LIGHTWEIGHT CONCRETE BEAM ELEMENTS SHEAR RESISTANCE MODELS WITH LONGITUDINAL AND TRANSVERSE REINFORCEMENT

Abstract

In world practice, structural lightweight concretes, in particular, expanded clay concrete, are increasingly used in the construction of civil buildings and structures and also transport infrastructure. Despite the fact that lightweight concretes have a combination of high physical, mechanical and operational parameters, studies on the determination of different features in the resistance to the effects of elements from structural light concretes and concretes of normal weight do not stop.

The article discusses the issues of shear resistance of reinforced concrete beam elements made of lightweight structural concretes. Analysis of existing shear resistance models used in domestic and foreign regulatory literature was performed. Database results of experimental studies of reinforced concrete beams made of lightweight concretes with different parameters of variation of mechanical characteristics of materials and structural parameters of samples has been formed.
