Experimental Study of the Creep Effect on the Mechanical Properties of Concrete

Figure 16

Tensile strength of creep-loaded specimens (relative to the average of the unloaded specimens) vs. the creep loading level. The error bar represents the maximum and minimum relative strength values (for 3 specimens). The variabilities of 3 accompanying control specimens ranged between ±0.02 for a 50% loading level; +0.20 and −0.16 for an 80% loading level; and +0.12 and −0.09 for a 90% level.
