Cost Analysis of the Reinforced Concrete Frame Structure Design with All Parameters Full Constraints Optimization

Parameters of present optimization design were usually simplified to one-dimensional or multidimensional,sometimes constraint conditions were inadequate,though it was all parameters optimization design.Against these deficiencies,a mathematical model of all parameters full constraints optimization of reinforced concrete frame structure design was established in this paper.Then fmincon function in MATLAB was used for optimization calculation,it can be connected with various structure design software to carry on parameter optimization,such as the calculating example in this paper was connected with the force compute function contained in the software PKPM which developed by China Architecture Design and Research Group.Finally,we compared and analyzed the influence to the cost among each parameter in our calculating example,got qualitative and quantitative conclusion.The cost of the building had a great reduce after the optimization.Compared with the current optimization of reinforced concrete frame structure design,this paper had more practical and more efficient optimization algorithm.
