ASCE/SEI 7-22由ASCE结构工程研究所规范和标准活动部建筑和其他结构的最小设计荷载和相关标准委员会编制，为一般结构设计提供了最新和协调的荷载规定。本标准规定了所有危险的设计荷载，包括死荷载、活荷载、土壤荷载、洪水荷载、海啸荷载、雪荷载、雨荷载、大气冰荷载、地震荷载、风荷载和火灾荷载，以及如何评估荷载组合。2022年版ASCE 7取代了ASCE 7-16，与最新的结构材料标准相协调，包括ACI、AISC、AISI、AWC和TMS的标准。重大的技术变化包括:海啸和特殊负载的新目标可靠性表；土壤中水荷载的新替代方法；从护栏系统到防护系统的术语变化； 紧急车辆荷载的新规定；与州政府机构协调，更新夏威夷和加利福尼亚州许多人口稠密地区的海啸数据；地面水平管道的新海啸规定；修改地面雪荷载，以反映更近期的雪荷载数据和可靠性目标值；修正了估算漂移的方法，包括风参数；设计雨荷载修正，明确考虑积水头；美国大陆和阿拉斯加新的针对风险的大气冰负荷数据；无需Fa和Fv系数的多周期反应谱数据；新型抗侧力系统，如钢和混凝土耦合复合板剪力墙、钢筋混凝土延性耦合剪力墙、交叉叠层木剪力墙和混凝土桌面结构；刚性墙、柔性地下连续墙建筑（大型箱式商店/仓库）的新规定；支持和互联（耦合）非建筑结构的新规定和更新规定； 针对MWFRS和高架建筑C&C的新风规定；龙卷风条款的新章节；新的风和龙卷风长重现期危险图。除技术变更外，2022年版ASCE 7条款还附有详细的注释，以及为帮助本标准用户（包括设计从业者、建筑规范委员会和监管机构）而开发的解释和补充信息。标准ASCE/SEI 7是美国和全球建筑规范的一个组成部分，并通过引用被纳入国际建筑规范、国际现行建筑规范、国际住宅规范和NFPA 5000建筑施工和安全规范。结构工程师、建筑师和参与制定和管理当地建筑规范的人员将发现，结构荷载要求对他们的实践至关重要。

Prepared by the Minimum Design Loads and Associated Criteria for Buildings and Other Structures Standards Committee of the Codes and Standards Activity Division of the Structural Engineering Institute of ASCEMinimum Design Loads and Associated Criteria for Buildings and Other Structures, ASCE/SEI 7-22, provides the most up-to-date and coordinated loading provisions for general structural design. This standard prescribes design loads for all hazards including dead, live, soil, flood, tsunami, snow, rain, atmospheric ice, seismic, wind, and fire, as well as how to evaluate load combinations. The 2022 edition of ASCE 7, which supersedes ASCE 7-16, coordinates with the most current structural material standards including those from ACI, AISC, AISI, AWC, and TMS.Significant technical changes include the following: new target reliability tables for tsunami and extraordinary loads; new alternative method for loads from water in soil; terminology change from guardrail system to guard system; new provisions for emergency vehicle loads; updated tsunami data for Hawaii and many populous locations in California, coordinated with the state agencies; new tsunami provisions for above-ground horizontal pipelines; revised ground snow loads to reflect more recent snow load data and reliability-targeted values; revised method for estimating drifts to include a wind parameter; design rain load revisions to explicitly consider a ponding head; new risk-targeted atmospheric ice load data for the continental United States and Alaska; multi-period response spectrum data that eliminates need for Fa and Fv coefficients; new lateral force resisting systems such as steel and concrete coupled composite plate shear walls, reinforced concrete ductile coupled shear walls, cross-laminated timber shear walls, and concrete tabletop structures; new provisions for rigid wall, flexible diaphragm buildings (big box stores/warehouses); new and updated provisions for supported and interconnected (coupled) nonbuilding structures; new wind provisions for MWFRS and C&C of elevated buildings; new chapter of tornado provisions; new long return period hazard maps for wind and tornado.In addition to the technical changes, the 2022 edition of ASCE 7 provisions are accompanied by detailed commentary with explanatory and supplementary information developed to assist users of the standard, including design practitioners, building code committees, and regulatory authorities.Standard ASCE/SEI 7 is an integral part of building codes in the United States and around the globe, and is adopted by reference into the International Building Code, International Existing Building Code, International Residential Code, and NFPA 5000 Building Construction and Safety Code. Structural engineers, architects, and those engaged in preparing and administering local building codes will find the structural load requirements essential to their practice.
