Guidelines For Nonlinear Structural Analysis And Design Of Buildings Part Iia

Guidelines for Nonlinear Structural Analysis and Design of Buildings, Part IIa

In 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 develop guidance for nonlinear dynamic analysis (ATC-114 Project). The need for such guidance is identified as high-priority research and development topic (Proposed Research Initiative 6) in NIST GCR 14-917-27 report, Nonlinear Analysis Research and Development Program for Performance-Based Seismic Engineering (NIST, 2013), 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. In addition, the NIST GCR 09-917-2 report, Research Required to Support Full Implementation of Performance-Based Seismic Design (NIST, 2009), also identified the need to improve analytical models for buildings and their components in near-collapse seismic loading. To help fill this gap, the ATC-114 Project developed a series of reports that provide general nonlinear modeling and nonlinear analysis guidance, as well as guidance specific to the following two structural systems: structural steel moment frames and reinforced concrete moment frames. This Part IIa report, referred to as Guidelines herein, provide practical guidance for nonlinear modeling and analysis specific to steel moment-resisting frames and their components. It is a companion to Part I Guidelines (NIST, 2017) that provides general guidance on nonlinear analysis. Other Part II companion reports provide further details for selected system types.

Proceedings of the 11th International Conference on Behaviour of Steel Structures in Seismic Areas

This volume highlights the latest advances, innovations, and applications in the field of seismic design and performance of steel structures, as presented by leading international researchers and engineers at the 11th International Conference on the Behaviour of Steel Structures in Seismic Areas (STESSA), held in Salerno, Italy, on July 8-10, 2024. It covers a diverse range of topics such as behaviour of structural members and connections, performance of structural systems, mixed and composite structures, energy dissipation systems, self-centring and low-damage systems, assessment and retrofitting, codes and standards, light-gauge systems. The contributions, which were selected by means of a rigorous international peer-review process, present a wealth of exciting ideas that will open novel research directions and foster multidisciplinary collaboration among different specialists.
