Numerical Simulation Reinforcement of RC T-Beam with Carbon Fiber Reinforced Polymer (CFRP)
No full textMany infrastructures damaged are due to environmental, inadequate maintenance, and natural disaster like an earthquake. Some structures in Indonesia were built using the old code design, which was unsafe when compared to the new code. The structure needs to be strengthened to increase the safety level and extend its service period. One solution to the problem is to enhance the structure using synthetic wraps or Carbon Fiber-Reinforced Polymeric (CFRP). This research simulates the reinforced concrete T-beam with CFRP by numerical analysis following the predecessor experimental study. The numerical analysis of reinforced T-beam with CFRP was modeled using finite element method. The concrete damage plasticity model for the concrete material was adopted to idealize the concrete material. Also, the interaction property between the CFRP and concrete to be idealized as a perfect bond that is constraint-tie and Hanshin damage for CFRP properties that applied as a composite layup. The numerical analysis results achieve a good agreement with the predecessor's experiments in the term load–displacement curve, bending moment capacity, and failure mode. Although the finite element generated more less similar results with the experiment, the T-beam's failure mode was slightly different in experimental compared with the finite element results. The possible reason might be the experimental study has a failure mode of debonding between interface concrete and CFRP. However, the result of the finite element has a similar failure mode with a normal specimen with a positive post-yield stiffness. In future work, the effect of bond interaction between the CFRP and concrete need to be idealized as contact, or epoxy should be modeled between the CFRP and the concrete. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd
The Comparison of Bond Strength between Geopolymer Concrete and OPC Concrete for Plain Reinforcing Bars
No full textThis paper describes the research on bond behavior of plain reinforcing bars in geopolymer and normal concrete. The geopolymer concrete in this research was made of class F fly ash taken from Tanjung Jati Electric Steam Power Plant (PLTU) with Sodium Hydroxide (NaOH) and Sodium Silicate (Na2SiO3) as alkaline activator, added in the mixture. The effect of bar size was studied by varying the bar diameter in range 10 mm to 19 mm. Each bar was casted in the center of concrete blocks made of geopolymer as well as normal concrete. Pull-out tests were carried out to the specimens that have reached 28 days of age. The test results show that the bond behavior of geopolymer concrete differs substantially from normal concrete, where geopolymer concrete has a higher bond strength when compared to normal concrete with identical concrete strengths
Behavior of Geopolymer Concrete Confined by Circular Hoops
No full textThis paper discusses the behavior of geopolymer concrete subjected to passive confinement under compression loads. The confinement is induced by the use of lateral hoops, assembled from un-deformed reinforcing bars. To compare the effect of confinement, identical specimens were produced using conventional concrete with the similar concrete compressive strength. The cylinder specimens were 100 mm in diameter and 200 mm in height, and the hoops were placed on the outer most fibers of the cylinders, perpendicular to the line of loading, with no concrete cover. The parameters analyzed in this study were the steel bar to concrete volumetric ratio, the hoop spacings and the steel yield stresses. The experimental results show that unconfined geopolymer concrete were very brittle compared to the unconfined Portland cement concrete. The strength enhancement (K value) of the confined geopolymer concrete was higher than K value of Portland cement concrete. Confined geopolymer concrete also has better deformability compared to the confined Portland cement concrete. The average confinement effectiveness of geopolymer concrete also has a higher value than that commonly used in the Indonesian Concrete Standard (SNI), that is 4.1. The results were further assessed to the most recent experimental test results conducted in this area.</jats:p

No full textPitting corrosion often leads to the creation of small holes in steel tubular member of platform structures when a protective coating is damaged. A single pit on slender compression element can cause a significant reduction in the buckling capacity of the member. Euler formula is no longer applicable for determining the critical buckling load when cutout presence on the member. This research was conducted to numerically study the effect of a circular hole on the buckling capacity of slender steel tubular member. A variation on hole positions was at 0.125 L, 0.25 L, 0.375 L, and 0.5 L, where L is the length of the member. The hole was taken to be 0.5 pipe diameter. Two nonlinear geometric 3D Finite Element models were developed to analyzed the member critical buckling load: (a) buckling analysis, where the problem was formulated as eigenvalue problem based on the nonlinear incremental equilibrium equations, and (b) nonlinear analysis, where the nonlinear equilibrium equations were developed and solved by several schemes to get the load – deflection curve. For the both models, the tubular member was discretized into: (a) shell elements, and (b) solid elements. The numerical results were verified by experimental investigation. The results showed that: (a) the presence of cutout reduced the buckling load significantly, (b) the reduction ranging from 3% to 10% depending on the hole positions, (c) the maximum reduction occurs when the hole position was in the middle of the member length, (d) compared to experimental results, the critical buckling load obtained from buckling analysis deviated 1~4% while those of nonlinear analysis deviated 1~5%, (e) the buckling mode corresponded with member bent away to opposite side of the cutout position.</jats:p
