The result of that humongous effort is the soon-to-be released ASCE 41-13: Seismic Evaluation and Retrofit of Existing Buildings. 2% probability of exceedance in 50 yearsīSE–2E: BSE-2 for use with Basic Performance Objective for Existing Building, taken as a seismichazard with a 5% probability of exceedance in 50 years, but not greater than BSE-2N, at a site.īSE–1N: BSE -1 for use with Basic Performance Objective Equivalent to New Building Standardstaken as two-thirds of BSE-2N, at a site. For the past 3 years the ASCE/SEI Standards Committee on Seismic Rehabilitation has been working to combine ASCE 31-03 into ASCE 41-06 while also updating both standards.

ASCE 41-13 has two sets of explicitly that approximates the performance objectives within ASCE defined performance objectives, the Basic Performance 31-03 which accepted a higher level of risk.
