Redesign the dome in Example 12.4 on p. 417 for the case of added internal pressure p = 2 kP a. Use the carpet plots for E-glass-polyester.

Example 12.4

Design of a dome. Part I. Compute the stress resultants on the dome. The dome intended to cover communication equipment. A composite material is selected to avoid interference with the signals being transmitted. Housing antennas and other electronics under the roof saves on equipment costs because the electronics does not have to be built for outdoor exposure. The dome must withstand its own weight and the weight of fixtures hanging from it, snow load, and eventual live load of workers performing maintenance. The dome, in the shape of a spherical cap, has span s = 24 m and height h = 2.4 m (Figure 12.4).
