Optimal Detailed Design of RC Frame Using Improved Ray Optimisation

In the current research, optimisation of the RC frames is carried out using a meta-heuristic technique called Improved Ray Optimisation. The optimisation program developed is automated using various computer applications. It is a recently developed optimisation technique and therefore, not much work is available on its application on RC framed structures. The objective function is to minimise the overall cost of the RC frames. Various computer applications have been used for preparing and automating the optimisation program for RC structures. Optimisation is done on two structural components of RC frame, i.e. beams and columns and the cost of both are calculated. The calculation of the cost of RC structure includes cost of steel, cost of concrete and cost of formwork. The optimisation program so developed is written in MATLAB application. The results of a model from a literature are compared with the results of the optimisation program. The results are quiet encouraging and show the effectiveness of the current optimisation program. The optimisation program is checked for dependencies like the effect of number of iterations and number of agents on finding the optimal cost of RC frame and influence of the search space on the strength of the RC structure.
