Extreme thermal loadings in highway bridges
WebJan 27, 2024 · This work provides a comprehensive review of previous studies concerning the static thermal behaviors of various types of bridges, including beam bridges, arch … Webthe bridge, regardless of skew, substantially reduces weak-axis bending. As a result, lighter H-pile sections and/or greater IAB lengths may be possible in skewed bridges. • The authors recommend use of compacted granular backfill behind the abutments. Except in bridges with extreme skews (beyond 45°), backfill pressures are beneficial
