Abstract
Rapid development in energy consumption caused worldwide depletion of natural
sources and degradation of the environment; therefore, the use of renewable energy
such as solar and wind energy has been highly promoted. Due to intermittency issues
such as dependency on the climate and diurnal cycles, efficient ways of utilizing
renewable energy needs to be developed. One of the alternatives is deep pile
foundation with compressed air energy storage (CAES) system. Energy generated
from solar panels or wind turbines is stored as a compressed air inside the pile
foundation. Since it undergoes complex loads including structural loadings, soil
effects and pressure induced from compressed air, thorough design and analysis are
required to meet serviceability and durability performances of the system. This paper
studies various pile design alternatives and their structural responses under these
combined loadings. Extensive finite element analyses were performed to study the
application of steel-concrete composite pile foundations. Based on the results, it was
determined that the presence of steel tubes in composite pile foundation is efficient
in preventing development of large cracks and ensures comparable performance for
the dual functional system.
