Use of IBC Design Maps The Maximum Considered Earthquake (MCE) Ground Motion Maps in the IBC are in terms of … S s = "short-period" (0.2-second) spectral acceleration S 1 = 1.0-second spectral acceleration Ground motions for other periods, and hence other buildings, are derived from these two spectral accelerations (as explained later)

MCER spectral response acceleration at 1-second period, S1, as determined in accordance with UFC 3-301-01, are less than or equal to 0.25 and 0.10 ...

2012年1月1日 · Updated editions of the IBC are published every 3 years. The latest edition (2012) contains new "risk-targeted maximum considered earthquake" (MCER) ground motion maps, which are enabling engineers to incorporate a more consistent and better defined level of seismic safety into their building designs.

Engineers should typically use the tools below for seismic design; the parameter values they provide are not typically identical to those from hazard tools available elsewhere on the USGS website.

2019年10月26日 · ICC 于 1997 年发布了新版规范的草案，经讨论修订，最终于 2000 年正式发布“国际建筑规范”（International Building Code，简称 IBC 规范），与此同时， UBC 、NBC 、SBC 规范分别在 1997、1999、1999 年推出最终版后不再继续更新，IBC 规范 实现了对 3 个模式规范 …

2025年2月21日 · Structural design guidelines, informed by MCE and MCER calculations, prioritize the integration of site-specific seismic data, enhanced ductility requirements, and advanced analytical methods to ensure resilient and sustainable infrastructure.

2023年7月13日 · 用于计算和确定SLE和MCER水准下的地震加速度反应谱。根据场地和结构动力特性，根据现场特定地震危险性概率分析(probabilistic seismic hazard analysis，简称PSHA)得出的MCER纵坐标不得低于ASCE 7-16第11章规定的纵坐标的20%以上。

The IBC SEAOC Structural/Seismic Design Manual, throughout its many editions, has served the purpose of illustrating good seismic design and the correct application of building-code provisions. The Manual has bridged the gap between the discursive treatment of topics in the SEAOC Blue Book (Recommended
