"Influence of the connection behaviour on the seismic resistance of multi-storey crosslam buildings"

The paper investigates the influence of modelling different types of connections in multi-storey crosslaminated (‘crosslam’) buildings when performing different types of analyses. More specifically, linear modal response spectrum analysis, nonlinear static (push-over) analysis assessed with a modified N2 method, and nonlinear time-history analysis are considered herein. In the research done by other authors, so far only the behaviour of certain types of crosslam building assemblies was investigated. In this paper it is shown how different connection details influence the building’s global ductility and peak ground acceleration. Basic values of overstrength factors for BMF 105 angular brackets and 8 mm self-tapping screws are also presented and the importance of using the overstrength concept in design is demonstrated on a case-study wall.
