Assessing Structural Performance Using Energy

June 30, 2024

Author(s)

Kevin K F Wong

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

Collapse estimates of U.S. code-compliant steel frames and implications for an ASCE 41 assessment

September 29, 2021

Author(s)

Matthew Speicher, Kevin K F Wong, Jazalyn Dukes

ASCE 41 is a standard that contains performance-based engineering procedures sometimes used to assess and retrofit existing structures. In 2015, the U.S. National Institute of Standards and Technology completed a study investigating the relationship

IDENTIFICATION OF GEOMETRIC NONLINEARITY FORMULATIONS AND THE INFLUENCES ON STRUCTURAL DYNAMIC RESPONSES

September 15, 2020

Author(s)

Kevin K. Wong

Both ASCE/SEI 7-16 and ASCE/SEI 41-17 design standards require that P-D effects be included in the nonlinear dynamic analysis procedure for designing new and existing structures. However, software packages that perform nonlinear dynamic analysis typically

QUANTIFICATION OF SEISMIC ENERGY DEMAND IN NONLINEAR STRUCTURES THROUGH ANALYTICAL DERIVATIONS

September 15, 2020

Author(s)

Kevin K. Wong, Steven L. McCabe

Collapse Risk of Steel Special Moment Frames per FEMA P695

February 5, 2020

Author(s)

Matthew S. Speicher, Jazalyn D. Dukes, Kevin K. Wong

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

Uncertainties in Seismic Collapse Analysis of Framed Structures

April 2, 2019

QUANTIFICATION OF UNCERTAINTIES IN THE RESPONSE OF BEAM-COLUMNS IN STEEL MOMENT FRAMES

June 25, 2018

Author(s)

Siamak Sattar, Jonathan M. Weigand, Kevin K. Wong

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

Uncertainties in Small-Displacement-Based Algorithms for Simulating Structural Collapse

June 25, 2018

Author(s)

Kevin K. Wong

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

Using FEMA P695 to Interpret ASCE 41 Seismic Performance of Special Moment Frames

June 25, 2018

Author(s)

Matthew S. Speicher, Jazalyn D. Dukes, Kevin K. Wong

ASCE 41 contains methodologies used by practicing engineers for the assessment of existing buildings and the design of new buildings. The National Institute of Standards and Technology recently completed a study investigating the relationship between ASCE

Epistemic Uncertainty in Solution Algorithms for Analyzing Geometric Nonlinearity of Framed Structures

April 6, 2017

Author(s)

Kevin K F Wong, Siamak Sattar, Steven McCabe

One important aspect of performance-based earthquake engineering is developing structural models that can accurately capture key characteristics of dynamic responses up to structural collapse. This in turns requires the solution algorithm be capable of

EVALUATION OF STRUCTURAL PERFORMANCE BASED ON AN ENERGY BALANCE APPROACH

January 8, 2017

Author(s)

Kevin K F Wong, Steven McCabe

An analytical method is developed to investigate the potential energy of fully nonlinear framed structures and other energy characteristics due to earthquake ground motions. Since the potential energy relates to the stiffness of the structure, it consists

RELIABILITY OF PLASTIC ROTATION CALCULATIONS FOR DAMAGE ASSESSMENT OF MOMENT-RESISTING FRAMED STRUCTURES

January 8, 2017

Author(s)

Kevin K F Wong

Performance-based standards use plastic rotation as an important measure to determine whether the response meets the acceptance criteria for moment-resisting frames. Since plastic rotation is the key parameter in performance-based seismic engineering, the

Improved Method for the Calculation of Plastic Rotation of Moment-Resisting Framed Structures for Nonlinear Static and Dynamic Analysis

December 23, 2016

Author(s)

Kevin K. Wong, Matthew S. Speicher

Nonlinear methods of seismic analysis have been gaining acceptance by practicing engineers as a useful way of assessing and improving the seismic performance of structures in which the nonlinear behavior of components of the structural model is captured in
