Explanation of Solution

The three categories of information gathered are:

  1. Engineering:
  2. It includes topography, geology, climate, and traffic volumes.
  3. Social and Environmental:
  4. It includes land-use and zoning patterns.It also includes types of wildlife; location of recreational, historic and archeological sites and the possible effects of air, noise, and water pollution.
  5. Economy:
  6. It includes unit costs for construction and the trend of agricultural, commercial and industrial activities.

These data can be obtained from existing engineering reports, maps, aerial photographs and chartswhich are usually at one of the state agencies such as departments of transportation, agriculture, geology, hydrology and mining. The type and amount of data collected and examined depend on the type of highway being considered.

Conclusion:

Preliminary analysis of the data will suggest if any of the specific sites should be excluded from further consideration.

Assume that in earthquake-resistant design, the following relations take place: Y=ce, where Y is the ground motion intensity at the building site, X is the magnitude of an earthquake, and the constant c is related to the distance between the site and center of the earthquake. Assuming that X is exponentially distributed, fx (x)=ex with x 20 and >2, (a) Derive the PDF and CDF of Y, including the bounds, and sketch them. (b) Determine the median (i.e., 50%-fractile) and 90%-fractile (value of Y that has a probability of not being exceeded of 90%) of Y. (c) Determine the mean and variance of Y by using the PDF of Y derived under (a). (d) Determine the mean and variance of Y directly from the PDF of X.
