Paper “Gradient-based algorithmic cross-frame cross-section optimization for skewed steel I-girder integral abutment bridge deck placement response” has appeared in Engineering Structures. This paper presents a first trail to adopt gradient-based structural optimization strategies in bridge design and analysis to achieve cross-frame cross-section optimization for skewed steel I-girder bridges with integral abutments (IABs). The optimized design…

Papers “Field and Numerical Evaluations of Static and Dynamic Live Load Response in Skewed Steel I-Girder Bridges with Stub and Integral Abutments” and “Evaluating Support Representation and Modeling Strategy for Skewed Steel I-Girder Integral Abutment Bridges during Deck Placement” have appeared in the Journal of Bridge Engineering. The “Field and Numerical Evaluation” paper documents a portion…

Paper “Parametric Study of Skewed Steel I-Girder Bridge Truck Live Load Response” has appeared in the Journal of Bridge Engineering. This paper evaluates the effect of bridge geometric parameters — including skew of 0°–70°, bridge width ranging from 8 to 26 m (27-84 ft), and abutment type (stub versus integral) — on skewed steel I-girder bridge…

Paper “Long-Term Field Response of Skewed Steel I-Girder Bridge Superstructures under Thermal Variation” has appeared in the Journal of Performance of Constructed Facilities. This paper reported more than 2 years of field monitoring of two skewed two-span continuous steel I-girder bridges in Champaign, IL, one with stub abutments (and expansion joints) and the other with…

Paper “Field and Numerical Evaluation of Lateral Bending in Skewed Steel I-Girder Bridges during Deck Placement” was selected as one an ASCE Editor’s Choice Paper for the month of February, 2024. This paper studies the behavior of skewed steel I-girder bridges during deck placement, and it’s published in (ASCE) Journal of Bridge Engineering. It presents…
