Experimental Study of the Influence of Multiple Cyclic Loading on the Static Modulus of Elasticity of Hardened Concrete

Popis výsledku v původním jazyce

The study of concrete properties currently emphasises not only strength, e.g. compressive, but also elastic properties, such as the static modulus of elasticity [1, 2]. This property of hardened concrete affects primarily its deformation under load, the magnitude of deformation or shrinkage. Generally speaking, the higher the value of the modulus of elasticity, the lesser the degree to which a structure deforms. It could be said that concrete during its service life in a structure alternates between states of being loaded and unloaded. If a concrete structure is repeatedly acted upon by external mechanical loads during its service life, it can be considered as subjected to multiple cyclic loading. These cycles are not regular and may occur throughout the structure’s existence based on its purpose and manner of use. This paper deals with the dependence of the value of the static modulus of elasticity of concrete in compression on the number of loading cycles. It is assumed that the value of the static
