000018204 520__ $$2eng$$aThe American Concrete Institute’s Committee 369 is working on a new national standard that will be the source document for the concrete provisions of the ASCE/SEI 41 standard on “Evaluation and Retrofit of Existing Building”. The first edition of the standard is expected to be published in 2017. As part of that effort, the nonlinear modeling parameters in ASCE/SEI 41-13 defining the lateral-load versus lateral-strength response of concrete columns were updated. The proposed new modeling parameters target median response values as opposed to the current conservative estimates, so as not to skew analytical responses. In this new approach, conservatism is introduced in the acceptance criteria associated with the modeling parameters. Independent parameters were produced for spirally reinforced circular columns, which exhibited deformation capacities roughly 30% larger than those of comparable rectangular columns. A new methodology for assessing splice deficiencies in concrete columns was introduced. The methodology accounts for loss of bond strength in regions of inelastic hinging and damage. Modeling parameters for column with splice deficiencies were modified based on the new methodology from those currently in the ASCE/SEI 41-13 standard.
