We examine several analytical approaches to estimate the minimum safe distance conditioned on the occurrence of risk-targeted maximum considered earthquake (MCE R ) shaking: 1) elastic spectral displacement response of the adjacent buildings at the top of the shorter building, accounting for mode shape and the height difference, 2) ASCE 710’s equivalent lateral force procedure, and 3) multiple linear elastic dynamic structural analyses of the two adjacent buildings, factoring drift estimates by ASCE 7-10’s C d /R to approximate nonlinear response. We assume here that linear dynamic is the most accurate of the three and measure the safety of the others relative to it. Considering a suite of levels of MCE R shaking and combinations of building heights and structural systems, both the more-approximate approaches appear to give modestly conservative estimates of safe separation distance. The spectral-response approach would be safe with 66% probability and the equivalent lateral force approach with 90% probability, assuming that multiple linear elastic structural analyses give a fairly accurate estimate of the true distribution of building motion. In other work we examine multiple nonlinear dynamic analysis and compare the first three with the fourth.
