| Abstract: |
A shape optimization approach is presented for latticed blocks that are assembled as a wall used for seismic retrofit of building frames. The existing beams and columns, as well as the members in blocks, are modeled using beam elements. The negative effect on the existing beams and columns, such as increase of shear and axial forces due to installation of the blocks, are reduced by optimizing the thickness and location of members in the blocks. It is shown that various shapes can be generated by solving nonlinear programming problems considering structural weight, stiffness, and contact force against the existing frame members. |
