如本文所示，更新后的UFC 4-023-03相对于初始版本进行了重大修订和改进，以满足DoD和GSA的要求。根据分析和实验数据，这些修改解决了Tie Force和Alternate Path方法的缺点，并使文档在技术上更加合理和严格。使用占用类别来确定设计要求的适用性和水平，应该向更广泛的受众开放GSA和DoD累进式坍塌设计要求的组合。更新后的UFC 4-023-03中概述的程序还将为规划的规定性方法提供实质性基础，这些方法是为基于共识的民用建筑设计规范制定的逐步减少倒塌方法的一部分。
As demonstrated in this paper, the updated UFC 4-023-03 has been significantly revised and improved relative to the initial version, to satisfy both DoD and GSA requirements. The modifications address shortcomings in the Tie Force and Alternate Path methods and result in a document that is more technically sound and rigorous, based on analysis and experimental data. The use of Occupancy Categories to determine applicability and level of design requirements should open the combined GSA and DoD progressive collapse design requirements to a wider audience. Procedures outlined in the updated UFC 4-023-03 will also provide a substantial basis for prescriptive methods planned as a part of progressive collapse mitigation approaches being developed for consensus-based, civilian building design codes.
