摘要：
The effects of long-term loading on plain (PLC) and steel fibre reinforced concrete (SFRC) rings under two-edge sustained load at five different levels were investigated. The results have led to the conclusion that a linear relationship between the initial and time-dependent deformations can be supposed. The intercept term of the regression straight line was found to be equal to the deformation caused by pure shrinkage. In spite of cracks appearing at higher loading levels the linearity was not distorted. The results indicate that an exponential function including one retardation time can be applied in practical computation Of long-term deformations.
