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

Integrity of Bolted Angle Connections Subjected to Simulated Column Removal

December 8, 2015
Author(s)
Jonathan M. Weigand, Jeffrey W. Berman
Large-scale tests of steel gravity framing systems (SGFSs), one of the most commonly used structural systems in the United States, have shown that enhancements may be required to achieve the desired levels of integrity to collapse when a column suffers

Analysis of a Half-Scale Composite Floor System Test under Column Loss Scenarios

April 23, 2015
Author(s)
Joseph A. Main, Jonathan M. Weigand, Eric S. Johnson, Tim Francicso, Judy Liu, Jeffrey W. Berman, Larry A. Fahnestock
This paper describes modeling and analysis of a half-scale steel gravity frame system with composite concrete slab on steel deck that was constructed and tested at the University of Illinois under corner, edge, and interior column removal scenarios. For

New Steel Gravity Connection Details for Enhanced Integrity

April 23, 2015
Author(s)
Jonathan M. Weigand, Jeffrey W. Berman
Recent large-scale tests have found that Steel Gravity Framing Systems (SGFSs) with conventional connections were inadequate to support the integrity gravity load combinations under column removal scenarios. To address this issue, detailed connection

EXPERIMENTAL STUDY OF RC ASSEMBLIES UNDER A COLUMN REMOVAL SCENARIO

July 1, 2014
Author(s)
Hai S. Lew, Yihai Bao, Santiago Pujol, Mete Sozen
This paper presents an experimental study of two full-scale reinforced concrete (R/C) beam-column assemblies under a column removal scenario. The assemblies represent portions of the exterior moment-resisting frames of two ten-story R/C frame buildings

Robustness Assessment of RC Frame Buildings under Column Loss Scenarios

April 3, 2014
Author(s)
Yihai Bao, Joseph A. Main, Hai S. Lew, Fahim Sadek
A computational assessment of the robustness of reinforced concrete (RC) building structures under column loss scenarios is presented. A reduced-order modeling approach is presented for three-dimensional RC framing systems, including the floor slab, and

Robustness of Precast Concrete Frames: Experimental and Computational Studies

April 3, 2014
Author(s)
Joseph A. Main, Yihai Bao, Hai S. Lew, Fahim Sadek
This paper describes both full-scale testing and detailed finite-element modeling of a precast concrete moment-frame assembly extracted from the perimeter moment frame of a 10-story prototype building. The assembly comprises two beam spans and three

A Simple Means for Reducing the Risk of Progressive Collapse

December 1, 2013
Author(s)
Yihai Bao, Hai S. Lew, Fahim H. Sadek, Joseph 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, and as a result enhance the resistance of RC buildings to disproportionate collapse. In this study
