Internal stress during concrete curing. Numerical analysis supports
concrete expansion and contraction, heat release due to hydration
surrounding environment, material property changes due to hydration,
crack propagation, compression and tension stress, effects of rebar
and access tubes, debonding, soil contraction, etc.

Internal stress during shaft loading
Internal cracking during curing phase. Shaft debonds from surrounding
rock, weakening side friction support. Crack propagation shows access
tube debonding, rebar debonding, internal cracking, and external
exposure to potential contamination and corrosion.
