| Abstract: | Indicating matrix algorithm for double-layer lattice barrel vaults is a kind of mathematical system expressing the structural configuration with matrix forms. It introduces a set of representation of node and element information, accomplishes node and element numbering automatically, and forms the data structures describing the node, element, boundary condition, and load vector and so on. It is suitable to different kinds of double-layer lattice barrel vaults and simplifies the pre-processing of computer aided analysis. |
