4.0 Building HeightBuilding height is used in the calculation of angular distortion and represents theheight of the element for which damage predictions are calculated. In somecases, portions of the buildings are evaluated separately to identify the worst caseangular distortion value.Table D-3. Building HeightWall ConditionHeight Assumption1. Building superstructure only H = building height above grade2. Building basement only H = foundation height to grade3. Low rise or separate area H = height as appropriate4. Areaway H = areaway height onlyAs can be seen in Figure D-8 when H/L≥0.5 there is nearly no impact upon theresulting calculation of β. Furthermore a greater damage state is predicted withsmall H/L, thus a small value of H provides a conservative prediction of damagestate.The Alaskan Way Viaduct & Seawall Replacement Program March 2010Proposed SR 99 Bored Tunnel - Assessment of Settlement Impacts to Buildings D-13Public Disclosure Request 11-0123 for Elizabeth Campbell - 2nd installment
