轻量化的海上建设概念有可能节省成本，因为作为主要成本要素之一的物流费用被降至最低。为了用混凝土建造轻质结构，必须开发新的建筑概念来取代传统的重型建筑技术。这些建筑理念不仅带来了形式上的优化，而且在材料选择上也产生了新的组合，即“材料追随力”。除了有利的生产条件外，这两个原则的结合形成了UHPC-钢混杂管材概念的核心理念。本文研究的重点是超高强度钢混杂钢管结构的受力机理。特别是，会议将讨论偏心加载的混合管组件的承载行为，作为海上夹套式支撑结构组件的特征载荷情况之一。
Lightweight offshore construction concepts have the potential to save costs, as expenses for logistics as one of the main cost element are minimized. In order to build lightweight structures with concrete, novel construction concepts have to be developed to substitute traditional heavy building techniques. These construction concepts not only lead to form-optimized constructions, but also to new combinations in the material choice in the sense of "material follows force". In addition to favorable production conditions, uniting both of these principles forms the core idea of the UHPC-steel hybrid tube concept. The focus of this proceeding lies in load bearing mechanisms of UHPCsteel hybrid tube structures. In particular, the proceeding will address the bearing behavior of eccentrically loaded hybrid tube components as one of the characteristic load situation for components of offshore jackettype support structures.
