This paper reviews the design development of a 985' high free-standing communications tower recently constructed in San Francisco. Included is a description of the structural configuration of the
 tower and the criteria by which it was designed. The dynamic characteristics of a three-dimensional linear elastic mathematical computer model, devised to represent the physical structure, are presented. The dynamic response of this computer model to various levels of
ground shaking, including both horizontal and vertical excitations,
 are summarized, evaluated and compared to the seismic force levels prescribed by the 1969 edition of the San Francisco Building Code.
 Also included in the comparison are the responses derived for the tower from wind tunnel studies and static wind design criteria.

The paper reports on the application of an existing three-dimensional computer code to the calculation of the flow and temperature field past cooling towers. The code uses a rectangular grid so that the round tower geometry has be approximated by steps. Simulations are presented of various idealized laboratory studies carried out with cylindrical cooling tower models with the ratio of plume exit to cross-wind velocity varying in the range 0.2 to 1.7 and the densimetric Froude number in the range ∞ to 2. By comparison with the experimental results it is shown that the computer model is capable of reproducing the main features of the complex flow and temperature field past cooling towers including the downwash effect at strong cross winds. The quantitative agreement is not always entirely satisfactory, and suggestions are made for improving the computer model.
