(10 pts) According to counts taken 3 years ago that are available on the ADOT’s website, SR441 had an AADT value of 17,140 in downtown Tucson. While waiting for PAG or ADOT to retrieve the hourly traffic counts for SR441 from its archives, the city engineers decided to use the Florida default values to begin his analysis. A short time later, the requested data - the peak hourly volume was 1779. (a) What K-factor should the city engineer have used in his preliminary analysis while waiting for hte state’s data? What is the resulting peak volume? (b) What K-factor did thesegment of SR441 acctually have, according to the state’s data? (c) What is the impact of using the Florida data? Typical K-Factor for Florida Roads Typical K-Factors for Florida Roads Area Types K-Factor Urban 0.093 Transitioning/Urban 0.093 Rural Developed 0.095 Rural Undeveloped 0.100

  1. A one-way slab has been designed for a simply supported span of 4.0 m with an overall depth of 170 mm and clear cover of 20 mm, using M 20 concrete and Fe 415 steel. The dead loads are taken as 5.0 kN/m2 and the live loads as 2.0 kN/m2. The longitudinal bars are designed as 10 mm φ @ 150 c/c. Verify the adequacy of the thickness provided,
  1. Applying the limiting span/effective depth ratio;
  2. Actual calculation of total deflections.

Considering a vertical sluice gate in a horizontal smooth rectangular channel, the upstream and downstream water depths are 5.1 and 0.45 m, respectively. The upstream flow velocity is 0.5 m/s and the channel width is 27 m. Calculate the downstream flow depth and the force acting on the sluice gate. Draw the control volume and show the forces acting on the sluice gate.

A doubly drained specimen, 2.54 cm in height, is consolidated in the lab under an applied stress. The time for 50% overall (or average) consolidation is 12 min.

(a) Compute the cv value for the lab specimen.

(b) How long will it take for the specimen to consolidate to an average consolidation of 50%?

(c) If the final consolidation settlement of the specimen is expected to be 0.43 cm, how long will it take for 0.18 cm of settlement to occur?

(d) After 14 minutes, what percent consolidation has occurred at the middle of the specimen?

Determine the reactions at the support of the beam. Shear force and bending moment for the beam are described by V(x)= c0 + c1x + c2x2 and M(x)= k0 + k1x + k2x2 + k3x3, respectively. Calculate the coefficients for the shear force and bending moment equations. Use L = 5.8 m, q = 2.7 N/m, and w = 8.6 N/m for your calculation.

Also, determine

Vertical reaction force at A in N (upwards force is positive, round your result to 1 decimal place)

Reaction moment at A in Nm (clockwise moment is positive, round your result to 1 decimal place)

Location of the maximum shear force in the beam in m (round your result to 1 decimal place)

Maximum shear force in the beam in N (round your result to 1 decimal place)

1) Describe how you can use measurements of stream height (stage) to estimate discharge and what pieces you need to do so. (I’m looking for you to describe both the curve and one method for making discharge measurements)

2) If a flood occurs and erodes the channel where we are measuring stage, can we still use the same relationship between stage and discharge? Why or why not?
