## University of Wisconsin – Milwaukee Department of Civil & Environmental Engineering CE 571 Design of Reinforced Concrete Structures HW01-1 Project 1 Due: Thursday, September 10, 2015 Dear colleagues, TYZ International is an engineering firm based in Milwaukee, WI serving clients around the globe. TYZ International plans to relocate its headquarter to Menomonee Falls, WI. The multi-story structure covers approximately 64,000 square-feet, providing a “state-of-the-art” facility for the growing company. We are seeking design firms that can carry out the design of the reinforced concrete structure. As a pre-screening process, engineering firms who are interested in the job are asked to solve the following related problems. Our final decision will be made after ten rounds of evaluation in December. In the first round, we would like you to demonstrate your knowledge on the basics of reinforced concrete design and the structural analyses. Specifically, we would like you to determine the maximum moment and shear in a simple beam. You may need to use the concept of influence lines because part of the loads are live loads, for which the location can vary. In addition, we need to know your capability of analyzing complex structures such as a statically indeterminate structure. You may use any computer software or hand calculation. Finally, we would like you to calculate section properties of a reinforced concrete section, just before the beam cracks and after the beam cracks. Please show all your calculations and present your findings in written forms. Engineering firms may also team up to enter the competition. At this moment, we would like you to form a engineering team, and show us the team structure, which should include at least one chief engineer, who is in charge of organizing the effort and communication; a couple of design engineers, who will perform the structural design; and one review engineer, who will check the design and document the verification process. Engineering firms should submit their work independently. We welcome your questions in the process through email (jzhao@uwm.edu) or phone (414-248-8999). The design document should be submitted to Room E170 of EMS building no later than September 10, 2015. Late submittals will be disqualified. Please present your work in a professional letter with your work in the appendix. Thank you for your attention, and good luck with your work. Dr. Zhao, Vice president, TYZ International. University of Wisconsin – Milwaukee Department of Civil & Environmental Engineering CE 571 Design of Reinforced Concrete Structures HW01-2 1. Determine the maximum positive moment and shear that can be developed at point D in the beam shown below due to a concentrated moving load of 4000 lb, a uniform moving load of 300lb/ft, and a beam weight of 200lb/ft. 2. Draw the shear and bending moment diagram. You are encouraged to use a computer program. 3. Consider a simple rectangular beam (b x h) reinforced with steel reinforcement of As. Assume b = 12 in., h = 20 in., As = 3.0 in2 and fc ’ =4 ksi and fy = 60 ksi. a) Determine the centroid and moment of inertia, Ixx for an ideal beam (no cracks). b) Determine the moment of inertia, Ixx, of beam if the beam is cracked and tensile forces are in the steel only. 4. Report your term project group. Please specify a chief engineer, a couple of design engineers, and a review engineer.
