Seismic Optimum Design for the High-Rise Building with Girder Transfer Floor

Abstract eng:
This paper proposes an integrated seismic optimum design approach for the high-rise buildings with girder transfer floor, including topology optimum design of the transfer floor and size optimum design of beams and columns. First, the girder transfer floor is optimized using the SIMP topology optimization method to obtain the optimum topological form of the transfer floor. Then the size optimum design of beams and columns is performed. The initial cost and life cycle cost are employed as the objective function in the seismic design, respectively. Finally, a numerical example of 23-story high-rise building is calculated, and the results show the optimum design of minimum life cycle cost is more cost-effective.
