MAQOLA ANNOTATSIYASI

quote
Pultruziyalangan shisha-tola bilan mustahkamlangan polimer (GFRP) ramkalar va qo'shimcha ishlab chiqarilgan devor panellari harorat, qisqarish va qavatlararo siljishga turlicha javob beradi. Ular orasidagi qattiq bog'lanish nominal yuk ko'tarmaydigan devorni lateral tizimda ishtirok etishiga va mahkamlagichlar yoki bosilgan qatlamlar atrofida mo'rt shikastlanishga olib kelishi mumkin. Ushbu maqola deformatsiyadan ajratilgan interfeys uchun analitik loyihalash tartibini ishlab chiqadi, unda devor og'irligi, tekislikdan tashqari cheklov va tekislik ichidagi harakat alohida komponentlarga biriktiriladi. Tadqiqot ataylab raqamli; laboratoriya natijalari haqida xabar berilmagan. Toshkentdagi ikki qavatli benchmark binosi tartibni namoyish qilish uchun ishlatiladi. Yuklar belgilangan geometriya, zichlik va dizayn kombinatsiyalaridan kelib chiqadi. To'rt murvatli U1 detali podshipnik, aniq kesim tarangligi, kesish chiqishi, yorilish, blok kesish, murvat kesish va mahalliy qatlamlararo skrining holatlariga qarshi qayta baholanadi. EN 13706 E23 minimal xususiyatlari va ASCE/SEI 74-23 qarshilik omillari bilan an'anaviy ichi bo'sh devor orqali murvatli joylashtirish yetarli emas, chunki trubka devorining podshipnik kamayishi hukmronlik qiladi. Ichki tayanch plitalari, ajratuvchi vtulkalar va ikkita M16 murvatli qayta ko'rib chiqilgan o'rindiqli qisqich qisqa muddatli 35,0 kN reaksiya va doimiy yukni tekshirishni qondiradi; eng yuqori doimiy yukdan foydalanish 0,94 ni tashkil qiladi. 3,6 × 3,0 m devor moduli uchun faktorlangan og'irlik 22,95 kN va to'rtta pastki tayanchning har biridagi reaksiya 7,46 kN ni tashkil qiladi. Shamol yuki konverti 1,20 kPa va yon langar uchun 3,24 kN beradi. Tasdiqlanmagan elastik chegirma olib tashlanmaganda talab qilinadigan bir tomonlama harakatlanish 37,52 mm ni tashkil qiladi, bu 95 mm tirqishga olib keladi. 10% devor ishtiroki chegarasi tushunarsiz doimiy sifatida qabul qilinmasdan, davr qisqarishidagi 5% chegaradan kelib chiqadi. Maqola analitik xulosalarni qurilishda foydalanishdan oldin talab qilinadigan sinovlardan ajratadi.
