Assignment #7: Analyze the 10-story structure of Assignment #5 under gravity, wind, and seismic loads. The analysis can be done using any structural program such as Sap, Etabs, or another program of your choice capable of performing analysis, including modal (spectral) analysis. The details of the building to be analyzed are given in Assignment #5. For wind analysis assume urban terrain. For your steel framing use the following sections. Floor Section Beams - 1st Floor 10th Floor W14x38 - 1st Floor 5th Floor W24x117 Columns - 6th Floor 10th Floor W24x76 Any information not given can be assumed for the buildings. You can assume your floor diaphragms are rigid in plane and can distribute the forces accordingly. The final deliverable results are the structural model of the building as well as a written report. The results of the project should be summarized in the report. You should perform the following tasks: 1. Perform modal analysis. Report the first 15 modal periods and modal mass participation factors. How many modes are required to describe the building response? 2. Analyze the building under the following loading scenarios. Practically, apply the relevant loads for each case and use the right load combinations: 2.1. Under gravity load combinations only 2.2. Under gravity and wind load combinations. 2.3. Under gravity and seismic load combinations. i. Using Equivalent Lateral Force procedure (ELF) ii. Using Modal Response Spectrum analysis For ELF and wind loading scenarios, apply the floor forces that you have hand calculated in Assignments #5 and #6 to your model to review the building response. For Modal Response Spectrum analysis, apply the seismic force using the Response Spectrum function of the software. For your results, include: • • . List of project information and relevant analysis information – short description. Diagram of seismic story shear and bending through the height of the building (two methods, one equivalent lateral force method, one the spectral analysis results from computer model). Comparison of story shears and overturning moment from wind and seismic forces (both ELF and Modal Response Spectrum). Use appropriate load factor per code for wind and seismic loads. Pay special attention to using load factors for wind that are consistent with the return period used for wind according to the version of ASCE 7 that you are using.) ❖ Assignment to be submitted in electronic format. ❖ Report, and models of the building to be uploaded to courseworks. ❖ Note: In lieu of reading from the maps in the code, Wind and seismic information for your location can be obtained from https://hazards.atcouncil.org/. Note that you need to pick the seismic and wind data with the right return period/corresponding to the right version of the code. Pay particular attention to using load factors that are consistent with the wind return period.

1. A pump-around reflux is an internal reflux for a distillation column where the liquid is withdrawn from a lower tray, cooled in a heat exchanger resulting in heat recovery and then sent back to an upper tray thus reducing the amount of top reflux. In a given distillation tower, the pump-around reflux is withdrawn from the 20th tray and sent to a pump on the ground which is located 20 m below the 20th tray. The pump discharge is cooled in a heat exchanger, and then returned to the 16th tray at the tray level through a control valve. The pump discharge line (including equivalent length of all fittings, bends,etc.) is 50 m long. For a nominal flowrate of 120 m²/h, pressure drop in the cooler is 20 kPa. Assume turbulent flow conditions. Neglect suction line frictional pressure drop. Following information is available:Tray spacing: 0.5 m, Pressure drop per tray: 1 kPa, Discharge pipe diameter = 0.3 m and f (friction factor) = 0.04, Density of Liquid (assume that it is constant) = 800 kg/m³, Tower top pressure: 300 kPa, Pump curve for the pump-around reflux pump is given by: APрump(kPa)=300 – 5v^2 where v is flowrate in m³/min a. For a 50% scale up in the pump-around reflux flow, what would be the minimum discharge pressure of the pump (i.e., under the condition when the pressure drop inа.the control valve is zero)? b. What is the pressure drop in the control valve for the 50% scale up case?

A 100 ft steel tape standardized at 68 °F and supported throughout under a tension of 10 Ibs was found to be 100.2 ft long. The tape had a cross sectional area of 0.009 in? and a weight of 0.03 Ib/ft. The tape is used to measure a horizontal distance (AB) and the measured length comes out to be 300 ft. CALTRANS plans a new ramp to connect Nutwood with US57. The ramp starts from point A (on Nutwood) to C (on US57) wherein point C will be vertically above point B (a current point on Nutwood that will get buried by ramp). The must have a smooth 4% grade, thus the tape will be used fully supported. Determine the correct slope distance to be measured (i.e. length AC) if a pull of 15 Ibs is used and the temperature is 96 °F.
