The FEM Analysis of Size Effect on Prism Concrete Specimens with Different Lengths under Loads of Axial Compression

Abstract:

Four prism concrete specimens with same height, same width, but different lengths is simulated in using ABAQUS FEM analysis software. The simulation work is conducted under monotonic axial compression loading, and its purpose is to research the size effect of prism concrete specimens, primarily to study the effect of specimen length on the axial compressive strength. The stress-strain relation of the specimen is analyzed. The results indicate that, for different lengths of specimens, their axial compressive strengths are quite different and the size effect on them is much obvious. The compressive strength improves gradually with the increasing of length, and size effect on transverse and vertical constraint stress of core concrete area is much distinct as well. Meanwhile, it can be obtained that the standard design method of the structures and components is conservative and of adequate security.
