The　performance-based　design　is　the　development　trend　of　seismic　design.　Based　on　the　research　topics　and　development　trends　of　performance-based　seismic　design,　the　state-of-the-art　of　performance-based　seismic　design　for　spatial　structures　is　provided,　with　subjects　on　seismic　hazard　analysis,　structural　response　analysis,　classification　of　performance　levels　and　determination　of　performance　objectives,　performance-based　seismic　design　methodology.　Scalar,　vector　and　other　type　of　ground　motion　parameters　for　various　types　of　spatial　structures　should　be　determined　by　efficiency　and　sufficiency　principles,　and　the　key　issues　in　the　research　of　seismic　behavior　of　spatial　structures　are　presented.　In　classifying　the　seismic　performance　levels　of　spatial　structures,　the　structural　and　non-structural　elements　should　be　considered,　and　the　numerical　simulation　and　experimental　methods　should　be　used　to　determine　the　user-defined　comprehensive　index,　vector-valued　index　or　the　index　combining　these　two　forms.　The　selection　of　performance　objectives　and　the　design　methodology　research　should　be　based　on　the　reliability　theory　and　cost-effectiveness　criterion.
