Description
The purpose of this paper is to research and analyze the effects of seismic forces on bridge substructure support caps with steel pipe piles using the finite element method. Trestle bents, or pile supports, act as an intermediary between the girder loads and the piles that carry those loads. These piles do not experience bending moments from the superstructure like a frame bent would, but they can experience potential moments due to seismic forces. A single support is modeled in finite element software with response spectrum values input into the software to run an analysis. Using the AASHTO Guide Specification for LRFD Seismic Bridge Design as a guide will determine the overall resistance of the structure when subjected to seismic forces. The analysis will hope to demonstrate the stresses and displacements the pile experiences as well as its effects on the superstructure it is supporting. Displacement demands and capacities serves as the seismic design basis for the structure. If the demand becomes greater than the capacity, then the structure fails.
