Integral Abutment Bridge Design – LA 160 Bridges Project

• A primary component of integral bridge design is the design of the H-piles supporting the abutment • For longer bridges, the abutments can be subjected to relatively large thermal displacements, which in turn induces large stresses in the H-piles • The PennDOT design procedure employs two primary checks to ensure integrity of the piles:

Expansion joint - Wikipedia

An expansion joint or movement joint is an assembly designed to safely absorb the temperature-induced expansion and contraction of construction materials, to absorb vibration, to hold parts together, or to allow movement due to ground settlement or earthquakes. They are commonly found between sections of buildings, bridges, sidewalks, railway tracks, piping systems, ships, and other structures.
