Abstract

Rehabilitation (improvement) is a process and repairing method or modifying one structure in order to achieve the new operating conditions or increasing the useful life operation. In fact, in designing and implementation the retrofit, we are looking to achieve the new condition for concrete structure in terms of operating or loading. Retrofit operations can be necessity for design errors and problem causes, administrative problems and errors, changes in standards and regulations, increasing the useful life of the operation, changing the structure, increasing the classes and imposed load. Also, damaging in reinforced concrete columns can be cause the irreparable and strong damages. So, study the retrofitting the reinforced concrete columns by Polymer fibers and with different layouts of Polymer fibers. Improvements with Polymer fibers and proper laboratory study have been used in order to validation exam for modeling. Then, proper retrofit layout of Polymer fibers is discussed in Abaqus Finite element software with simulation with several various models. After studying the hysteresis-bar curves transformation, load-displacement curve cover-transformation, Ultimate load and the contribution of Polymer fibers of models was found that samples those have Polymer fibers have a greater ability to more loading bearing and also, have more absorb property and more energy amortization (82 percentage of increasing the capacity) than samples without fiber.
