title = "A 3D model for collapse analysis of soft-story light-frame wood buildings",
abstract = "This paper presents the development of a new three-dimensional (3D) numerical model, developed as part of the NEES-Soft project, which is capable of modelling the collapse mechanism of 3D light-frame wood buildings under earthquake motions. In the new 3D model, the in-plane and out-of-plane flexibilities of floor and roof diaphragms are characterized using two-node 12 degrees-of-freedom (DOF) frame elements with corotation formulation and the shear walls are modelled using two-node 6-DOF link elements. To reduce the computational overhead of the model, a novel condensation technique using shape functions is employed to condense the DOFs of the link elements. This 3D model has been used to perform incremental dynamic analyses (IDA) for a three-story building with tuck-under parking garage in the first floor. The IDA results revealed that the building is prone to side-sway collapse in the first-story.",
