摘要: Abstract Ductile fracture preceding brittle was observed in welded steel moment resisting frames during past strong earthquakes. Studies on ductile were mainly focused steels under normal stress loading, while seldom for those combined shear and which is also a common state structural components, e.g., fillet joints partial penetration joints. of tension has been investigated through monotonic experiments previous study, this paper aims to clarify the corresponding cyclic loading cases. Two series specimens are manufactured, where they respectively pure shear, loading. Meanwhile, coupled model considering material deterioration proposed simulate both crack initiation propagation, method simply obtain parameter propagation rule validated comparison between experimental numerical results.
