Application of Yield Line Theory to Round Determinate Panels

摘要

The Round Determinate panel test has been found to provide reliable and economical post-crack performance assessment for Fibre Reinforced Concrete (FRC) and Shotcrete (FRS). However, it suffers the problem that performance parameters obtained from this test are difficult to relate to the in situ behaviour of FRS. This investigation has sought to improve understanding about the behaviour of FRS in structures by examining the relationship between post-crack behaviour in beams and corresponding performance in Round Determinate panels. Several types of FRS exhibiting post-crack strain softening have been studied using Yield Line theory to predict the load-deflection response of round determinate panels based on moment-crack rotation relationships developed from tests on beams.
