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

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

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

A Simple Means for Reducing the Risk of Progressive Collapse

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

Modeling of Reinforced Concrete Assemblies under a Column Removal Scenario

November 8, 2012
Author(s)
Yihai Bao, Hai S. Lew, Sashi K. Kunnath
This paper presents a computational investigation of two reinforced concrete beam-column assemblies, each comprising three columns and two beams, subjected to monotonically increasing vertical displacement of the unsupported center column simulating a
