Abstract

Load sharing and structural response of contemporary representative houses to loading are investigated using numerical model analysis and full scale test in this study. The structural system of the contemporary representative house is obtained from a field survey by Cyclone Testing Station, James Cook University. In Australia, Contemporary houses are generally brick veneer structures with metal or tile clad roofs. Previous studies on damage to timber framed houses show that the roof structure of a house is vulnerable to windstorms. This indicates the need to study their structural response to mitigate their failures in windstorms. The roof to wall connection is an important inter-component connection for the structural stability of a house during strong winds, by providing a continuous load path from the roof to the foundation. The aim of this study is to assess the loading effects on roof to wall connection of a typical brick veneer contemporary house. A numerical model of the contemporary representative house was developed which provides load sharing and the structural response. This result also shows that the structural system stability will improve with elements such as ceiling and ceiling cornice sharing the load. Full scale tests will be carried out and the numerical model will be validated from the full scale test results. Full scale tests carried out on the bare truss frames gives results that agree with the numerical model analysis.
