4) Find the most economical wide flange section for an A992 steel beam (E = 29 x 10³ ksi) using LRFD which spans 45 ft. with a dead load of 50 lb/ft² and a live load of 95 lb/ft² if the beams are spaced 12 ft apart and full lateral bracing is provided. Determine the total maximum deflection. (Because the beam is fully braced, you should utilize a reference table with wide flanges in descending order of Z as found in the note set.) Additional wide flange properties which the text does not show text is provided on the following pages %3D
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
