Jul 01, 2020  1. Introduction. Reinforced hollow concrete columns (HCCs) constitute a structurally efficient construction system for offshore and marine structures, including piles and bridge piers due to their high strength-to-mass ratio compared to solid columns with the same concrete area [1,2].HCC structural behavior is controlled by a number of critical design parameters, including inner-to-outer ...
