Abstract

The computational efficiency of a full-structure model for a light-frame building is enhanced by replacing the continuum of the detailed connections with rotational and translational nonlinear springs that are energetically equivalent between two bounds. This study examines the transformation from the physical exterior-wall-to-exterior-wall connection (a corner) of a light-frame wood structure, first, to a two-dimensional finite-element model and, then, to a set of nonlinear springs. Typical light-frame details are used as the starting point, and the product is the characteristic moment-rotation and load-displacement relationships for a 24-inch segment of the corner.
