Use the MWFRS Envelоpe Prоcedure in ASCE 7-10 Chаpter 28, Pаrt 1 tо аnswer this question. Assume that the building meets the conditions described therein. You have been tasked with designing a partially-enclosed building. The mean roof height is 15 ft, and the roof angle is 30 degrees. The basic wind speed provided by the local building authority is 140 mph. Assume that exposure category C is applicable and that the building is not located on a hill or an escarpment. Determine the MWFRS design wind pressure, p, on Zone 2 using the negative value of GCpi for Load Case A. Disregard the minimum pressure of 16 psf described in section 28.4.4.

We аre gоing tо run а Mоnte Cаrlo PRA (probabilistic risk analysis) simulation of the risks of bombs being set off on passenger busses. This is similar to the Compressed Natural Gas case study from Week 6 and you are encouraged to use your materials from that case study here.This is not a SIPmath problem. This is a plain-vanilla Excel Monte Carlo simulation problem.1. You have a passenger bus system.2. Every so often, an Initiating event occurs. For the purposes of this problem, assume that the Initiating event has already occurred – i.e., a terrorist has already left a bomb somewhere in our passenger bus system.3. The first event which happens after the Initiating event is whether or not it is raining. It will be raining with a probability of 25% and not raining with probability 75%.4. The next event which happens after the weather event is whether the bomb is discovered by a bystander or not. The probability of discovery is independent of the weather. Each bomb has a 40% chance of being discovered and a 60% chance of being not discovered.5. Now, depending on the weather and discovery situation, we have an explosion with varying probabilities. Probability(bomb goes off) Discovered Not Discovered Raining 0.1 0.6 Not Raining 0.5 0.9 The probabilities are given in this table. You can see if we have a bomb Discovered during rain, we have a 10% chance it will actually go off (because they will quickly call the bomb squad and it will be soggy anyways.) If we have a bomb Not Discovered and Not Raining, there is a 90% chance of it going off.6. Consequences. For the purposes of this exam, we are going to assume that anytime there is a bomb, it results in the fatalities of everybody on the bus. We know that the bus has the following states:a. driver only on board, 50% of the time, 1 fatalityb. a few people on board, 40% of the time, 5 fatalitiesc. full bus, 10% of the time, 50 fatalities.For the purposes of this problem, assume the weather and the discovery probabilities are independent of the number of people on the bus - i.e. there are no more or less likely to be full busses when it rains.Construct a Monte Carlo simulation of this risk assessment. Run it for 5000 trials. You should be using RAND() to simulate random variables, and you will probably want to use VLOOKUP and/or INDEX to get your probabilities in there. You are encouraged to use existing homeworks as a template for your answer if you feel they will be useful.In your simulation, set up answers for the following questions:1. What percentage of your total risk comes from rainy days?2. What percentage of your total risk comes from Not Discovered bombs?3. A full bus occurs only 10% of the time. What percentage of your total risk comes from a full bus?Attach your spreadsheet here. Name it XXXX-Final.xlsx where XXXX is your name.
