Abstract

Internal forces and displacement caused from the thermal effects can be important for structures that can be subject to large temperature changes. For that reason, determining these effects accurately during the design process is essential for security of structural systems. In this paper, a methodology called total potential optimization using metaheuristic algorithms (TPO/MA) that has been successfully applied for analyzing different types of systems such as truss, cables and tensegrity structures, is presented for investigation of analyses of truss structures considering thermal effects. Teaching learning based optimization (TLBO) algorithm is employed as metaheuristic approach. Results are compared with other methods that used wellknown metaheuristic approach harmony search (HS) and finite element method (FEM). According to results, proposed approach is accurate, robust and reliable for the analyses of this kind of problem.
