Development of Smart Target Design Assist Toolkit (STDAT)

The Air Force (AF) is in need of an auto-designer tool that can be applied to verify the design adequacy of both baseline and modified target structures for weaponeering applications. The desired approach would allow for the auto-designer tool to apply structural engineering calculations to verify that structural components are adequately sized. Any alterations to the structure size, column spacing, wall span, etc. would result in a change to the structural component sizing. Additionally, the AF would like the result of the effort to be a software tool that is tied into AFRL’s Endgame Framework, for use in existing weaponeering tools. In Phase I, a framework for a novel auto-designer tool - The Smart Target Design Assist Toolkit (STDAT) - was developed. The core programmatic architecture of STDAT was created in Python and designed to interface with Smart Target Model Generator (STMG) metadata. STDAT offers a powerful, yet expedient multi-degree-of-freedom linear and nonlinear structural analysis and design capability that can be leveraged for 15-minute weaponeering cycles and longer duration special studies. Feasibility of the STDAT framework was demonstrated for the reinforced concrete framed light office building construction type. Two case studies were evaluated: a rectangular and non-rectangular multi-story, multi-bay building model generated in STMG and subjected to a multi-column removal scenario to represent model modifications for a first-story lobby space. For both case studies, STDAT was used to automatically analyze and re-design the modified building model in less than 30 seconds. This Phase II effort aims to expand the STDAT framework, both in terms of new capability and construction types, and execute a phased integration approach into the Endgame Framework (EF) platform. A "smart" structural design process will couple both existing/improved STMG rule bases and newly developed structural design functions with a design optimization algorithm that will afford the user with control over how and where the building design is optimized. The STDAT framework will be enhanced to handle generalized lateral load analysis (seismic and wind) and expanded to include three (3) additional construction types: reinforced concrete framed high-rise construction, steel framed construction, and masonry construction. A phased approach will then be taken to fully integrate STDAT into EF. Custom STMG/STDAT import and export utilities will first be developed, to facilitate EF compatibility testing, external module testing, and to offer an STDAT standalone usage mode. Once EF compatibility testing is complete, custom STDAT plug-ins will then be developed to permit direct interrogation of EF metadata and a fully automated usage mode within the EF platform.
