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

An experimental study of precast concrete moment frames under a column removal scenario

September 1, 2017
Author(s)
Hai S. Lew, Joseph A. Main, Yihai Bao, Fahim Sadek, Vincent P. Chiarito, Stephen D. Robert, Jorge Torres
This paper presents a full-scale experimental study of two precast concrete moment-frame assemblies, each comprising three columns and two beams. The assemblies represented portions of seismically designed perimeter moment frames from two 10-story

Performance of Composite Beams in Fire: Pre-test Analysis of Full-scale Experiments

July 23, 2017
Author(s)
Joseph Main, Fahim H. Sadek, Jonathan Weigand, Jian Jiang, Lisa Choe, Selvarajah Ramesh, Matthew Hoehler, John L. Gross
This paper presents results from pre-test analysis of a full-scale 42 ft (12.8 m) span composite beam with bolted angle connections, under uniform gravity loading simulated using six equally spaced concentrated loads, and subjected to a 4000 kW compartment

Enhanced connections for improved robustness of steel gravity frames

October 12, 2016
Author(s)
Jonathan Weigand, Joseph Main
Potential vulnerabilities to collapse have been identified for steel gravity framing systems with conventional gravity connections subjected to column loss. To address these potential vulnerabilities, a high-fidelity finite element modeling approach is

Numerical modeling of heat transfer in steel-concrete composite slabs

June 10, 2016
Author(s)
Jian Jiang, Joseph A. Main, Jonathan M. Weigand, Fahim Sadek
This paper presents detailed and reduced-order numerical modeling of heat transfer in composite floor slabs with profiled steel decking. The detailed modeling approach represents the concrete slab with solid elements and the steel decking with shell

A SIMPLE METHOD OF ENHANCING THE ROBUSTNESS OF R/C FRAME STRUCTURES

June 1, 2016
Author(s)
Yihai Bao, Hai S. Lew, Fahim Sadek, Joseph A. Main
A simple debonding technique is proposed to reduce or eliminate strain localization in reinforcing bars in the region of wide flexural cracks in RC beams to enhance the resistance of RC buildings to disproportionate collapse (also referred to as

Temperature-Dependent Material Modeling for Structural Steels: Formulation and Application

April 15, 2016
Author(s)
Mina S. Seif, William E. Luecke, Lisa Y. Choe, Joseph A. Main, Joseph D. McColskey, Chao Zhang, Jonathan M. Weigand, John L. Gross, Fahim Sadek
This report presents the formulation and application of a newly developed temperature-dependent material model for structural steels. First it presents a model for computing the stress-strain behavior of structural steel for conditions appropriate to fire
