Analisa Pengaruh Penambahan Carbon Fiber Reinforced Polymer Sebagai Tulangan Eksternal Terhadap Keruntuhan Geser dengan Efek Samping Peningkatan Lentur

Abstract

One attempt to improve the latitude and shear capacity is to plan a structure with maximum reinforcement stirrups, it is often overlooked by some people that design errors resulting structure can not withstand shear . In this case , there are several ways you can do to increase the shear capacity of a particular structure in the case study was conducted on beams with Carbon FRP reinforcement with U Wraping method. Evident in the analysis carried out in both the theoretical and testing in the laboratory, Carbon FRP are very effective in improving the style of latitude and shear capacity, in addition to the increase in flexural capacity also occur with this method. Referring to the regulation ACI 440, the calculation of shear capacity in the study were able to increase by 86.95 %. This proves U Wraping method by using Carbon FRP is effectively used as external reinforcement and this method can be used on the damaged structures such as cracks on the beam. On the addition of external reinforcement beams, columns and other structures such as plates by using Carbon FRP is also more efficient and practical when compared with conventional usual way due to the use of Carbon FRP materials are thin, lightweight and does not take place in the execution and easy in implementation
