A command-structured, problem-oriented language designed for the computer estimation of wind action on structures is introduced. The language, named wasp (for wind action on structures, problem-oriented language), provides all resources for the engineering professional to assess the effects of wind on structures, particularly bridge decks. It allows an easy, speedy way t o evaluate the performance of structures under wind loads, especially for cases not covered by existing codes and a preliminary definition of geometry for further wind-tunnel tests.

The command structure is flexible and user-friendly. All design parameters can be readily obtained, such as wind forces and shape factors. Extensive graphical possibilities are incorporated, including forces, velocity and pressure fields and contour plots.

The processing unit relies on the finite element method, giving accurate results that compete with the corresponding experimental counterparts. It is finally argued that reliable numerical methods, state-of-the-art software and equipment may gradually substitute traditional experimental tests, in analogy with other areas of structural engineering.
