Book excerpt: Computer program TWDA (T-wall design/analysis) is a user-oriented conversationally interactive, modular time-sharing program system for computer-aided structural design of inverted-T retaining walls and floodwalls founded on earth or rock. Its essential characteristics include: (a) List-directed input with prompting available on request or as shown to be needed. Data lists may be entered interactively or in a data file. (b) Design for minimum cost including excavation, backfill, slab concrete, and stem concrete, with inputted unit costs. Default is to design for minimum concrete volume. (c) Multiple soils strata may be used as existing and/or backfill earth. Either Coulomb's equation or trail wedges may be used to get active earth pressures. (d) Multiple slopes may be used to model existing and/or finished grade surfaces. (e) Time-sharing printout is limited to the minimum needed by the user to make his design decisions. A full analysis report is available in an optional output file that may be listed on any terminal. (f) The program is structured to permit easy updating as criteria change. (g) Up to 10 load cases may be used. The user does not need to reenter any data by hand into subsequent runs. (h) The 1977 edition of ACI code 318 is used. Default procedures conform to the Corps of Engineers' Engineer Manuals in effect in 1980. The user may, however, direct the program to change many of the standard procedures as needed. (Author).
