“…For bio-based FRP to be compared with existing commercial FRP materials like CFRP and glass fibre reinforced polymer (GFRP), the material has to be considerably thicker to match their strength. Developed bio-based FRPs by some researchers were able to perform similar to CFRP composites in strengthening RC beams [84][85][86][87][88][89][90]. Also, for these bio-based FRPs to be used in the field, durability issues must be adequately addressed.…”

“…Researchers have predicted the behaviour of bio-based FRP systems in various ways. Some authors predicted the behaviour of RC strengthened beam numerical modelling with software like ABACUS [3,86], ANSYS [6,76] and ATENA [70,91], while some have used artificial neural network modelling [74,95]. Some authors have also adopted analytical methods.…”

Penyelidikan pada bahan komposit terus mengalami perkembangan yang signifikan sejalan dengan kebutuhan manusia akan produk yang lebih ringan, kuat, mudah bentuk, ramah lingkungan, dan berbiaya murah. Bahan alternatif yang bersumber dari bahan alami seperti tanaman Jute yang digabungkan dengan bahan sintetik e-glass menjadi perioritas utama untuk mencapai target bahan yang kuat namun ramah lingkungan. Dalam studi ini, penyelidikan bertujuan untuk analisis pengaruh pemberian bahan komposit laminat hibrid lembar serat jute anyaman dan e-glass (KLHJG) pada beton kolom berbentuk silinder dengan cara menghitung pesentase pola retak (PPR) yang terjadi dan selanjutnya dibandingkan dengan kekuatan tarik belahnya (KTB) untuk mendapatkan fenomena yang terjadi. Spesimen dicetak dengan menggunakan standar ASTM D496 untuk pengujian kekuatan tarik belah. PPR dihitung dengan menggunakan metode Histogram dengan bantuan software Adobe Photoshop. Hasil yang diperoleh ialah pemberian KLHJG pada beton kolom silinder mampu meredam PPR hingga dibawah 20%. Akan tetapi, pada komposisi JGJG dipeorleh PPR yang lebih besar dari 30% yang mengindikasikan bahwa pada komposisi ini tidak begitu efektif melindungi struktur beton terhadap beban eksternal yang dikenainya.

This paper presents an experimental investigation of the use of composite polymer mortar (CPM) and steel strands wire mesh (SSWM) to strengthen reinforced concrete (RC) beams in shear. In order to maximize the shear resistance of the steel strands, a new type of anchor device called wedge‐shaped steel plate hoops (WSSPHs) was developed. And the study aimed to examine the effect of shear‐to‐span ratio and prestressing level on the mechanical properties of the beams. A total of nine beams were constructed and tested under four‐point bending monotonic load, comprising three control beams and six strengthened beams. The study analyzed the damage modes, load‐deflection curves, strength, stiffness, and ductility of the beams. The test results indicated that (1) the mechanical properties of the strengthened beams were improved, with the shear capacity improving by 38.47%–71.37% after strengthening. (2) It was observed that SSWM could be utilized more effectively in high shear‐to‐span ratio beams among the strengthened beams with the same prestressing level. (3) Additionally, the larger prestressing level was found to change the design damage mode of the test beams, with RB‐2.5‐0.5 failing in bending. Finally, a model was proposed to predict the shear capacity of the test beams based on the specification GB 50011‐2010. The model considered the effect of the initial prestressing of the steel strands.
