MAQOLA ANNOTATSIYASI

Ushbu tadqiqot O'zbekistondagi M-41 avtomobil yo'lidagi ko'prikda o'tkazilgan dala sinovlari natijalariga asoslanib, Abaqus dasturiy ta'minoti yordamida CFRP laminatlari bilan mustahkamlangan 12 metrli temir-beton ko'prik to'sinining keng qamrovli chekli elementlar (FE) tahlilini taqdim etadi. Ishning yangiligi real ko'prik ma'lumotlaridan modelni kalibrlash va tekshirishda foydalanishdadir. Model ikkita konsentrlangan yuk ostida nochiziqli beton harakati, po'lat armatura, yopishtiruvchi bog'lanish va CFRP xususiyatlarini simulyatsiya qiladi. Natijalar CFRP bilan mustahkamlashdan so'ng egilish qobiliyatining 22-25% ga oshganini va o'rta oraliq egilishining 19% ga kamayganini ko'rsatadi. FE tahlili xizmatdagi temir-beton ko'priklarning yuk ko'tarish qobiliyatini yaxshilashda CFRP laminatlarining yuqori samaradorligi va ishonchliligini tasdiqlaydi.
