State of the Art and Research Needs in Design for Tornadoes: Structural Engineering Institute Workshop Report

September 30, 2024
Author(s)
Donald Scott, Jennifer Goupil, Shane Crawford, Alex Griffin, Cherylyn Henry, Marc Levitan, Franklin Lombardo, John van de Lindt, Peter Vickery
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

Design Guide for New Tornado Load Requirements in ASCE 7-22

January 30, 2023
Author(s)
Erik Perfetto, James Taylor, Karah Osburn, Brian O'Connor, Marc Levitan, Jennifer Mitchell
This instructional guidance is for design professionals and building officials to help them determine when a building or other structure is required to be designed to minimum tornado loads and how to calculate design tornado forces. This guide is in

Development and Analysis of a Database of Tornado Impacts on U.S. Critical Facilities

May 17, 2022
Author(s)
Nicholas de Toledo, Marc Levitan, Jamil Malik, Warren Stewart, Katherine Johnson, Patrick Crawford
Despite the significant hazard that tornadoes pose, much remains to be learned about the impacts of tornadoes on critical facilities in the United States. While a number of post-storm reports have documented the damage from individual tornadoes or tornado

Siamak Sattar, Therese P. McAllister, Katherine J. Johnson, Christopher T. Clavin, Christopher L. Segura, Steven L. McCabe, Juan F. Fung, Leslie Abrahams, Emily Sylak-Glassman , Marc L. Levitan, Kenneth W. Harrison, John L. Harris
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

Using the IES-City Framework

July 31, 2018
Author(s)
Martin J. Burns, Joe Manganelli
This paper introduces a use case for using the IES-City Framework artifacts and methodology in the acquisition of a new smart city feature. Involving city management and potential service providers, it shows how this new feature can be acquired with

Calibration of Dynamic Pressure in a Tubing System and Optimized Design of Tube Configuration: A Numerical and Experimental Study

June 12, 2018
Author(s)
Matthew Kovaerk, Luke Amatucci, Keith A. Gillis, Florian Potra, James Ratino, Marc L. Levitan, DongHun Yeo
Accurate prediction of aerodynamic pressures on a building is a key factor in the estimation of wind loads on the building. Since the analytical approach has limited capacity in providing pressure estimates, wind tunnel testing is widely used. The

Determining Mean Recurrence Intervals for Updated Wind Maps in ASCE 7-16

February 16, 2018
Author(s)
Therese P. McAllister, Naiyu Wang, Bruce Ellingwood
ASCE Standard 7 is moving toward load requirements that are consistent with reliability-based design goals characteristic of performance-based engineering (PBE). As part of this move, reliability analyses were conducted using updated wind data to determine

Analysis of Wind Pressure Data on Components and Cladding of Low-Rise Buildings

December 1, 2017
Author(s)
Dat Duthinh, Joseph A. Main, Matthew L. Gierson, Brian M. Phillips
This paper presents a methodology for analyzing wind pressure data on cladding and components of low-rise buildings. The aerodynamic force acting on a specified area is obtained by summing up pressure time series measured at that area’s pressure taps times

Estimating peaks of stationary random processes: a peaks-over-threshold approach

December 1, 2017
Author(s)
Dat Duthinh, Adam L. Pintar, Emil Simiu
Estimating properties of the distribution of the peak of a stationary process from a single finite realization is a problem that arises in a variety of science and engineering applications. Further, it is often the case that the realization is of length T

Vulnerability and Robustness of Civil Infrastructure Systems to Hurricanes

October 10, 2017
Author(s)
Shuoqi Wang, Dorothy Reed
Civil infrastructure systems play an important role in community resilience. Without proper functioning of the infrastructure, especially power delivery, society will not recover quickly from disruptive events, such as hurricanes. In this paper, the
