Abstract: To study the impact of the strain rate effect and size effect on the compressive dynamic behavior of lightweight concrete (LC), 3 cube sizes and 10 strain rates were set up, and uniaxial compression tests were conducted ...

Abstract: Concrete is obviously affected by the loading strain rate, and concrete exists in the state of shear multiaxial stress in practical engineering. Studying the dynamic response of concrete under multiaxial shear states ...

Abstract: A shield tunnel is an assembled structure that is composed of segments and connecting bolts, and its longitudinal seismic response needs to be investigated. Bolt prestress is a common measure for shield tunnels, and ...

Abstract: To examine the uniaxial behaviors of plain concrete and lightweight aggregate concrete under dynamic loadings, the plain concrete specimens and lightweight aggregate concrete specimens prepared by shale ceramsite were ...
