“…Tetapi karakteristik getaran khususnya pada kapal bermaterial FRP belum banyak [6]- [8]. Setiap material punya kelebihan dan kekurangan dari berbagai segi karenanya beberapa peneliti melakukan kajian mengenai kemungkinan dilakukan kombinasi dua jenis material seperti baja dan FRP bahkan material sandwich yang sekarang sementara menarik perhatian para perekayasa material [9], [10]. Bahkan material FRP digunakan juga untuk memperkuat penyambungan dua jenis material berbeda [11].…”

Salah satu sumber getaran pada kapal adalah akibat kerja mesin induk. Material struktur menjadi salah satu penentu besarnya amplitudo yang terjadi. Kapal monohull dengan penggunaan 3 mesin menjadi objek dari penelitian ini. Getaran pada dinding di ruang penumpang menjadi penting ketika amplitudo yang terjadi mengganggu penumpang di dalamnya. Karakteristik getaran perlu diketahui agar dapat dicarikan solusi untuk mengatasinya. Pengukuran getaran langsung di kapal menggunakan vibrometer dan dilanjutkan dengan menggunakan simulasi hingga diperoleh karakteristik getaran pada dinding kapal ini. Hasil pengukuran di lapangan menunjukkan angka amplitudo di atas 0,2 mm melebihi batas yang diijinkan yaitu 0,02 mm. Diperlukan simulasi untuk menggambarkan distribusi getaran pada dinding kapal. Hal ini untuk mempermudah proses analisa pola distribusi getaran . Hasil simulasi pada dinding kapal menunjukkan bahwa getaran dalam arah vertikal mempunyai nilai amplitudo yang lebih besar dan frekuensi lebih rendah dibandingkan arah getaran horisontal. Hal ini mengindikasikan konstruksi dalam keadaan buruk jika frekuensi natural dari sistem tersebut mendekati nilai frekuensi eksitasi akibat operasional mesin. Getaran yang diteruskan dari sumber getaran tidak teredam dengan baik dalam arah vertikal. Hal ini ditunjukkan dengan besarnya nilai amplitudo yang mencapai 10 kali lebih besar dari amplitudo arah getaran horisontal. Penelitian ini menunjukkan diperlukan peredam pada bagian dinding kapal agar getaran dalam arah vertikal dapat dikurangi. Adapun cara meredam getaran dapat dilakukan dengan berbagai cara. Solusi untuk mengurangi getaran ini menjadi peluang untuk dilakukan penelitian lainnya.

The in-situ health condition of carbon fiber reinforced polymer (CFRP) reinforced structures has become an important topic, which can reflect the structural performance of the retrofitted structures and judge the design theory. An optical fiber-based structural health monitoring technique is thus suggested. To check the effectiveness of the proposed method, experimental testing on smart CFRP reinforced steel beams under impact action has been performed, and the dynamic response of the structure has been measured by the packaged FBG sensors attached to the surface of the beam and the FBG sensors inserted in the CFRP plates. Time and frequency domain analysis has been conducted to check the structural feature of the structures and the performance of the installed sensors. Results indicate that the packaged Fiber Bragg Grating (FBG) sensors show better sensing performance than the bare FBG sensors in perceiving the impact response of the beam. The sensors embedded in the CFRP plate show good measurement accuracy in sensing the external excitation and can replace the surface-attached FBG sensors. The dynamic performance of the reinforced structures subjected to the impact action can be straightforwardly read from the signals of FBG sensors. The larger impact energies bring about stronger impact signals.

“…Fiber-Reinforced Polymer (FRP) is made of high-performance fiber and resin matrix through a special production process. It has excellent properties of lightweight [ 2 , 3 ], high strength [ 4 , 5 ], corrosion resistance [ 6 , 7 , 8 ], and fatigue resistance [ 9 , 10 ]. In recent years, FRP has gradually attracted more popularity in the field of civil engineering [ 11 , 12 , 13 ].…”

Aiming at the problems of a large number of corrosion and fatigue damage of the current prestressed steel strands, this paper adopts carbon fiber-reinforced composite (CFRP) strand with better corrosion resistance and fatigue resistance and uses it in concrete structures. The bond anchorage is usually used to anchor CFRP tension members, which bonds the CFRP through the binding medium. Through experimental research on the CFRP strand bond anchorage, the inner taper of the CFRP prestressed strand cone was anchored and the influence of different anchor lengths and bonding media on the anchorage performance was determined. The test results demonstrate that the taper of the conical anchorage described in this paper is a key factor affecting its anchorage performance and increasing the inner taper within a certain range is beneficial to improving the anchorage performance of the conical anchorage. The bonded anchorage of the CFRP prestressed strand with a 200 mm anchor is the most reliable and efficient, as the taper of the 200 mm anchor is the largest. The average anchoring efficiency coefficient of the 200 mm anchor was 96.4%, which is 3.7% and 2.6% higher than the average anchoring efficiency coefficient of 220 mm and 250 mm anchors, respectively. The anchoring efficiency of the anchor is also high (94.1%) when the epoxy resin mortar is used as the bonding medium. Moreover, after an appropriate amount of quartz sand is added to the epoxy resin, the overall comprehensive performance of the anchor can be improved to a certain extent and the stress of the CFRP strand can be improved. The coupling between ultra-high-performance concrete dry mix (UHPC-GJL) and CFRP strand materials is not suitable for UHPC-GJL being used, as its binding medium as the average anchoring efficiency coefficient is only 44.5% when UHPC-GJL is used as the anchor bonding medium.
