The results show that the effect of statistical uncertainty due to limited sample size on the estimated return period value of the wind speed and structural reliability is largely reduced if the sample size is increased from 10 to 20. The influence of this uncertainty on the estimated return period values of annual maximum wind speed and structural reliability is quantified in this study. You agree that you bear sole responsibility for your own decisions to download or use any of the software listed.The small sample size of the annual maximum wind speed at a wind speed recording site causes uncertainty in the estimated return period of wind speed. It assesses the critical stresses associated to the elastic buckling of plates loaded in their plan.Īll downloadable or viewable content available on is provided as-is. Merely move the mouse pointer to the desired cell to view the contents of that particular comment box.). Note: presence of a comment box is denoted by a red triangle in the upper right-hand corner of a cell. Note: a version of this document applicable to the ASCE 7-05 Code was not available.) 11. This program uses the equations listed in the reference, Guide to the Use of the Wind Load Provisions of ASCE 7-02 for determining the external wind pressure coefficients, GCp, used in the Wall CC and Roof CC worksheets. This can be utilized for open process-type structures as well as pipeutility racks and bridges. Worksheet for Open Structures is applicable for open structures without roofs up to 500 feet tall. Worksheet for Stacks Tanks is applicable for cantilevered structures up to 600 feet tall.

Worksheets for Wall CC and Roof CC are applicable for flat roof buildings, gable roof buildings with roof angles 8. For flexible buildings or structures, this program calculates the gust effect factor, Gf, per Section 6.5.8.2 of the Code based on the assumed formula for the fundamental period of vibration from Section 12.8.2.1 of the Code, where the exponent x in the formula T Cthx is assumed to be 0.75.
