【Abstract】 Ecological composite wall is the main bearing member and lateral resistant system of ecological composite wall structure.It is important to find the reasonable designs of the ecological composite wall having lowest cost and satisfying the limitations and specifications of the code for ecological composite wall structure.The aim of this research is to design the minimum-cost ecological composite wall by the method of Genetic Algorithm.The optimum model is put forward,and a computer program based on Genetic Algorithm is also developed for determining the optimum values for the minimum-cost design of the ecological composite wall.Finally,a design example is presented demonstrating the efficiency of the procedure for the wall.Theoretical analysis and calculated results show that applying Genetic Algorithm to the cost optimization of the ecological composite wall with different geometric specifications and filler material is effective,practicable,and very meaningful to the practical engineering.At the same time,it opens up a new way for the optimization design of the ecological composite wall structure.更多还原
