Use straight-line interpolation for intermediate values of mapped spectral response acceleration at 1-second period, S1. Values shall be determined in accordance with Section 11.4.8 of ASCE 7. See requirements for site -specific ground motions in Section 11.4.8 of ASCE 7. Explore a searchable database of US construction and building code.

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.

For designing buildings and other structures to safely resist earthquakes, the 2009 NEHRP Recommended Seismic Provisions and the 2010 ASCE/SEI 7 Standard contain maps of Risk-Targeted Maximum Considered Earthquake (MCER) spectral response accelerations and maps of Maximum Considered Earthquake Geometric Mean (MCEG) peak ground accelerations.

The design of this building used performance-based engineering with performance objectives and ground motions defined by ASCE1; Maximum Considered Earthquake (MCER) ground motions are the lesser of the 2,500-year average return period probabilistic ground motions and the deterministic (median + σ) ground motions.

2019年10月26日 · 为此，提出 以 MCER 取代 MCE 作为建筑抗震设计最大考虑地震作用。 MCER 是满足 50 年倒塌概率 1%风险目标的最大考虑地震，它的确定综合了概率地震危险性曲线与地震作用下结构倒 塌率的不确定性分布（Luco 等，2007 ）。

According to ASCE 7-16, the design response spectrum is determined by multiplying the risk-targeted maximum considered earthquake (MCER) response spectrum by (2/3).

2022年7月19日 · Table 1 shows an example of spectral acceleration MCE G calculation at point P. Table 2 shows an example of MCE R -S S calculation at point Q. The difference of the MCE G or MCE R -S S results calculated using WS and SAS can also be seen in Tables 1 and 2.
