摘　　要：大力发展和推广应用高强混凝土材料满足我国可持续发展战略需求,促进建筑领域"双碳目标"的实现,已成为我国高层建筑领域的主要发展方向之一。基于应用高强材料的过程中经常面临的材料强度与延性难以统一协调的问题,阐述了高强混凝土在装配式高层建筑中的应用思路,结合装配式建筑的特点,提出了一种新型的高强混凝土装配式高层框架结构体系,该结构体系采用具有大变形能力的装配式节点和消能减震技术,并对该结构体系进行了抗震性能试验。结果表明:该结构体系具有良好的抗震性能,耗能系统工作良好,实现了整体结构预设的破坏模式,且能充分利用高强混凝土材料、消能减震技术的优势,形成具有高抗震安全性、高耐久性、施工便利的装配式高层建筑结构。Vigorously developing and popularizing high strength concrete materials meet the needs of China sustainable development strategy and also contribute to the realization of the "dual carbon goals", which has become one of the main development directions in the field of high-rise buildings in China. Based on the problem that the strength and ductility of high strength materials are difficult to be harmonized in the process of applying high strength materials, the application ideas of high strength concrete in assembled high-rise building structures were expounded. According to the characteristics of assembled buildings, a new type of assembled high-rise frame structure system with high strength concrete adopting assembly joints with large deformation capacity and energy dissipation technologies was proposed, and the seismic performance test of the structural system was carried out. The results show that the structural system has good seismic performance, the energy dissipation system works well, and the predetermined failure mode of the whole structure is implemented. The structural system can also make full use of the advantages of high-strength concrete materials and energy dissipation technology to form a assembled high-rise building structure with high seismic safety, high durability and convenient construction.
