5 Shear Reinforcement Notation Notation R HR VR U L H D VL HL Table A5: Shear Reinforcement Notation Description Peripheral Rectangular Tie Horizontal rectangular tie (greater dimension of tie along smaller dimension of specimen) Vertical rectangular tie (greater dimension of tie along greater dimension of specimen) U-Loop Link Hair pin tie Diamond shaped tie Vertical Link (along greater dimension) Horizontal Link (along smaller dimension) Example of entry in the Shear Reinforcement Type in the database: 1R1H implies a combination of 1 rectangular tie & 1 hair pin tie 2R implies a combination of 2 rectangular ties Figure A 4: Typical shear reinforcement & notation used in database RC Database Notation 5

6 Longitudinal Reinforcement Anchorage Table A6: Longitudinal Reinforcement Anchorage Notation Description H Longitudinal reinforcement has been anchored by hooks (180 0 ) W Longitudinal reinforcement has been anchored by welding the bars into a metal plate DE Test configuration is Double Ended, so the anchorage length is infinite SH Simply supported section with hooked anchorage H 90 Longitudinal reinforcement has been anchored by hooks (90 0 ) CH Corner bars hooked at 90 0, intermediate bars not hooked Anchorage type H: Bars hooked with at Anchorage type CH: Corner bars hooked at 90 0, intermediate bars not hooked Figure A 5: Hooked Anchorage showing the length indicated in the database RC Database Notation 6
