Title: Compressive Strength of Plain Concrete Under Multiaxial Loading Conditions
Author(s): Laddie L. Mills and Roger M. Zimmerman
Publication: Journal Proceedings
Appears on pages(s): 802-807
Keywords: axial loads; biaxial loads; combined stress; compressive strength; failure mechanism; plain concrete; research; triaxial loads.
Abstract:The testing of plain concrete under combined compressive loads has largely been under conditions where two of the three principal stresses were equal. Thus failure criteria under general loading conditions have been unavailable. This study involved the direct loading of cubic shaped specimens from each of three orthogonal axes, By varying the loading conditions along these axes, uniaxial, biaxial, and triaxial states of stress were obtained. Experimental data from 107 tests were obtained and used to generate a generalized failure criterion for this type of loading. A feature of the experimental program was the minimization of surface friction along specimen loading surfaces through the use of pads of two polyethylene sheets with an intermediate layer of grease.
