Abstract
nThe load-bearing capacity of a pier is determined by the combined effects of the load from the train and
the self-weight of the girder it supports. The bending of the pier is influenced by its height, which
necessitates a careful assessment of the pier’s thickness across various girder spans and pier heights.
This evaluation ensures that the pier can withstand the imposed loads while adhering to permissible
deflection limits. By comparing the calculated pier thickness with established standards for deflection
and load-bearing capacity, engineers can determine the appropriate thickness for the pier to ensure
structural integrity and safety. Additionally, considerations such as material properties, construction
methods, and environmental factors may also influence the design and evaluation process, contributing
to the overall stability and performance of the pier structure. In addition to the load from the train and
the self-weight of the girder, other factors must be considered in the assessment of pier thickness.
Dynamic loads, such as those induced by the passage of trains or environmental conditions like wind
and seismic activity, can exert additional stresses on the pier structure. These dynamic loads may vary
based on factors such as train speed, track curvature, and the presence of nearby structures.
Furthermore, the design of the pier must account for potential changes in loading conditions over its
lifespan. Factors such as changes in train traffic volume, modifications to the girder or track system,
and future expansion or upgrade projects may influence the long-term performance and durability of
the pier. Incorporating these considerations into the design and evaluation process ensures that the
pier can effectively support the anticipated loads while maintaining structural stability and safety.
Using thorough analysis and engineering judgment, engineers can optimize the pier design to meet the
project’s requirements and ensure the longevity of the infrastructure.
