Paper Published in Engineering Structures
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…

Thermal Response For Steel I-Girder Bridges: Data Measurements On-Going at UTRGV
Two beams are positioned outside the Department of Civil Engineering Department at the University of Texas Rio Grande Valley as part of a research project to evaluate thermal response for steel I-girder bridges. This experimental effort aims to measure vertical thermal gradient on exterior (exposed) girders due to uneven heating from solar radiation, which can…
