| Abstract | ||
| This paper presents an analytical method which takes into account the non-linearity of individualrnmembers, and discusses some case study results. It also discusses the relationship between member non-elasticrnbehavior and excitation duration, and the relationship between member fracture and overall structurernbehavior. It is clearly demonstrated that the frame already shows almost unstable behavior due to long-columnizationrnjust before the occurrence of a column fracture. Then, a column fracture immediately induces arnstructural collapse mechanism. | ||
