Question 2 (1 point)

In an area prone to earthquakes, a civil engineer should design the modern one- and two-story wood-frame houses to be able to move up and down, and sideways without failing. The ability to withstand earth movements is given by building shear walls and by using bracing and other elements that tie the walls, foundation, and roof together.

Question 3 (1 point)

In an area prone to earthquakes, a civil engineer should design a house to resist seismic waves, bearing in mind the following rules: Bolt it. Bracket it. Brace it. Block it. Panel it.

Q2. What elements of OSHA guidelines on workplace violence can be adapted for use in construction companies? Enlist and explain those elements?

A traffic signal has a 60-second cycle length. For the travel direction of interest, the effective red and green times are 30 seconds each, the arrival rate is constant at 20 vehs/min and the saturation flow (i.e., the queue discharge rate) is 1 veh/sec.

a. Calculate the average delay (in seconds) for the travel direction of interest

b. What is the maximum length of a queue (in vehicles)?

c. Assume that works on the street are taking place downstream of the intersection so that only 20 vehs/min (in the direction of interest) can pass. Calculate the average delay [sec] caused by the street work to a vehicle leaving the intersection. Assume that the queue at the downstream restriction never backs-up into the intersection.

1. You are tasked with creating the ultimate modular home that can allow a person to survive in extreme temperatures.  This house must be able to survive wintering in the Antarctic,  monsoon season in Vietnam, and summering in the Atacama Desert. Due to the inhospitable areas this home model can be located, it must be able to function off-grid.

2. You've been stranded in the Salt Flats of Utah.  As you create your own make-shift shelter, what passive solar elements will you try to implement in your temporary home?

1-The following list of readings were taken in sequence during a levelling survey:

Readings (m):    1.163, 2.592, 3.616, 0.778, 2.348, 1.838, 2.469, 1.666, 2.893, 1.594   

The level instrument was moved after the fifth and eighth readings.

Required:

(i) Fill in the leveling table and find the RLs of all points.

(RL of the first observed point = 105.00m). Use R & F method and check using HCI method. Apply arithmetic check in both cases.

*Please solve it by detail.

a) Explain with an illustration why only external pressures are considered when determining the primary (i.e. global) structural action due to wind loads.

b) What range of Cpi would you consider for a residential apartment building?

c) Which exposure classification would apply for the following situations:

a. Wind coming from Lake Ontario for a building located on the waterfront in Toronto.

b. A tourism center located in a national park in Northern Ontario.

c. A structure located on the edge of an urban area with a few homes between it and farmland.

d. A storage unit for a construction company located in a rural community without many trees.

d) What conditions must be satisfied for the equivalent lateral force procedure to apply?

Answer all of this, if not please answer some of it. Thanks

What happens with the degradation of substrates in activated sludge if you add a clarifier. The activated sludge retention time is 0.5 days and the sludge age is 2 days. Also, what if the sludge age is 4 days

1. A surveyor completes a levelling circuit from a known BM at point A (RL = 37.730 m). At the end of the survey, the surveyor finds out that the rod person moved the graduated staff before a BS value was taken at the third change point. The levels obtained are as follows:  

1.857 (RL = 37.567 m), (0.983, 0.354), 0.571, 1.011, 2.151, (1.124, x), 0.890, (0.543, 3.178), 3.808.  

1. Assuming that the misclosure for the level circuit is 0.000 m, find the probable value of the missing BS value x.   
2. Is the value of x in part (a) acceptable? Explain. (1 mark)

Book the levels, including the value of x calculated in part (a) using the HPC method and show all arithmetic checks. (1 mark

1. To Research for NDT cases online. To find one case where magnetic particle testing was used and one where liquid penetrant was used.
2. To discuss why we think each method is more appropriate for each case
