Research on Technical Solutions to Renovate the Reinforced Concrete Constructions in Vietnam

Abstract

During the use of constructions, they will be degraded. Due to the negative impact on structures such as increase in vertical load, horizontal windy load need s to evaluate the current state of the constructions before renovating, especially the current state of the main structural system whether necessary to carry out repair and reinforcement or not. In addition, the inspection of the current status constructions before renovating is also the legal basis for the granting of construction permits to renovate and repair degraded works. Reinforced concrete buildings in the coastal areas in Vietnam, in particular, are work ing in the marine environment leading to damage the reinforced concrete construction. It should be significantly noted. Although there have been legal documents related to the inspection of constructions issued in Vietnam, the detailed contents and procedures of institution for each type of construction have not been mentioned yet. Therefore, the topic research paper of “ research on technical solutions to renovate constructions with reinforced concrete structures in Vietnam ” is to improve the quality and efficiency of construction. This investigation in Vietnam is very essential. This study uses the method of surveying the current state of the construction works in use, using the experimental sampling method to analyze and evaluate the damage of the work, then propose typical solutions to repair construction. The purpose of th is study is to provide a process to check the damage of the works, and to propose solutions to repair them. This work is very important and has p ractical significance, helping managers to maintain works better.
