The case study investigated is an industrial wood-framed warehouse with two-hinged frames where the post-beam connections are semi-rigid moment-resisting joints with dowel-type fasteners. A necessary condition for applying DBD is that it be possible to estimate a priori (i) the target displacement of the portal and (ii) the equivalent damping ratio of the structure at the ultimate capacity. The general assumption is that the displacement capacity of the building mainly depends on single joint behavior and only to a smaller extent on the size of structural members. This observation lets us define a practical expression for calculation of the target displacement with only the dimensions of members and connections. Using pushover non-linear analyses, we demonstrated that the expression provides prior values of target displacement that are close to those obtained a posteriori using a much more refined model that takes account of the exact geometry of members and connections. The comparison with the results of Eurocode 8 shows that the DBD method potentially can overcome some of the simplifications that a Force Based Design (FBD) method necessarily leads to.
