Abstract

Fiber Reinforced Polymer (FRP) adalah material komposit yang berfungsi sebagai perkuatan untuk meningkatkan kapasitas kekuatan elemen struktur. Pada umumnya perkuatan diperlukan sebagai akibat perubahan fungsi bangunan atau memenuhi persyaratan terhadap beban desain gempa yang diperbaharui. Perkuatan kolom beton  persegi dengan FRP memerlukan penelitian lebih lanjut terkait dengan sudut pada  penampang persegi yang menyebabkan terjadinya konsentrasi tegangan. Penelitian ini menggunakan Jaringan Saraf Tiruan (JST) untuk memprediksi tegangan terkekang (f’cc) kolom beton persegi yang diberikan perkuatan FRP. Penggunaan JST dengan 4 hidden layer (J8-4-1) dalam memprediksi 113 benda uji hasil eksperimen memberikan hasil akurat dengan nilai validasi MSE yang optimum yaitu sebesar 0.00131 dengan nilai korelasi R baik pada fase training, fase validasi maupun fase uji berturut-turut adalah sebesar 0.992, 0.982 dan 0.983.  JST J8-4-1 memberikan hasil prediksi tegangan dengan korelasi yang lebih baik dibandingkan dengan usulan metode analisis yang telah dilakukan pada beberapa penelitian terkait perkuatan kolom persegi dengan FRP. Analisis dengan JST juga memberikan gambaran yang akurat mengenai korelasi kenaikan radius kelengkungan sudut kolom persegi terhadap peningkatan tegangan terkekangnya. Hasil prediksi JST konsisten dengan beberapa studi eksperimental yang telah dilakukan serta konsisten dengan formula yang diberikan dalam ACI 440.2R- 2017.

Abstract

Earthquakes are unexpected natural disasters that can cause severe damage to buildings, especially those not compliant with standards. The construction of educational facilities, in this case, school buildings in Indonesian territory located in earthquake-prone areas, needs special attention. The Cianjur earthquake that occurred in 2022 resulted in damage to several school buildings in the affected area. The Community Service activities in this article investigate 9 Junior High School buildings and 5 Elementary School buildings in the Cianjur Regency area that experienced minor to severe damage that must be immediately repaired or strengthened. Community service in cooperation with the Cianjur regional government's educational institutions and school personnel impacted by the earthquake. The results of the visual investigation of the school building show damage from moderate to severe levels and require immediate action, considering that Cianjur has a high earthquake risk. Repairs and strengthening can be carried out according to the damage level, starting from adding new columns for beams that experience excessive deflection due to dimensions that do not meet the requirements or adding reinforcement using FRP. Columns with dimensions that do not meet the requirements, dimensions can be added even if there is no significant damage visually during the investigation.

Abstract

Research related to the estimation of the remaining strength of cement-based buildings provides benefits, namely the investigation of the level of damage to the building, with the aim of determining how severe the damage category of a building is. The purpose of the community service (abdimas) activities carried out is the investigation of damage to the school building, namely Pasiripis Public Elementary School, Lembang District, West Bandung Regency, to produce a technical recommendation document for repairing the school building. To achieve this goal, several abdimas activities have been carried out, namely the stages of measuring the building, identifying building damage, structural analysis to determine the building's ability to work loads, making a 3D model of the existing building, and calculating the budget plan related to the repair of the building. Presentation of documents and building modeling as a reference in the technical implementation of repairs, cost estimation, calculation of work volume, and a structured implementation plan using a Gantt chart to ensure timeliness and control of work progress. The assessment covers two main aspects: Process Evaluation and Outcome Evaluation. Process evaluation focuses on verifying the accuracy of data at each step, from cross-checking mapping and field measurements, to the suitability of the 3D visual design, and to the validity of the structural analysis. The outcome evaluation aims to verify the quality and safety of the repaired structure and ensure that major damage to the building has been resolved.
