An office building is planned with a lateral-force-resisting system designed for earthquake resistance in aseismic zone. The seismic capacity of the proposed system, expressed as a force factor, is assumed tofollow a lognormal distribution with a median of 6.5 and a standard deviation of 1.5. The ground motionfrom the largest expected earthquake at the site is estimated to correspond to an equivalent force factor of 5.5.(a) What is the estimated probability that the building will experience damage when subjected to the largest expected earthquake?
(b) If the building survives (i.e., experiences no damage) during a previous moderate earthquake with aforce factor of 4.0, what is the updated probability of failure of the building under the largest expectedearthquake?(c) Suppose future occurrences of the largest expected earthquake follow a Poisson process with a mean return period of 500 years. Assuming that damage events from different earthquakes are statisticallyindependent,…
During a plant visit, it was noticed that a 12-m-long section of a 10-cm-diameter steam pipe is completely
exposed to the ambient air. The temperature measurements indicate that the average temperature of the
outer surface of the steam pipe is 75°C when the ambient temperature is 5°C. There are also light winds in
the area at 10 km/h. The emissivity of the outer surface of the pipe is 0.8, and the average temperature of
the surfaces surrounding the pipe, including the sky, is estimated to be 0°C. Determine the amount of heat
lost from the steam during a 10-h-long work day.
Steam is supplied by a gas-fired steam generator that has an efficiency of 80 percent, and the plant pays
$1.05/therm of natural gas. If the pipe is insulated and 90 percent of the heat loss is saved, determine the
amount of money this facility will save a year as a result of insulating the steam pipes. Assume the plant
operates every day of the year for 10 h. State your assumptions.
