摘要

A multi-storey timber-steel hybrid structure, which is composed of a steel frame and a light wood-frame shear wall, is introduced. Light wood-frame shear walls are used as infill between steel columns to form a timber-steel hybrid system to resist the lateral loads of the structure. In this paper, the lateral performance of a timber-steel hybrid structure is studied through pseudo static experiments. The dual characteristics of the steel frame and wood shear wall interactions are discussed. The effectiveness of infill light wood-frame shear walls in resisting lateral loads and their influence on the steel frame's behaviour are obtained from experiments of a single-storey specimen. At the same time, the strength, rigidity, hysteretic behaviour and failure modes of a timber-steel hybrid lateral resistant system are investigated. Experimental results show infill wood shear walls can work together with the steel frame, improving structural behaviour. The steel frame and wood shear wall roughly maintain their own lateral load bearing characteristics and show complementary behaviour in the hybrid system. This research aims to develop an environmental friendly prefabricated structural system and explores the application of timber in multi-storey buildings.
