Abstract

Today, development of middle or high-rise timber buildings is a relevant response to environmental issues and urban densification. Testing on such structures, in order to understand their behavior, is still hardly possible in real size. The solution we propose to study is, to experiment a reduced structure, and using similitude laws, to deduce the real size structure’s behavior. We propose to present in this communication, a literature review with some applications. State of the art shows that similitude laws theory initially developed in aerospace and aeronautics, and then exploited in civil engineering, is almost absent in timber, which brings specific issues. Several methods make it possible to constitute similitude laws. We will establish similitude laws for a middle-rise timber (R+4; R+5). The reduced prototype’s design will be carried out on different scales: joint’s scale and structure’s scale, in conjunction with regulatory standards.
