Example Problems

The example problem solutions for this chapter are found in the spreadsheet that can be obtained by clicking on the link below. The problems deal with analyzing or selecting members based on shear, flexure, deflection, local web yielding, and web crippling.  In addition are problems that look specifically at the design of cover plates and bearing plates.

Chapter 8: Excel Spreadsheet Solutions

Example Problem 8.1:  The intent of this problem is to see the effect of different laterally unsupported lengths on the capacity of a beam. The problem considers shear, flexure, and deflection. Take some time to look at how each limit state changes with unsupported length. You can experiment by changing member size and span length.

Example Problem 8.2: This problem is essentially the same problem as Example Problem 8.1 except the beam supports a uniformly distributed load instead of point load. The intent of this problem is to illustrate how different loading scenarios affect flexural strength.

Example Problem 8.3: This problem selects floor joists to span a given distance. This is a common problem in structural building design. The objective is to select the beam size and spacing that results in the lowest weight per square foot of floor area.

Example Problem 8.4: This problem illustrates the design of a typical floor beam in the dormitory building, including computing the loading applied to the beam. The problem also looks at various section types as alternatives for the beam, including I shapes, rectangular HSS and channels.

Example Problem 8.5: This problem illustrates the design of a typical continuous beam that uses cover plates to increase beam strength in locations of negative moment.

Example Problem 8.6: This problem illustrates the design of bearing plates. Both an interior and an end application are considered.
