Abstract. In the optimization process where metaheuristic methods are used, large number of structural analysis
is needed due to the nature of the methods. The most popular method used in structural analysis in civil
engineering is the finite element displacement method. In the displacement method, after the global stiffness matrix
is created, first the nodal displacements and then the internal forces of the elements are calculated. And these steps
are repeated in each iteration, depending on the optimization method used, and naturally requires longer time for
the analysis. Especially in structural systems with large number of elements, reducing analysis times can be an
advantageous. In order to benefit from this advantage, choosing different structural analysis methods appears as
an alternative. In this context, the performance of metaheuristic optimization methods combined with Integrated
Force Method for structural analysis have been investigated. In the Integrated Force Method, first the internal
forces of the elements and then the displacements of the nodes are calculated. Displacement method and Integrated
Force Method are compared in terms of section optimization based on Harmony Search Algorithm and Teaching
Learning Based Optimization. The obtained data show that the CPU times spent in the optimization processes
using Integrated Force Method are shorter than the times spent in the case of Displacement Method.
