AN EXPERIMENTALLY STUDY ON EFFECT OF RETROFITTING OF EXISTING REINFORCED CONCRETE COLUMNS BY REINFORCEMENT BARS AFTER CONSTRUCTED FROM ONE FACE SEISMIC RETROFITTING METHOD

Time-dependent Seismic Fragility Curves on Optimal Retrofitting of Neutralized Reinforced Concrete Bridges

Effect of Reinforcement Grade and Ratio on Seismic Performance of Reinforced Concrete Columns

Reinforcement grades higher than 75 ksi (520 MPa) are not allowed in members that form plastic hinges due to a lack of information on material characteristics and on the seismic performance of columns constructed with high-strength steel (HSS) reinforcement. This research investigated the performance of reinforced concrete columns containing Grade 80 (minimum yield strength of 80 ksi [550 MPa])...

retrofitting of reinforced concrete columns using steel and concrete jacketing tchnique

retrofitting structures is an important issue. structural weakness may be due to changes in design codes or defects in implementation. adding structural floors to the existing structures may also lead to the need for strengthening and retrofitting. retrofitting is possible before the earthquake or may take place as rehabilitation of damaged members after earthquake. elements such as columns in ...

Structural Rehabilitation, Retrofitting and Strengthening of Reinforced Concrete Structures

Reinforced cement concrete is getting extensively used for construction of different type of structures for the last one century. During this period, we have constructed many structures like buildings, bridges, industrial structures, pavement, water tanks etc. using this construction material. These structures have been created with huge investment of resources. It is essential to maintain thos...

Seismic Behavior of Substandard RC Columns Retrofitted with Embedded Aramid Fiber Reinforced Polymer (AFRP) Reinforcement

Many existing reinforced concrete structures were constructed with substandard characteristics. Low quality concrete, poor transverse reinforcement details and insufficient flexural strength are among the most common deficiencies. While substandard structures are in need of retrofitting, particularly in seismic areas, problems such as high costs and disturbance to occupants are major obstacles ...
