Topology design of optimizing material arrangements of

This study presents conceptually effective layouts of materials, i.e. steel or fiber, optimallypositioned into building frames. the design information of the material layout may be helpful in dealingwith large-scale safety design issues in civil or architectural engineering fields, against natural phenomena,such as winds and earthquakes. the material topology optimization method evaluates an optimal layoutreinforcing or arranging material of a specified volume in a given design space that maximizes stiffnessfor a given set of loads and boundary conditions. generating the optimal distribution of material is similarto the so-called strut-and-tie method using truss members of straight lines, and it leads to the stiffeststructures. numerical applications verify that the present material topology optimization method is anapplicable concept design tool to create effective layout designs of material in given structural frames incivil and building industries.
