OPTIMAL ALLOCATION OF SHARE-WALL BY BRANCH-AND-BOUND METHOD
|
´˜^i‰pjF
The allocation problem of shear-walls can be described as a combinatorial optimality of both torsional rigidity and wall weight under constraints from architectural, structural and constructional aspects. This study deal with application of the branch-and-bound method with binary-branching operation to optimal allocation of shear-walls in 3D frames against twisting about a vertical axis. Concerned with effectivity of search for optimal solutions, the present optimality criteria is compared to our previous work[1] which is applied the branch-and-bound method with multi-branching operation.
