Report Title : Enhanced Technical Guidelines for Design of Debris-resisting Barriers (2018), 34 p.

Author : J.S.H. Kwan & R.C.H. Koo


Improved guidelines for design of rigid and flexible debris-resisting barriers are proposed. It is recommended that variation of debris velocity at the location of a barrier can be taken into account for determining the design debris velocity with the consideration of multiple phases of impact on the barrier. In addition, design considerations for estimating the retention volume for the design of barriers are also recommended.
