TINJAUAN KUAT LENTUR CARBON FIBER REINORCED POLYMER PLATE (CFRP PLATE) PADA STRUKTUR BALOK BETON BERTULANG DI HKBP TITI LAYANG

Abstrak

The  reinforced concrete beam structure is an important part of the building structure and aims to carry transverse loads in the form of flexural, shear and torsional loads, reinforced concrete beams are very easy to experience shear cracks and flexural cracks if their strong capacity does not meet the load carried. Along with the times, the reinforcement mechanism  Structures with larger capacities are always investigated for engineering needs, one of which is Carbon Fiber Reinforced Polymer Plate. Therefore, in this study, research will be conducted on the flexural strength of Carbon Fiber Reinforced Polymer which has been used as a reinforcement for the HKBP Titilayang beam structure.  , The structure of the first floor beam in the building as a whole experienced flexural cracks and shear cracks which always widened after the addition of functions to the building.  This analysis was carried out using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses method, or often referred to as PRISMA, based on the ACI 440 and experimental data of the theorists on the flexural strength of CFRP plates.  After analyzing the structure of the HKBP Titilayang beam for three months from the first day it was completed reinforced with CFRP plates, the result is that the flexural cracks that always widen on the surface of the concrete beam of the first floor of the HKBP Titilayang building do not increase anymore.
