GSA2003 美国联邦总务署 新联邦办公楼和重大现代化项目的连续倒塌分析和设计指南2003简介：

"GSA 2003"，全称为"General Services Administration's Design Guide for the Analysis and Design of Continuous Operations in New Federal Office Buildings and Major Rehabilitation Projects, 2003"，是由美国联邦总务署（General Services Administration，GSA）发布的指导性文件。该指南发布于2003年，主要针对的是美国联邦政府的新办公大楼建设和重大改造项目。

这份指南的核心目的是为了保障在联邦政府建筑中的持续运营，尤其是在灾难或紧急情况下，如地震、火灾等。它强调了建筑的结构安全、系统冗余、灾难恢复计划以及应急管理系统的设计，旨在确保政府机构在面对突发事件时仍能保持基本运营功能，减少中断时间和损失。

它涵盖了设计标准、建筑策略、建筑设备和系统的抗灾能力、以及如何进行风险评估和管理等多个方面，对提高联邦政府建筑的韧性、安全性和可持续性具有重要意义。它是美国公共建筑设计和建设的重要参考文件，也是政府建筑行业遵循的重要法规之一。

Structural design guidance,although not a requirement of these Guidelines,is provided for consideration duringthe initial structural designphase and prior to performingtheprogressivecollapseanalysisoutlinedinSection4.1.2tominimizethe mpactonthebuilding's final design.These Guidelines should actas a supplement to he Interagency SecurityCommittee(ISC)SecurityDesignCriteriaforNewFederal Office Buildings and MajorModernization Projects,which states that mitigation of progressive collapsebeaddressed in thedesign ofnew structures.

4.1.2Analysis

The following static linear elastic analysis approach may be used to assess the potential for progressive collapse in all newly constructed facilities.Other analysis approachesmayalsobeused,suchasthosediscussed inSection2.3,buttheanalysis considerations (Section 4.1.2.3) and allowable extents of collapse (Section 4.1.2.4), mustbeusedintheassessmentofthepotentialforprogressivecollapse.
