They are used for structural strengthening and repair in construction. FRP provides high tensile strength along the fiber orientation and the resin provides stability, shear strength, and bonding to the substrate. Common fiber types include carbon, glass, and aramid. FRP has advantages over conventional repair methods as it is lightweight, corrosion resistant, and can be applied in occupied spaces. Applications include seismic retrofitting of columns, beams and walls, repairing deteriorated concrete, and strengthening structures like bridges and industrial facilities. FRP installation involves surface preparation, applying primer, saturating fabric with resin, and allowing it to cure. FRP

This document discusses retrofitting techniques for concrete structures. Retrofitting involves strengthening existing structures that may be damaged or undamaged. It is required when structures are subjected to excessive loading, seismic damage, or do not meet current design standards. The objectives of retrofitting are to increase lateral strength, ductility, and provide better connections between structural elements. Common retrofitting techniques discussed include adding shear walls, infill walls, bracing, wall thickening, and base isolation. Local retrofitting involves jacketing beams, columns, and joints using steel, fiber reinforced polymers, or concrete. Examples of retrofitted structures in Gujarat, India are provided.
CE 72.52 - Lecture 8a - Retrofitting of RC Members
The document outlines a presentation on retrofitting concrete structures. It discusses two approaches to retrofitting: global (system) strengthening which adds new elements to enhance stiffness, and local (element) strengthening which targets insufficient member capacities. Examples of global retrofitting mentioned include adding reinforced concrete shear walls and buckling restrained braces. Local retrofitting examples discussed are reinforcement concrete jacketing of columns and beams.

Retrofitting of buildings
This document discusses retrofitting of buildings. It begins with an introduction to retrofitting, which is defined as modifying existing structural members to increase resistance to loads. The document then covers the goals of retrofitting such as increasing lateral strength and ductility. It also discusses the need for retrofitting, including when buildings are not designed to code or seismic zones are upgraded. The stages of retrofitting and methods for assessing building condition are outlined. Common retrofitting techniques like concrete and steel jacketing are described and examples of retrofitted structures in Balochistan are provided.
Seminar_Repair & Restoration_of_Structure
The document discusses repair and restoration techniques for deteriorating structures. It outlines various causes of deterioration like human activity, chemical reactions, moisture, and poor design/construction. Repair focuses on restoring shape and function, while restoration improves structural strength by techniques like crack injection, wall strengthening, and foundation upgrades. Non-destructive evaluation methods like rebound hammer and ultrasound tests are used to assess concrete quality without damage. The case study demonstrates using rebound hammer tests to evaluate different structural members.
Fibre Reinforced Polymer
MBrace is a composite strengthening system that uses carbon fiber sheets bonded to concrete structures with epoxy resin to improve their strength and durability. It has advantages over traditional strengthening techniques like steel plating in that it is lighter, easier to install, and does not change the structure's original alignment. The multi-step MBrace installation process involves surface preparation, application of epoxy primer and saturant, attaching pre-saturated carbon fiber sheets, and optional protective topcoating. MBrace increases structures' load-bearing capacity, ductility, blast resistance, and can be used to retrofit beams, columns, walls, and other elements.
Shear strengthening of structural members
This document discusses various methods for shear strengthening of structural concrete members. It begins by explaining the need for structural strengthening due to factors like increased loads, damage over time, or design/construction errors. Several methods for shear strengthening are then described, including external steel reinforcement, section enlargement, internal steel/FRP reinforcement, post-tensioning, supplemental members, and near-surface mounted reinforcement. The document concludes that a variety of materials and strengthening techniques exist to increase shear capacity depending on the specific application.
IRJET- Experimental Investigation on Seismic Retrofitting of RCC Structures
This document summarizes an experimental investigation into seismic retrofitting of reinforced concrete beam-column joints using concrete jacketing. The study tested control specimens designed to code standards and retrofitted specimens with concrete jackets added. The specimens were subjected to reverse cyclic loading to examine their performance and lateral load capacity. The concrete jackets were intended to improve seismic performance by increasing strength, stiffness, deformation capacity, and connection integrity of the joints. The results provide information on the behavior and effectiveness of reinforced concrete beam-columns strengthened with concrete jacketing under cyclic loading conditions.
