FAILURE PATTERNS OF KIEWITT8 SINGLE-LAYER RETICULATED DOMES UNDER IMPACT LOADS

This paper introduces briefly the analytical methods and numerical methods to solve non-linear problems, and then ANSYS/LS-DYNA, a finite element software. In order to validate the function of software and the parameter selection, solutions of a simple problem are obtained by the analytical method and ANSYS/LS-DYNA respectively, and good agreement is achieved. Finally, the model of Kiewitt8 single-layer reticulated dome with a span of 60m is set up, and 135 cases are analyzed, with five failure patterns observed.
