Preloaded foundation capacity has recently been a topic of major interest in offshore foundation engineering. The increase in undrained shear strength due to preloading and consolidation enables the foundation to resist a larger environmental load, thereby reducing the size of the footprint. This paper investigates the shape and size of the VHM (i.e., vertical, horizontal, and moment) capacity surface of a skirted circular foundation by comparing both the no-preload and the post-preload responses using coupled small strain finite-element analyses. The influence of the distribution of in situ undrained shear strength, the magnitude of vertical preload, and the duration of consolidation on the..View full abstract
