Time-Dependent Response of Reinforced Concrete Buildings near Collapse
Summary: The goal of this research is to understand the impact of sustained gravity loads on the evolution of large-scale collapse in reinforced concrete (RC) buildings. The goal will be accomplished by integrating experimental testing, computational modeling, and probabilistic collapse assessment.

Evaluation of Finger Plate and Flat Plate Connection Design
Summary: This project investigates the cause(s) of premature deterioration of MoDOT finger plate and flat plate expansion devices under high traffic volumes and then uses that information to design new Load and Resistance Factor Design (LRFD) finger plate and flat plate designs that are intended to last 40 years or more with minimal maintenance.

Integrated Experimental and Analytical Evaluation of Dynamic Progressive Collapse in Flat-plate Buildings
Summary: The overall goal of this project is to evaluate the potential of dynamic progressive collapse in older reinforced concrete flat-plate buildings subjected to the sudden loss of an interior or exterior supporting column.
