An optimal design method is presented for large-span structures subjected to spatially varying ground motions. The maximum response strains of the members considering the static and dynamic components are evaluated by using a response spectrum method which is verified by carrying out time history analysis for spectrum-compatible seismic motions. Optimum design problem is formulated for finding optimal cross-sectional areas of a structure with fixed geometry so as to minimize the total structural volume under strain constraints, where the wave passage effect, incoherence effect and local effect are considered. It is shown in the examples that the difference in support motions significantly influences the seismic responses and optimum cross-sectional areas of large-span trusses.
