Resource-energy saving structural system for residential and public buildings with a preset level of structural safety
The architectural-structural solution for pre-fabricated residential and public buildings with an internal supporting framework of reinforced concrete frame-panels designed with a preset level of structural safety is proposed. Cost of buildings of proposed type is by 20-25 % lower than in a brick variant. Total labor costs for their construction are lower by 30 % at least, construction time is reduced in 1.5-2 times. The results of experimental and theoretical studies on the development of the theory of structural safety of buildings bearing systems under design and beyond- design actions are presented; they show that the sudden application of beyond-design load to the loaded statically indefinable system causes the dynamic loading of all elements of the system.
