The river is 270 feet wide. Building footprint is a 60 feet by 300 feet rectangle. Floor to floor height is 16 feet. The bottom of the first floor must maintain a minimum clearance of 30 feet above the river. Since the river water flow speed during winter is very fast, your hydraulic consultant has recommended that no columns or any kind of structural support be put in the river. Develop a structural system for the hotel (both for gravity and lateral load resistance. Problem 2: You’re the project architect for a 450-ft diameter circular stadium. Other than the perimeter RC beari -_ walls, no interior vertical support is to be placed wi '3 the stadium. Conceive a structural . .. structure.

The basement of the house is 10 ft. below grade (to the bottom of the footing). Since the City Building Code doesn't allow new footings to surcharge existing basementwails and footings, you've decided to build the column footing at the same level as the existing footings next door. The soils report says unbraced out should be sloped at 2(H):1(V). Any excavation over 3 feet should be brace. (1) Describe how you’re going to instruct your contractor to excavate and build the footings 10 feet below grade. Draw sketches to show the construction sequence. (2) Verbally describe how the column load is transmitted through the spread footing into the soil. l lam“: wvik HM-lu )Avamthfigmtwlb fit— l algal ii that: [It c.l/ w ~l a'xjxig v Fan-fl University of Southern California !RCH 411 I School of Architecture Dr. Jeff Guh Homework 2: Due Th., Feb. 3, 2005 Given: 1. 23-story office building in Downtown San Francisco (199 Fremont Street, to be exact.) See attached plans and elevations. 2. The structural system is steel moment frame around the perimeter and steel braced frame around the elevator and utility core. 3. Typical floor to floor height is 18 ft at ground floor and 13 ft above. 4. Everything else is undecided. Describe what you would do to meet the fire resistive requirements with respect to: The exterior non-bearing walls (cladding) The roof and floor decks. The steel beams. The steel columns. . The interior partitions (permanent). 6. Elevator shaft enclosure. 7. Floor-ceiling assembly. U‘F‘P’Nr‘ Please include simple sketches of the assembly and a brief paragraph to explain your reasoning.

To make a profit on the investment, the minimum gross square footage of the building has to be 22,000 sq. ft. For now, you can assume the footprint of the building is rectangular. Being cost conscientious, your client demands that you carefully plan the building's layout and select a suitable type of construction to minimize the construction cost. Your local contractor has quoted you the following unit costs for the various types of construction: The contractor has also quoted a $3lsq. ft. unit cost for installing fire sprinklers. Given that the local zoning ordinance requires a 5 ft. setback from adjacent property lines and 20 ft. from the street property line, how will you locate the building on the lot to achieve the desired gross square footage? (Show plan dimensions, setback from the property lines and number of stories.) What will be your choice of the type of construction for this project to keep the construction cost at a minimum? What kind of construction materials will you be using for the structure? What will be the fire resistive requirements for the building? What's your estimated construction cost?
