    摘要:

    首次提出组合混凝土结构的基本概念,其基本思想是在不同的层次上(材料、构件、结构)组合不同种类的混凝土,对混凝土材料以及结构进行优化设计,从而使其性能提升,更好满足安全性、适用性和耐久性,实现可持续性。围绕这一创新思路,针对组合混凝土梁、柱、板以及框架结构等,对组合混凝土结构的设计与施工原理进行了阐述。最后对组合混凝土结构存在的科学问题及其发展趋势,包括界面设计、3D打印施工与可持续性评价进行了分析与展望。

    Abstract:

    The present paper firstly introduces a fundamental concept for a novel structure, i.e., the composite concrete structure. Taking the mechanical properties of various types of concretes into consideration, concrete in structures could be combined in different levels (material, component and structure) according to this new concept. Through optimization design, the safety, serviceability and durability of concrete structures could be significantly improved, and the sustainability of concrete structures could be achieved consequently. Based on the proposed new concept, case studies were carried out, including composite concrete beams, columns, slabs and frame structures. Finally, the scientific problems and future development of composite concrete structures, including interface design method, 3D-printing construction technique and the sustainability evaluation, are suggested and analyzed. Recommendations for future investigations are also put forward.
