N2 - Inspired by architect-engineer Félix Candela, we present an innovative structural system consisting of four-sided hyperbolic paraboloid (hypar) umbrellas as hard countermeasures against nearshore hazards. The umbrellas line the coast and remain upright during normal operation, providing shade and shelter along the waterfront while not limiting visibility and access to the shore. A hinge at the hypar-column interface enables tilting such that the panels can transition into a physical barrier against surge induced coastal inundation during imminent hazard scenarios. A decoupled numerical scheme constituting smoothed particle hydrodynamics (SPH) and the finite element method (FEM) was implemented to simulate hydrostatic inundation on the frontal surface of a tilted umbrella as a proof-of-concept. In assuming concrete construction, the study successfully illustrated the applicability of deployable hypar shells as coastal armor from a structural engineering perspective. This work ultimately demonstrates the feasibility of decoupled SPH-FEM methods in modeling fluid-structure interaction involving hypar forms, while establishing a foundation for their analysis and design for coastal hazard adaptation.
