CONCRETE SUBJECTED TO PULSATING LOAD AND PULSATING DEFORMATION OF DIFFERENT PULSE WAVEFORM

This article describes an investigation carried out to ascertain the way in which the time function or wave form of a pulsating load affects the deformations and degree of fatigue in concrete. It was also the intention to find out the effect a pulsating deformation with different wave form has on load and on the transverse strain. The test procedure and the testing apparatus are described in the article. The test series were divided into (1) controlled load tests and (2) controlled deformation tests. The results show that a rectangular wave form has a greater effect on the deformation in the concrete than the sinusoidal triangular wave form and also causes failure after the least number of load cycles. Concerning the transverse strains, the rectangular pulse had the largest effect only in the controlled load tests. The transverse strains in the controlled deformation tests were greater for a triangular wave form, due to the fact that the rectangular pulse wave form causes a lower load.
