- If you could help me answer these questions in matlab that would be great, I provided an additional picture detailing what the outcome should look like.arrow_forwardA fully grouted reinforced masonry wall is to be constructed of 8-in. CMU. The wall height is 18feet. It is assumed to be simply supported. The wall is to be designed for an out-of-plane seismicload of 52 lbs./ft.2, which can act in either direction. The wall also supports a roof dead load of600 lbs./ft. and a roof live load of 300 lbs./ft. along the wall length. The roof loads have aneccentricity of 2.5 inches. Since there is seismic load, load combinations (6) and (7) in Chapter 2of ASCE 7-22 should be considered. In these two load combinations,horizontal seismic loadhE =andvertical seismic loadvE = . You may ignorevE in this problem for simplicity. The masonryhas a specified compressive strength of 2,500 psi. (a) Use the strength design provisions of TMS402 to determine the size and spacing of the vertical bars needed. Use the P-δ analysis method inSection 9.3.4.4.2 of TMS 402 to determine Mu. (b) Repeat the design using the momentmagnification method in Section 9.3.4.4.3 instead.arrow_forwardThe factor of safety for tipping of the concrete dam is defined as the ratio of the stabilizing moment due to the dam's weight divided by the overturning moment about OO due to the water pressure (Figure 1).

The values of the parameters are: • • maximum trip completion rate gmax=100 [veh/min] critical accumulations ncr1=1000 [veh] and ncr2=1500 [veh] jam accumulation njam=4000 [veh]. gmax ncr1 ncr2 njam There are two types of demands in the morning peak hour (7-8am): trips generated from outside the city center with rate q1=80 [veh/min], and trips generated from within the city center with rate q2=50 [veh/min].

Assume the arrival and service processes are stochastic. Using any software (Excel, Matlab, or the one you prefer), plot average delay time (including service time) and average queue size (including the vehicle currently being served) for all combinations of λ = {1,2,3,..,10} and p = {0.1,0.3,0.5,0.7,0.9}. Specifically, we ask you to make 2 graphs (one for average delay and the other for average queue size), where the x-axes contains the different values for 1, and where you make one curve for each p. b. Assume the arrival process is stochastic but the service process is deterministic with rate μ.

- A traffic signal has a 60-second cycle length (Red time + Green time). For the travel direction of interest, the red and green times are 30 seconds each, the arrival rate is constant at 20 [veh/min] and the saturation flow (i.e., the departure rate) is 1 [veh/sec]. a. Calculate the average delay (for all vehicles) for the travel direction of interest. b. Assume a work zone on the street downstream of the intersection so that only 25 [veh/min] (in the direction of interest) can pass. Calculate the average delay caused by the work zone to a vehicle leaving the intersection. Assume that the queue at the work zone never backs- up into the intersection. c.
