Abstract

The objective of the present study is to estimate the flexural behavior and stiffness of the developed synthetic resin permeable blocks. The frame and kits consisting of the synthetic resin blocks exhibited a linear load-displacement relationship up to the yield state of the block. The flexural strength of the synthetic resin blocks ranged between 7.3 and 6.6 MPa, which were 3.5 and 1.9 times higher than the minimum requirements of KS F 4419. From the strain compatibility, force equilibrium, and idealized curvature distributions along the permeable block length on the basis of the elasticity theorem, the flexural stiffness (K) of synthetic resin blocks was formulated and then compared with test results, The proposed formula was converted into design charts to straightforwardly determine the stiffness of synthetic resin blocks.
