This paper highlights the importance of accounting for three dimensional effects when
modeling progressive collapse behavior. Two types of nonlinear, inelastic models are first …

Assumptions must necessarily be made when the collapse response of structures is
investigated using simulation models. The type and extent of modeling assumptions depend …

Progressive collapse denotes a failure of a major portion of a structure that has been
initiated by failure in a relatively small portion of the structure. One approach to evaluate …

Progressive collapse is a complex process in which failure of a single component leads to
collapse of a disproportionately large part of the structural system. Recent building and …

A clear comprehension of the nonlinear behavior of reinforced concrete (RC) structural
components and systems undergoing large displacements is essential to assess the safety …

The main goal of this research is to better understand progressive collapse mechanisms of
buildings, and to evaluate the current modeling and analysis techniques and design …

When designing for the limit state of collapse prevention, engineers must be able to compute
the ways in which structural components fail and how the failure of one or several members …

The potential for progressive collapse of a typical reinforced concrete (RC) moment frame
structure initiated through the loss of one or more first-story columns is numerically simulated …

Although many of the key physical phenomena associated with progressive collapse can be
adequately modeled by high fidelity finite element analysis, such models are prohibitively …

A field experiment and numerical simulations were performed to investigate the progressive
collapse potential of an existing steel frame building. Four first-story columns were physically …
