Curtis Wood, E.L. Robinson Engineering senior structural engineer, recently published a research paper in the AISC Steel Construction Journal. This journal article is part of Curtis Wood’s Doctor of Philosophy research on progressive collapse.
This paper presents experimental and numerical investigation of progressive collapse vulnerability of an existing steel building, Haskett Hall, on the Ohio State University (OSU) campus. The building was tested by removing one of the first-story columns to observe its collapse resistance and to evaluate the effectiveness of current modeling and analysis guidelines. Progressive collapse is a relatively large partial or complete collapse of a structure due to the loss of a vertical load carrying element; a column in this case. Few researchers have been able to conduct full-scale experiments to understand the progressive collapse mechanism. In this research, deflections and deformations of steel structural components were measured during the field experiment. Computational models and simulations were examined and compared with the experimental data from the field tests. The contribution and effects of infill walls to progressive collapse resistance of frame structures were investigated. The test data collected in this research can be used to help develop recommendations for improved procedures for progressive collapse analysis of frame buildings.
