CMCE 2416 Elements of Structural Design - New York City College of Technology
Assignment: T-Beam Design as a part of floor system
Purpose: To apply techniques learned to the design of a concrete T-Beam for moment.
Directions:The proposed building is a two-story commercial office building. At this stage as an engineer, you should design a one-way slab as a part of floor system at roof for just one span, according the information provided in the following:
Design Criteria:• Roof area is 60'x80'.• In 60' direction, there are 4 columns, which have divided the width of the roof to 3 equal spans.• In 80' direction, there is just one span (No column in between).• Concrete construction is normal weight concrete with f'c = 4000 psi.• Reinforcing steel is new and conforming to ASTM A615 grade 60 (fy=60,000 psi).• Assume that each span is separate from others, and simply supported.• Design moment for each T-beam is obtained using the design distributed load (wu) for each t-beam span (S=9.875 ft) Figure (3)• You can ignore the width of columns, in order to find the L of span.• Roof Loads: 100 lb/ft2 dead load, 125 lb/ft2 service live load. Include weight of the slab as a dead load in design for moment.

please solve for everything asked on the assigment sheet. also(redesign the slab, find and consider self weight of the t-beam and edge beam.) show step by step calculation and digrams. use US units.
If the weight flowrate into the elbow is 47 lbf/s, find the mass flowrate out of the elbow, the volume flowrate in and out of the elbow, and the average velocity in and out of the elbow.
On a single graph, plot the PDFs if E is assumed to be normally, lognormally, and gamma distributed. Plot the PDFs for E values between 10,000 and 50,000 kips/in2. Make sure to label the axes and use a legend to label the curves.
find an expression for the diameter, D, of the droplet, in terms of the specific weight and surface tension, assuming the contact angle just before seperating is zero.
Briefly explain the difference between piezometer and tensiometer with respect to the working principle, special design consideration and limitation of the instrument.
Build a scale model of the house project showing the main structural and non-structural materials, services and built in furniture as covered by this subject.
A 200 3 Computer Problems 250-mm panel of mass 20 kg is supported by hinges along edge AB. Cable CDE is attached to the panel at C, passes over a small pulley at D, and supports a cylinder of mass m.
