Reliable analytical and empirical models of the force-deformation parameters used to characterize the nonlinear behavior of masonry infill panels are essential to simulating the seismic response of the masonry-infilled reinforced concrete and steel frame
A 160-foot tall 12-story reinforced concrete special moment frame building is designed following ASCE 7-10 and ACI 318-14, and assessed using three Performance-Based Seismic Engineering (PBSE) standards and guidelines including ASCE/SEI 41, the Tall

This paper presents a methodology for estimating seismic retrofit costs from historical data. In particular, historical retrofit cost data from FEMA 156 is used to build a predictive model to estimate retrofit costs as a function of building

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
Various sources of uncertainties including material, modeling, and loading uncertainties can have a significant influence on prediction of earthquake-induced damage and estimates of the collapse risk of a building obtained through the performance-based
Can small-displacement-based structural analysis software packages possibly be used to simulate large displacement responses and structural collapse due to earthquake excitations? This question has been raised by both researchers and practitioners over and

In NIST TN 1973 [1], we develop a methodology for estimating seismic retrofit costs. The general approach is to build a predictive model of seismic retrofit costs that (1) captures the essential factors that drive costs, such as building construction type
This paper presents the results of a seismic performance assessment using ASCE 41-06 for six buckling-restrained braced frames (BRBFs) designed in accordance with the 2012 International Building Code. The correlation between ASCE 7-10 and ASCE 41-06 is
