Kombinatsiyalashgan po‘lat va bazalt komopzit armaturali temirbeton to‘sinlarni normal kesim bo‘yicha tadqiq qilishda jami 9 xil to‘sinlar tayyorlandi va eksperimental sinovlar o‘tkazildi. Mazkur to‘sinlarning samaradorligi eksperimental sinovdan tashqari sonli tahlil yordamida baholandi. Barcha kombinatsiyalashgan armaturali to‘sinlarda buzilish po‘lat armaturaning oquvchanligi hamda siqiluvchi zonadagi betonning buzilishi bilan kuzatildi, lekin bazalt kompozit armaturalar uzilmasdan qoldi. Kombinatsiyalashgan armaturali temirbeton to‘sinlar sinovidan olingan natijalar odatdagi po‘lat armaturali temirbeton to‘sin natijalari bilan o‘zaro taqqoslandi va xulosalar olindi.
