Structural design generally involves hundreds of design variables and multiple constraints in practical engineering projects, nevertheless, traditional optimization techniques are failed to meet the engineering requirements for solving the optimization problem with high efficiency and accuracy. In this paper, a single driven constraint optimization method based on constraint sensitivity is presented for high-rise steel structure. The design method takes the sensitivity coefficient as the reference index for the optimization design of components to ensure proper compliance and redundancy requirements. An effective incremental analysis method is applied for the calculation of sensitivity coefficients within constraints and design variables. Sensitivity coefficients based material redistribution of components is carried out to make the structure achieve the optimization objective on the premise of satisfying all the design constraints. |
