Maqolada ko‘p qavatli binolarda lift shaxtasi konstruksiyasining seysmik va dinamik yuklar ta’siridagi kuchlanganlik
holatini baholash masalasi ko‘rib chiqilgan. Tadqiqotda lift shaxtasi, bino konstruksiyasi va lift tizimining o‘zaro
dinamik ta’siri hisobga olinib, seysmik ta’sir vaqtida konstruksiyada yuzaga keladigan siljishlar, tezlanishlar, ichki kuchlar
va kuchlanishlarni aniqlashga e’tibor qaratilgan. Hisoblash modelida lift shaxtasining konstruktiv qattiqligi, massasi,
bino bilan bog‘lanish shartlari hamda yuklarning vaqt bo‘yicha o‘zgarishi asosiy parametrlar sifatida qabul qilindi. Seysmik
ta’sirni baholashda modal va vaqt bo‘yicha dinamik tahlil usullaridan foydalanish imkoniyati ko‘rib chiqildi. Natijalar
lift shaxtasining qattiqligi va binodagi joylashuvi konstruksiyaning umumiy dinamik javobiga sezilarli ta’sir ko‘rsatishini
ko‘rsatishga qaratilgan. Olingan natijalar asosida lift shaxtasi konstruksiyasining seysmik mustahkamligini oshirish va ko‘p
qavatli binolarda uning ishonchli ishlashini ta’minlash bo‘yicha tavsiyalar ishlab chiqildi
