A Proposal for Classification of Wooden Houses Based on Seismic Performance and Calculation Method of Standard Load-Deformation Relationship

Abstract

Damage assumptions have been made in response to major earthquakes such as the Nankai Trough earthquake, but most of them only take into account the type of structure and the age of the building. On the other hand, it has been pointed out that earthquake damage is affected by the presence or absence of joint hardware and eccentricity. In this study, we classify wooden houses according to factors of seismic performance such as construction method, number of floors, weight, wall quantity, seismic elements, joints, eccentricity, and horizontal diaphragm, and show examples of calculation of standard load-deformation relationships according to these classifications and basic data.
