A multi-hazard risk assessment of steel diagrid structures under non-concurrent seismic and wind loads was conducted. Initially, a motion-based design methodology was developed and validated for three configurations, which were analyzed with nonlinear techniques for obtaining their fragility curves as a function of their return periods and then assessed under three performance objectives. The results provide a useful risk management tool and it was found that the optimum angle and module are site-specific variables.
