型钢混凝土竖向混合结构过渡层抗震性能研究综述

Review of Studies on Seismic Design of Transition Story of Steel Reinforced Concrete(SRC) Vertical Hybrid Structures

型钢混凝土竖向混合结构是钢-混凝土混合结构的主要形式,包括型钢混凝土-钢结构竖向混合结构(SRC-S竖向混合结构)和型钢混凝土-钢筋混凝土土竖向混合结构(SRC-RC竖向混合结构)两种主要类型,在高层建筑中具有显著性能优势并且应用广泛。文章介绍了SRC-S竖向混合结构和SRC-RC竖向混合结构的受力特点和设计现状;针对我国和日本的相关规程及工程应用实践,结合日本阪神地震中SRC-RC竖向混合结构的主要震害特点,指出国内外SRC-RC竖向混合结构过渡层抗震设计方法所存在的主要问题及不足。在综合分析阪神地震后日本关于SRC-RC竖向混合结构过渡层抗震设计方法的最新研究进展的基础上,提出了SRC-RC竖向混合结构过渡层抗震设计的设计思路和方法。本文可为SRC-RC竖向混合结构过渡层抗震设计提供参考。

The steel reinforced concrete （SRC） vertical hybrid structure is another main type of steel-concrete hybrid structures, which is composed of the two typical types of steel reinforced concrete-steel vertical hybrid structures （SRC-S vertical hybrid structure） and steel reinforced concrete-reinforced concrete vertical hybrid structures （SRC-RC vertical hybrid structure）. The SRC vertical hybrid structures are widely used in the modern high-rising building. In this paper, the main characters of the SRC-S and SRC-RC vertical hybrid structures are introduced. Based on the engineering practices and the design codes in China and Japan, and together with the damage features of this type structures in 1995 Hyogoken-Nanbu earthquake in Japan, the shortages and problems of nowadays seismic design of the transmission story are analyzed in detail. And fully review of the experiment studies of Japan on the seismic performance of SRC-RC vertical hybrid structures, mostly on the seismic behavior of transition column are presented With summing up of the researches achievement in Japan after 1995, some advices and methods on seismic design of the transition story of vertical hybrid structures are finally presented.
