## What is/are Single Layer Spherical?

Single Layer Spherical - The frequency band from 8 to 30 Hz was analyzed; for all spectral components in this band, the inverse problem was solved in the approximation of an equivalent current dipole in a single-layer spherical conductor, without any restrictions on the position of the source.^{[1]}In order to study the impact resistance performance of reticulated shell under multi-point impact load, the multi-point elastic-plastic impact and destructive impact test of Kiewitt 6 (K6) single-layer spherical reticulated shell are carried out.

^{[2]}Secondly, a one-story thin-walled steel framework, a five-story thin-walled steel framework and a single-layer spherical reticulated shell separately subjected to different waves were selected on which to carry out the nonlinear time-history response analysis to obtain the ESED model to verify the new failure criterion.

^{[3]}This paper aims to provide an aerodynamic optimization procedure to improve the aerodynamic performance of single-layer spherical domes, by coupling the kriging surrogate model with computational fluid dynamics (CFD) and finite element analysis (FEA).

^{[4]}The purpose of the study is to work out the dynamic response of the discrete single-layer spherical domes.

## reticulated shell structure

In this paper, the “battery” program was compiled based on the parametric tool Rhino+Grasshopper and the parameterized modeling function of K-type single-layer spherical reticulated shell structure was realized.^{[1]}The finite element model of Kiewitt8 single-layer spherical reticulated shell structure is established in ANSYS.

^{[2]}To study the dynamic response characteristics and failure process of single-layer spherical reticulated shells under impact loads at different loading points, impact dynamic analysis and experimental study are conducted on the K6 single-layer reticulated shell structure.
