| Abstract: | Based on the method for imperfection analysis just as used in the analysis of static stability, the effect of initial imperfection on the large displacement stability behavior of two well-known types of single layer reticulated domes subjected to dynamic loads is examined in this paper. Three types of time-dependent loading cases are considered in the analyses,namely,step load of infinite duration sinusoidal load of infinite duration and triangular impulsive load. |

| Keywords: | initial imperfection reticulated structures dynamic stability analysis. |
