All manuscripts will be blindly peer-reviewed by two reviewers. If a manuscript is adjudged suitable, it will be published as either a Research Paper, Review Paper or a Technical Note. The journal is published biannually in June and December.

The design consideration is based on the provision of BS8110 separating the slab into middle and column strips. The optimisation is to find the optimum slab thickness with least cost. The use of the in-built genetic algorithm function of MATLAB software was employed to minimise the design at various steel ratios. The constraints applied were non-linear and thus required a lengthy iteration cycles before convergence. The objective function for either strip is treated separately without any coupling in line with the design philosophy of BS8110. The optimum thicknesses for the middle and column strips are 130mm and 140mm respectively. The reinforcement ratios for the optimum design were also established to be 2% and 3.5% for the middle and column strips respectively.
