The program calculates the appropriate wind loads and presents the calculations in a printable report. Part 2 of this Digest demonstrates the calculation procedure for determining wind loads and includes example calculations for a two-storey house and a 120 m residential tower on a two-storey (8 m) podium. Various examples illustrate different methods of obtaining wind loads given in the Standard. •Wind Load Provisions for Buildings Definitions and terms used in all Procedures Alternative Procedures of Analysis –Simplified –Analytical (Low rise or high rise) –Wind Tunnel •Examples of calculation of horizontal wind pressures •Cylindrical Structures 5. It is not unusual for road pavements to get progressively thicker over a number of years as each new surfacing is simply laid on top of the one before it. The structural calculations included here are for.
