Прочность бетона как сопротивление разрушению

Прочность бетона как сопротивление разрушению

Abstract

There are certain contradictions between theories of destruction and durability of concrete caused by specific properties of this material and their influence on process of destruction at any intense states. The article examines the contradiction between theory and fracture strength of the concrete, which consists in evaluating the significance of different compression and tension resistance. To clarify the relationship between the resistance of the concrete compression and tension-races authors refer to the method of computer simulation. We present results of a re-investigation of the stress-strain state of the prototypes.

Существуют определенные противоречия между теориями разрушения и прочности бетона, обусловленные специфическими свойствами этого материала и их влияния на процесс разрушения при любых напряженных состояниях. В статье анализируется противоречие между теориями разрушения и прочности бетона, заключающееся в разной оценке значимости сопротивлений сжатию и растяжению. Для уточнения соотношений между сопротивлениями бетона сжатию и растяжению авторы обращаются к методу компьютерного моделирования. Приведены результаты исследования напряженно-деформированного состояния опытных образцов.
