Ushbu maqolada turar joy binolarida qo’llaniladigan temirbeton devor panellarining ularga ta’sir qiluvchi doimiy va vaqtinchalik yuklar ostidagi kuchlanish-deformatsion holati tadqiq etilgan. Tadqiqotning asosiy maqsadi panel konstruksiyasining yuk ko’tarish qobiliyati, mustahkamligi, bikrligi va ekspluatatsion ishonchliligini baholash hamda yuklarning konstruksiya bo’ylab taqsimlanish xususiyatlarini aniqlashdan iborat. Hisoblash ishlari sonli modellashtirish asosida amalga oshirilib, panelga yuqori konstruktiv elementlardan uzatiladigan yuklar va ekspluatatsion ta’sirlar hisobga olingan. Hisoblash natijasida konstruksiyada hosil bo’ladigan kuchlanishlar, zo’riqishlar va deformatsiyalar aniqlanib, ularning panel bo’ylab taqsimlanishi grafik tasvirlar va epyuralar yordamida tahlil qilingan. Shuningdek, konstruksiyaning eng ko’p zo’riqadigan qismlari aniqlanib, ushbu zonalarda armaturalashning maqbul yechimlari baholangan. Panel tarkibidagi eshik va deraza ochilishlarining kuchlanish va deformatsiya holatiga ta’siri ham tadqiqot doirasida ko’rib chiqilgan. Olingan natijalar asosida yuklar ta’sirida panelning ishlash xususiyatlari baholanib, konstruktiv xavfsizlikni ta’minlashga qaratilgan armaturalash yechimlari shakllantirilgan. Tadqiqot natijalari turar joy binolarining temirbeton panellarini hisoblash, konstruktiv yechimlarni optimallashtirish va ularning ishonchliligini oshirishda ilmiy-amaliy ahamiyatga ega.
