STUDY ON A DEVELOPMENT OF TIMBER-STEEL HYBRID BEAM STRING STRUCTURE WITH LUMBER IN MORI-MACHI, HOKKAIDO

This study is to propose a timber-steel hybrid beam string structure with local lumbers of general distribution. The proposed system is that local constructors can handle locally grown lumber without special materials or techniques. We obtained the structural performance of this unique construction method through bending experimental tests of individual assembled upper-string members and structural tests and structural analysis of the timber-steel hybrid beam string structure. Findings through this study include the following：
