RISSize Effect on Strength Statistics of Prenotched Quasibrittle Structures
Publisher: ASCE
Abstract: This paper presents a stochastic analysis of the size effect on the nominal strength of quasibrittle structures with a large preexisting notch. This type of scaling behavior has been extensively studied within a deterministic ...
Stochastic Computational Model for Progressive Collapse of Reinforced Concrete Buildings
Publisher: American Society of Civil Engineers
Abstract: A two-scale numerical model is developed to investigate the probabilistic collapse behavior of reinforced concrete (RC) buildings subjected to local structural damage. In this model, a set of coarse-scale cohesive elements ...
Stochastic Computational Model for Progressive Collapse of Reinforced Concrete Buildings

Abstract: A two-scale numerical model is developed to investigate the probabilistic collapse behavior of reinforced concrete (RC) buildings subjected to local structural damage. In this model, a set of coarse-scale cohesive elements ...
Scaling of Static Fracture of Quasi-Brittle Structures: Strength, Lifetime, and Fracture Kinetics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper reviews a recently developed finite chain model for the weakest-link statistics of strength, lifetime, and size effect of quasi-brittle structures, which are the structures in which ...

Failure Probability of Concrete Specimens of Uncertain Mean Strength in Large Database
Publisher: ASCE
Abstract: A general framework for analyzing the failure probability of concrete specimens with the mean strength sampled from a large database is presented. The framework explicitly takes into account the level of uncertainty of the ...
Closure to “What Did and Did Not Cause Collapse of World Trade Center Twin Towers in New York?” by Zdeněk P. Bažant, Jia-Liang Le, Frank R. Greening, and David B. Benson
Publisher: American Society of Civil Engineers
Why the Observed Motion History of World Trade Center Towers Is Smooth
Publisher: American Society of Civil Engineers
Abstract: The collapse of the World Trade Center towers was initiated by the impact of the upper falling part onto the underlying intact story. At the moment of impact, the velocity of the upper part must have decreased. The fact ...
Numerical Modeling of Delayed Progressive Collapse of Reinforced Concrete Structures
Publisher: ASCE
Abstract: There has been ever-increasing interest over the past decade in improving understanding of the mechanisms responsible for the progressive collapse of structures. Existing design recommendations and analyses are largely ...
Spontaneous Collapse Mechanism of World Trade Center Twin Towers and Progressive Collapse in General
Publisher: ASCE
Abstract: The collapse of the World Trade Center (WTC) Towers during the terrorist attacks on September 11, 2001, remains one of the most tragic catastrophes in the field of structural engineering. This paper first reviews a ...
