In recent years

near fault ground motions were found in several large earthquakes

causing severe damage to many structures. However

the analysis of structures subjected to near fault ground motions was mostly about bridges

and few relevant studies were conducted to single layer reticulated shells. To identify ground motion intensity measures for use in the seismic response evaluation of single-layer reticulated shells

three single-layer spherical reticulated shells with different rise-span ratio and five single-layer cylindrical reticulated shells with different risespan ratio or l

ength-width ratio were designed. Then to have a better understanding of their dynamic features

both modal analysis and harmonic response analysis were conducted to them. After that

several commonly used ground motion intensity measures were evaluated in terms of correlation

efficiency

and sufficiency. Results show that for any particular ground motion intensity measure

the measure along the span has stronger correlation compared with that in the vertical direction

when single-layer spherical reticulated shells were set as models; and that values of acceleration response spectra S

when single-layer cylindrical reticulated shells were set as models

for any particular ground motion intensity measure

the measure along the span has stronger correlation compared with those in the vertical direction and the direction along the length; and the value the value of acceleration response spectra S

the basic period T

otherwise the second or third natural period（T
