Asce 7 10 free download update#
This paper discusses the most significant changes to the standard.Īt the beginning of the standard’s update cycle, the committee discussed a number of issues that could be potential updates. The update includes significant changes to the Basic Performance Objective for Existing Buildings, the linear and nonlinear analysis procedures, and the material specific provisions. An update to the ASCE 41 standard standard was just completed.
It combined the evaluation and retrofit standard, ASCE 31-03 and ASCE 41-06, in to one standard to eliminate inconsistencies between evaluation and retrofit and made significant technical changes to both standards (Pekelnicky (Pekelnicky & Poland, Poland, 2012). Introduction ASCE 41-13 was a major advancement in the practice of seismic evaluation and retrofit. This paper provides a high-level summary summary of the changes most likely to impact practice. The updates will have significant impacts on the evaluation and retrofit approach for a variety of existing buildings. Significant revisions were were included included for the standard's standard's Basic Performance Objectives, seismic hazard used in Tier 1 and Tier 2, treatment of force-controlled components, nonlinear analysis provisions, non-structural performance levels, demands on out-of-plane wall forces, modeling parameters and acceptance criteria of steel and concrete columns, and anchor testing.
This presentation provides an overview of the recent updates to the standard in the upcoming ASCE/SEI 4117.
