“…If the model is created per the recommendations in this document, the same component model should respond correctly when monotonically pushed and also respond correctly when cyclically loaded with any type of cyclic loading protocol. To illustrate this, test data are presented for a series of identical full-scale reinforced concrete columns recently tested under various loading protocols (data and figures are after Nojavan et al, 2014Nojavan et al, , 2016.…”

PrefaceIn September 2014, the Applied Technology Council (ATC) commenced a task order project under National Institute of Standards and Technology (NIST) Contract SB1341-13-CQ-0009 to conduct comprehensive review of the generalized component models published in the current ASCE/SEI standard and relevant research, and develop recommendations for improvement . The need for defining parameters for nonlinear force-deformation models for components, elements, or assemblies is identified as a high-priority research and development topic in NIST GCR 14-917-27 report, Nonlinear Analysis Study and Development Program for Performance-Based Seismic Engineering, (NIST, 2013b) which outlines a research and development program for addressing the gap between state-of-the-art academic research and state-of-practice engineering applications for nonlinear structural analysis, analytical structural modeling, and computer simulation in support of performance-based seismic engineering. Buildings (ASCE, 2014), is widely used by designers for evaluating and upgrading existing buildings. The component models in the current standard were developed for use in existing building analysis, but they have also become widely employed in new building analysis. The purpose of this report is to recommend broad improvements to seismic nonlinear modeling and acceptance criteria requirements for different structural systems.

The primary intended audience for this report are committee members engaged in the development of building code requirements for the use of nonlinear analysis in design, though individual engineers engaged in performance-based engineering projects may find the information presented herein useful.Nonlinear static and dynamic analysis are commonly used by engineers to assess the probable performance of existing buildings and to design major new buildings. The most comprehensive guidelines presently available for performing nonlinear seismic analysis are contained in ASCE/SEI 41-13, Seismic Evaluation and Retrofit of Existing Buildings (ASCE, 2014). This guidance includes recommended backbone shapes and control points that describe the envelope of hysteretic response of various structural elements when subjected to ramped, fully-reversed, cyclic loading protocols. Most of these backbone recommendations are based on data available in the mid-1990s. Substantial additional research has been conducted since that time, enabling the development of updated backbones and control points for steel braced frame and moment frame, reinforced concrete shear wall and moment frame, and masonry and wood shear wall structur...

Development of collapse‐consistent loading protocols for experimental testing of steel columns

In order to effectively utilize results from quasi-static cyclic testing on structural components for the earthquakeinduced collapse risk quantification of structures, the need exists to establish collapse-consistent loading protocols representing the asymmetric lateral drift demands of structures under low-probability of occurrence earthquakes. This paper summarizes the development of such protocols for experimental testing of steel columns prone to inelastic local buckling-induced softening. The protocols are fully defined with a deformation-and a force-controlled parameter. They are generally applicable to quantify the capacity and demands of steel columns experiencing constant and variable axial load coupled with lateral drift demands. Through rigorous nonlinear earthquake collapse simulations, it is found that the building height, the column's local slenderness ratio and ground motion type have the largest influence on the dual-parameter loading protocol indexes. Comprehensive comparisons with measured data from fullscale shake table collapse tests suggest that, unlike routinely used symmetric cyclic loading histories, the proposed loading protocol provides sufficient information for modeling strength and stiffness deterioration in steel columns at large inelastic deformations.
