Description
The guidance here is to clarify critical structural issues in carrying out bracing design, especially seismic design, of hillside light timber frame (LTF) houses, and to develop a rational bracing design method for hillside LTF houses. The guidance was developed based on the current NZBC and the current New Zealand Design Standard AS/NZS1170.
Scope
This guidance provides the fundamental philosophy for carrying out rational bracing design, particularly EQ design, of hillside LTF houses where significant stiffness incompatibility exists. The principles presented can be also applied to other situations where significant stiffness/deformation incompatibility exists. In many ways the guidance only contains qualitative principles. Detailed information on the force-deformation capacity of any particular systems is not provided in this because of the huge variations in the used systems and in the application situations.
