ASCE 7-05 equation (6-13a) for gust effect on flexible structures

[bjcure]

Does anyone know what the little "e" is in this equation?
Thanks.

Euler's constant:

should be in your calculator.

Not Euler's Constant...that has a value of 0.57....

e is the exponential function or the inverse of a natural logarithm. It has a value of 2.72.

Ron - yup, wrong word, correct link -

Just to be clear, e is the base of natural logarithms. It is numerically equivalent to the limit of (1 + h)^1/h as h approaches zero.

FYI it is still called Euler's number (just Euler's constant which as Ron noted is different):

WillisV,

You are absolutely correct! I was not aware that 'e' was named after Mr. Euler. I'll be darned. That is very interesting.

Got it! Thanks for the comments!
