3 cards from this section. Quick, good the night before a test.
What defines a plastic hinge?
Think about where a beam might start to yield.
What is the formula for nominal strength in a compact section?
Remember, it involves plastic section modulus and yield strength.
What is the nominal moment strength formula for compact sections?
Remember the components involved in the equation.
True or False: All sections can be classified as either compact or partially compact.
Think about how beam categories help in design.
A steel beam is designed with a width of 12 inches and a thickness of 0.5 inches. Determine if it qualifies as compact based on the width-to-thickness ratio for flanges.
Always reference the given formulas for critical ratios.
A beam experiences a load causing a moment of 5000 in-lbs. Calculate the necessary plastic section modulus given that the yield strength is 36 ksi.
Use units correctly to ensure accurate calculations.
