Abstract
Способ экспериментального определения статико-динамических диаграмм бетона с учетом трещинообразования, заключающийся в закреплении опытного бетонного образца в виде призмы между несущими плитами испытательного стенда с использованием центрирующего устройства, обеспечивающего, центральное приложение сжимающей нагрузки в процессе нагружения, и регистрации усилия и деформаций призмы во времени с использованием динамометра и тензостанции, отличающийся тем, что нагружение осуществляют через рычажную систему в два этапа: на первом - ступенчатое статическое нагружение образца до заданного уровня в различных долях от нагрузки трещинообразования посредством укладки штучных грузов на грузовую платформу, на втором - мгновенное или ступенчатое динамическое догружение падающим при уменьшении силы тока в электромагните грузом, ось центра тяжести которого совпадает с осью грузовой платформы.The method of experimental determination of the static-dynamic diagrams of concrete taking into account crack formation, which consists in securing the experimental concrete sample in the form of a prism between the bearing plates of the test bench using a centering device that provides a central application of compressive load during loading, and recording the forces and deformations of the prism in time with using a dynamometer and strain gauge, characterized in that the loading is carried out through the lever system in two stages: in the first - with upenchatoe static loading the sample to a predetermined level in various parts of the load cracking by stacking piece goods on the loading platform, the second - the instantaneous or stepwise dynamic dogruzhenie falling when the current in the electromagnet power load, the center of gravity axis of which coincides with the axis of the loading platform.
