Abstract

For the past few decades, the construction industry has become more dependent on management and simulation tools, for more accurate and efficient estimation of time, cost, and behavior of projects. Several research have been published in the construction and optimization modeling field; however, few to none have investigated the structure repair process with its different alternatives. For instance, reinforced concrete (RC) structure has been repaired and strengthened with RC Jacket for many decades, till a new system was introduced to the market in the early 90 s that has superior mechanical and durability performance, this system is fiber-reinforced polymers (FRP). FRP was first used in military and aerospace applications for its novel performance and limited size and weight, then it was utilized in some manufacturing industries such as Automotive, Aviation, and finally the construction industry. The utilization of FRP has increased dramatically in the field of structure strengthening for three main advantages over conventional RC Jacketing technique; minimal time of application, limited space needed, and finally its high durability and long service life which makes a more sustainable system. However, the FRP system still has some limitations in some construction codes, such as its strengthening ratio of total element capacity, and high aspect ratio in column dimensions in some cases. In this study, an attempt is made to develop a model using Anylogic software that simulates the structure repair and strengthening process utilizing both RC Jacketing and FRP systems for three types of structural elements columns, beams, and slabs. This model also can perform cost-time-environmental impact optimization to determine how many structure elements of each type should utilize each of the strengthening approaches, taking into consideration the benefits and limitations of each method. The model was verified by considering a set of data from a project, and the results showed the model's optimization efficiency.
