"ASCE710W" --- ASCE 7-10 CODE WIND ANALYSIS PROGRAM

Program Descripio!

"ASCE710W" is a spreadsheet program written in MS-Excel for the purpose of wind loading analsis for !uildings

and structures per the ASCE 7-10 Code Specificall# wind pressure coefficients and related and re$uired

parameters are selected or calculated in order to compute the net design wind pressures

%his program is a wor&!oo& consisting of se'en (7) wor&sheets# descri!ed as follows*

Wor#s$ee Name Descripio!
