"ASCE705W" --- ASCE 7-05 CODE WIND ANALYSIS PROGRAM Program Description: "ASCE705W" is a spreadsheet program written in MS-Excel for the purpose of wind loading ana and structures per the ASCE 7-05 Code. Specifically, wind pressure coefficients and relate parameters are selected or calculated in order to compute the net design wind pressures. This program is a workbook consisting of nine (9) worksheets, described as follows: Worksheet Name Description Doc This documentation sheet Simplified Analysis using simplified method for low-rise buildings with h MWFRS (Low-Rise) Main Wind-Force Resisting System for low-rise buildings with h MWFRS (Any Ht.)

Worksheet for "Simplified" analysis is applicable for low-rise buildings meeting the cr 2. In the worksheet for Simplified analysis, the design MWFRS wind load is calculated for The design MWFRS load is assumed to be the total wind load on either the width or the building respectively. 3. Worksheet for "MWFRS (Low-Rise)" is applicable for low-rise buildings as defined in Sec 4. Worksheets for "MWFRS (Any Ht.)", "Wall C&C", and "Roof C&C" are applicable for buildin heights of up to 500 feet. 5. In worksheets for "MWFRS (Any Ht.)", "Wall C&C", and "Roof C&C" the user may opt to uti steps in height, 'z', in determining the wind pressure distribution. 6. Worksheets for "MWFRS (Any Ht.)", "Stacks & Tanks", and "Open Structures" can handle “r “flexible” buildings and structures. For “rigid” buildings or structures, this progra either 0.85 or the calculated value from Section 6.5.8.1 of the Code for the gust effe buildings or structures, this program calculates the gust effect factor, ‘Gf’, per Sec based on the assumed formula for the fundamental period of vibration from Section 12.8 where the exponent 'x' in the formula T = Ct*h^x is assumed to be 0.75. 7. Worksheets for "Wall C&C" and "Roof C&C" are applicable for flat roof buildings, gable roof angles <= 45 degrees, and monoslope roof buildings with roof angles <= 3 degrees. 8. Worksheet for "Stacks & Tanks" is applicable for cantilevered structures up to 600 feet 9. Worksheet for "Open Structures" is applicable for open structures without roofs up to 5 tall. This can be utilized for open process-type structures as well as pipe/utility r 10. This program uses the equations listed in the reference, “Guide to the Use of the Wind ASCE 7-02” for determining the external wind pressure coefficients, ‘GCp’, used in the C&C worksheets. (Note: a version of this document applicable to the ASCE 7-05 Code wa 11. This program contains numerous “comment boxes” which contain a wide variety of informat explanations of input or output items, equations used, data tables, etc. (Note: pres is denoted by a “red triangle” in the upper right-hand corner of a cell. Merely move desired cell to view the contents of that particular "comment box".)
