The adequate seismic behavior of slender reinforced concrete (RC) structural walls relies heavily on the effectiveness of the boundary element (BE) in providing stable resistance against combined axial and flexural-shear compression demands resulting from

Although ductility is a foundational attribute of seismic design, it is not sufficient to provide seismic stability. Instead, persistent positive stiffness that obviates the destabilizing effects of gravity is the essential attribute that prevents

This NIST Technical Note presents the User's Manual for the DAD_PBD version 2.0 software, a user-friendly tool for the advanced structural design of dynamically sensitive steel and reinforced concrete buildings. The software utilizes the Database-Assisted

Significant tornado events have prompted a push for the development of design standards that consider tornado loading for conventional buildings and structures. One important loading parameter in the design standards is the variation in the horizontal wind

The Structural Engineering Institute (SEI) has a long history of working with NIST and other federal partners to improve ASCE/SEI 7 Minimum Design Loads and Associated Criterial for Buildings and Other Structures, the national loading standard. Following
Designing buildings for improved functional recovery represents a major shift in the current design paradigm. Given the novelty of the functional recovery building performance objective, current design provisions may be ineffective at controlling the
As part of the ACI 374A Subcommittee on Design of Reinforced Concrete Structure for Functional Recovery, the authors held six expert panel discussions with experts in various aspects of building design and construction. The goal of the discussions was to
Computational fluid dynamics (CFD) simulation has become increasingly popular for evaluating the topographic effects on wind fields due to its relative advantage over experimental techniques in accurately generating approach flows and capturing complex

In recent years, wind design, particularly for high-rise buildings, has seen a paradigm shift from a code-based descriptive method to a more specific performance-objective-based design. This new approach, known as the Performance-Based Wind Design (PBWD)

This NIST Technical Note presents a User's Manual of the DAD_PBD software for mid- and high-rise steel structures. A Database-Assisted Design (DAD) method for the design of tall buildings that utilizes time-varying aerodynamic pressure data from wind
As building codes in the United States move toward the development of functional recovery provisions aimed at reducing recovery times following earthquakes, it is critical to benchmark how buildings designed following life-safety provisions perform in
In the field of structural engineering, functional recovery is a new, but non-standardized building design objective intended to improve a building's capacity to maintain or rapidly restore basic intended functions after a hazard event, such as an
Buildings repetitively framed with cold-formed steel (CFS) members often possess significant lateral overstrength due to contributions from components beyond the designated sheathed or strap-braced shear walls, including from the gravity framing, non
Buildings in seismic regions are designed to sustain significant damage during major earthquakes with collapse. Traditional linear design procedures use a force-based approach to size the building structural members. Alternatively, performance-based
In a building, seismic stability is provided when the internal restoring forces resist the effective earthquake forces plus the destabilizing effects of gravity that arise when the building displaces laterally. Although this concept can be succinctly

Earthquake reconnaissance trips have become the norm following major seismic events. Traditional approaches to data collection involve gathering photographs, structural measurements, and notes on qualitative damage. While these traditional activities

A survey was conducted across 10 cities in Southeast Türkiye to classify damage in 242 reinforced concrete (RC) buildings constructed in the last 15 years, ranging from 2 to 16 stories. The 'robustness' of these buildings was quantified using ratios of

This paper reviews the state of the art in using benefit–cost analysis (BCA) to inform earthquake risk reduction decisions by building owners and policymakers. The goal is to provide a roadmap for the application and future development of BCA methods and
Computational fluid dynamics (CFD) simulations for structural wind engineering applications require a fully developed boundary layer approach flow with horizontal homogeneity and zero pressure gradient for accurate characterization of wind loading on a
