Abstract:
The seismic response of 40 m span of K6 single-layer reticulated shell was analyzed in the conditions of multi-dimensional and multi-support excitations, and simple support excitation respectively based on the time history analysis method. The structural responses under the two forms of earthquake loads were compared. Piezoelectric intelligent bars were installed at the weak parts of the long-span space reticulated shell structures. The seismic response changes of the structures before and after the installation of piezoelectric intelligent bar were compared under multi-dimensional and multi-support excitations. The results show that multi-dimensional and multi-support excitations on long-span space reticulated shell structures will have more adverse impact than single support excitation and thus could be considered in design process. The seismic response of the majority bars reduce significantly after the structure installing the piezoelectric intelligent bars, which reach the effect of structure intelligent stable control.
