摘要：
An optimization method is proposed for stiffness design of RC columns of a school gymnasium to reduce the interaction forces at bearings between the steel roof and supporting structure under seismic motions. The objective function is the maximum force at the connections, which is evaluated using the response spectrum approach. Constraints are given for the total weight and the interstory drift angles of columns. The sizes of columns are optimized using simulated annealing. It is shown in the numerical examples that the maximum interaction force is drastically reduced to about half of the reference model through optimization. © 2020 Architectural Institute of Japan.
