速成墙结构技术的发展和开发

Development of the structural design theory for rapidwall~ building system

介绍一种由澳洲最新研发的建筑材料和相应的结构体系———速成墙结构体系的发展简史和澳洲的速成墙设计理论及其研究成果。先介绍和论述速成墙结构早期的抗震设计理念和设计方法。然后介绍速成墙研究的最新实验和理论进展以及在此基础上的新设计理论。并着重介绍速成墙独特的剪切破坏模式———纵向剪切破坏,分析和推导与该破坏模式对应的抗剪设计理论和设计方法。

A new building material and the corresponding building system - Rapidwallbuilding system, which is recently developed in Australia, is introduced in this paper. Rapidwall itself is a glass-fiber reinforced gypsum hollow walling panel. The combination of Rapidwallwith concrete and/or other building materials forms a new type of structural system. The major advantage of this new building g system is lightweight, fast and effective construction process, and energy effective and eco-friendly. This building system has been successfully applied in Australian building industry, and recently been introduced into China. Its advantages have already attracted a lot of interests from academics and construction industry. The development of the new building system is briefed. The structural design theory and the research works in Australia are introduced. The old seismic design concept and theory is firstly introduced, followed by the recent experimental and theoretical research development which formed the foundation of the new structural design guidelines for Rapidwall building system. Focus was placed on the unique shear failure mode of Rapidwall panels - longitudinal shear failure. The shear strength corresponding to this failure mode and the design methodology is derived and presented in the paper.
