Coastal cities face imminent challenges of land scarcity due to over-population and rising sea levels. Floating structures offer a solution to both of these challenges by creating new living space that adapts to water level variations. While small-scale floating urban developments have been prevalent in sheltered areas, large-scale implementations in challenging sea conditions hold the key to addressing coastal city issues effectively. The design of such structures faces technical challenges related to internal loads and human comfort. Typically, large structures are subjected to high internal loads, while small structures are exposed to larger motions, resulting in a lower level of comfort. The application of compliant mechanical connectors between modules of large floating structures is an alternative for attaining an adequate balance between internal loads and comfort level. This study addresses the analysis of a multi-platform floating structure for urban applications subject to wave action. In particular, it focusses on how the platform comfort level is influenced by the connection bending stiffness. The interaction between waves and floating structures is computed using a radiation-diffraction boundary-element method. Each platform is represented as a six degree-of-freedom rigid body, which incorporates two buildings. The connectors are modelled as generic six degree-of-freedom springs located between neighboring platforms. Results demonstrate the dependency of comfort levels and bending moments on the connector bending stiffness and incident wave conditions. For an adequate combination of wave period and bending stiffness, the compliant connector provides a good balance between comfort and loads, when compared with flexible and rigid connectors.
