Abstract

Single nailed batten to rafter connections of non-cyclonic region houses were tested under quasi-static ramp loads and under fluctuating dynamic loads determined from a wind tunnel study. Dynamic connection testing showed that nails of connections slip during intermittent 'peak events' in the wind load time history with connection failure occurring after several peak events. Non-linear time-history structural analysis was performed on a system of batten to rafter connections where connection testing data were used to model the nominal force-displacement relationships of the nailed connections. This preliminary computer analysis was able to capture the effects of load sharing and redistribution during nail slips and progressive failures.
