A Design Conflict in Section 11.8.3-item 1 of ASCE 7-10&16 (Determination of Seismic Earth Pressures on Basement and Retaining Walls)
Posted onThe maximum considered earthquake geometric mean (MCEG) peak ground acceleration (PGAM) is commonly used in the USA to perform geotechnical evaluations including liquefaction, lateral spread, and pseudo-static slope stability analyses. However, to determine seismic earth pressures on basement and retaining walls, ASCE 7-10 and 7-16 Section 11.8.3 – item 1 allows using “Design” Earthquake PGA… Read More
