摘要：
Here, to analyze soil-strueture interaction (SSI) and seismic response of single-layer reticulated dome under oblique incidence seismic wave, equivalent nodal forces were used to realize seismic wave input. Infinity radiation condition was processed using viscoelastic artificial boundary. Effects of seismic wave type, soil parameters, incidence angle, and other factors on SSI and seismic response of single-layer reticulated dome were analyzed. The results showed that single-layer reticulated dome structure has upwarping on incident side of seismic wave, and the overall shell rotates along incident direction; when primary wave (P-wave) is obliquely incident, the maximum displacement difference between supports is 0. 514 m, it is 1/250 of shell span; when P-wave is obliquely incident, top displacement of the shell in soft soil is larger than that in medium-hard soil and medium-soft soil, and shell top displacement firstly increases and then decreases with increase in incident angle; when SV wave is incident, shell top displacement in medium-soft soil is larger than that in medium-hard soil and soft soil, and shell top displacement increases with increase in incident angle; under oblique incident seismic wave, after considering SSI, the maximum increase in shell top displacement reaches 5. 5 times, increases in displacements at shell outer ring are larger than those at shell mid-span. © 2024 Chinese Vibration Engineering Society.
