The strength of the concrete under longterm loading

Abstract

It is allowable to predict the strength of concrete under longterm loading if the loading influense on phisycal-mechanical properties of structural concrete. Experimental and theoretical data of compressive-tensile strength of concrete under longterm loading are generalize in this work. The longterm and shortterm continuous loading differently acts the strength of concrete. The original testing method allowed to calculate the strength of concrete during compressive-tensile longterm loading. Analysis of concrete structures changes during the loading, working state and failure are presented
