The American Society of Civil Engineers (ASCE) performance-based seismic design standard, ASCE 41, contains methodologies used by practicing engineers to assess existing buildings and to design new buildings. In 2015, the National Institute of Standards

This study quantifies the impact of two common ground motion (GM) selection methods, included in U.S. standards, on the seismic performance evaluation of steel special moment frames. The methods investigated are a "traditional" approach, herein referred to

An accurate yet simple estimate of the retrofit cost plays an important role in the decision-making process of retrofitting existing buildings. Fung et al. (2018a) develop a predictive model to estimate seismic retrofit costs as a function of building
The seismic behavior of a building component (e.g., shear wall) is a fundamental attribute engineers need to assess the earthquake performance of a building. It is no surprise that component behavior is often dependent on the loading history. Repeatedly

The intent of current building codes for typical commercial and residential buildings is to safeguard against loss of life to building occupants by minimizing the probability of structural collapse during natural hazard events. However, current codes do

For typical residential and commercial buildings, the intent of buildings codes is to protect building occupants against life-threatening actions while providing some degree of property protection during natural hazard events. As a result, new and existing

The performance of buildings in our communities depends on multiple factors including the availability of supporting infrastructure, the original design, the current condition and capacity to resist hazard impacts, and the ability to recover functionality
This paper presents the results of a study investigating the correlation between the seismic performance of an ASCE 7 code-compliant steel building with special moment frames and its associated seismic performance as quantified using ASCE 41 analysis

Presidential Executive Order 13717, Establishing a Federal Earthquake Risk Management Standard, encourages federal agencies to enhance resilience [to] future earthquakes by evaluating and retrofitting existing federal buildings based on current existing
ASCE 41 component backbone curves are typically based on envelopes of data from lab tests of specimens subjected to simulated seismic demands. Prior editions of ASCE 41 required loading protocols having fully-reversed cyclic loading at increasing
