“…Hal tersebut disimpulkan karena balok komposit tidak mengalami kerusakan geser yang dominan pada saat pengujian. Penggunaan laminasi GFRP pada sepanjang area lentur balok adalah metode yang sangat efektif untuk meningkatkan kinerja struktural balok komposit [4]. Penerapan komposit beton dengan kayu laminasi diaplikasikan dengan konektor.…”

Dimensi penampang kayu terbatas karena mengalami kembang susut, sehingga untuk memperoleh dimensi kayu yang besar salah satunya bisa dilakukan laminasi. Balok kayu laminasi dikompositkan dengan pelat beton bertulang menghasilkan bentuk struktur dimana kayu dilindungi oleh pelat beton. Sistem laminasi kayu dalam penelitian ini menggunakan baut perekat dengan Carbon Fiber Reinforced Polymer (CFRP) sebagai perkuatan eksternal. Balok uji terdiri dari balok normal tanpa perkuatan (BLN-00) dan balok uji dengan perkuatan eksternal lapisan CFRP (BLF-01). Penelitian ini dilakukan eksperimen dengan metode Displacement Control. Balok uji dibebani satu beban terpusat statik monotonik di tengah bentang dengan kecepatan konstan 0,05 mm/dtk sampai runtuh. Hasil penelitian menunjukkan bahwa balok uji normal tanpa perkuatan (BLN-00) memiliki kekuatan 52,43 kN, kekakuan 7,06 kN/mm, dan daktilitas 13,42. Sedangkan balok dengan perkuatan CFRP (BLF-01) memiliki kekuatan 65,81 kN, kekakuan 9,33 kN/mm, dan daktilitas 16,85. Selain itu, nilai tegangan geser maksimum yang terjadi pada balok normal sebesar 4,23 MPa dan pada balok dengan perkuatan CFRP sebesar 1,95 MPa.

The paper presents the results of experimental research on unstrengthened and strengthened laminated veneer beams subjected to 4-point bending. Aramid, glass and carbon sheets with high tensile strength (HS) and ultra-high modulus of elasticity (UHM) glued to external surfaces with an epoxy resin adhesive were used as reinforcement. Two reinforcement layouts were used: (1) sheets glued along the bottom surface and (2) sheets glued to the bottom and side surfaces. Based on the test results, the flexural strength, flexural ductility and stiffness were estimated. Compared to the reference beams, the maximum bending moment was higher by 15%, 20%, 30% and by 16%, 22% and 35% for the Aramid Fiber Reinforced Polymers (AFRP), Glass Fiber Reinforced Polymers (GFRP) and Carbon Fiber Reinforced Polymers (CFRP) HS sheets, respectively. There was no significant increase in the flexural bending capacity for beams reinforced with UHM CFRP sheets. Similar values of bending ductility indices based on deflection and energy absorption were obtained. Higher increases in ductility were observed for AFRP, GFRP and CFRP HS sheets in “U” reinforcement layout. The average increase in bending stiffness coefficient ranged from 8% for AFRP sheets to 33% for UHM CFRP sheets compared to the reference beams.
