JAKARTA - Minister of Public Works and Public Housing (PUPR) Basuki Hadimuljono said that support for innovation and technology is important in infrastructure development to be faster, accurate, efficient, and of high quality. create added value and sustainable development so that the benefits of infrastructure can be felt by future generations," he said in a written statement received in Jakarta, Friday April 15. The Ministry of PUPR continues to be committed to realizing reliable and sustainable infrastructure development throughout Indonesia. One of them is by innovating the strengthening of the "existing" infrastructure structure. In fulfilling the reliability requirements of the "existing" building, sometimes it is necessary to retrofit or retrofit the structure. It is intended to withstand higher loads, correct loss of strength due to damage, correct design flaws or performance weaknesses or increase "ductility" which is generally achieved using conventional construction materials and techniques. One of the alternative materials for reinforcement of "existing" structures is fiber. "reinforced polymer" (FRP). FRP material is a material that is lightweight, non-corrosive, and has high tensile strength. These materials are available in several forms, from factory-manufactured tension-printed laminates to dry fiber sheets that can be wrapped to conform to the geometry of the structure prior to addition of polymer resin. The relatively thin profile of the FRP system is often used for structures where aesthetics or accessibility is a concern. priority. The FRP system can be used in areas with limited access when conventional techniques are difficult to apply. To increase understanding of the use of FRP materials in retrofitting "existing" structures, the Ministry of PUPR through the Directorate of Settlement and Housing Engineering (BTPP) of the Directorate General of Human Settlements held a Technical Guidance on Strengthening Structures " Existing" Using FRP Material.
Director of Settlement and Housing Engineering Dian Irawati in her speech said that the reinforcement of concrete structures using FRP material is regulated in 6 SNIs, namely SNI 8970:2021, SNI 8971:2021, SNI 8972:2021, SNI 8973:2021, SNI 8974:2021, and SNI 8975:2021. "The SNI related to strengthening concrete structures using FRP has been prepared with the aim of ensuring the safety and strength of the "existing" structure by establishing complete requirements and calculations to increase the capacity of the structure to bear the load," said Dian. Dian added that FRP reinforcement is expected capable of providing increased strength and ductility to the "existing" structure. This is in line with the mandate to fulfill the security aspects contained in Law no. 28 of 2002 concerning Buildings.
