Abstract
This study is entitled as “Sub Structure Optimization for High Rise Building using Brute Force
Optimization”, and includes the concept of two different streams i.e. Optimization and Design of
Concrete Sub-Structure.
Previous researches such as “Optimum Design of Pile Foundation by Automatic Grouping
Genetic Algorithms” by Xiaofeng Liu, Gengdong Cheng et al. optimized pile and pile cap
separately, by first optimizing the piles and then designing a pile cap for the optimal pile design,
however this does not consider the effect of piles in the optimization of the pile cap. This thesis
employed Brute Force Optimization to optimize pile and pile cap simultaneously and take into
account the effect of piles in the optimization of the pile cap.
For the optimization formulation of the foundation types, the desired variable chosen for pile cap
are the depth, length and width of the pile cap, while for Pile foundation the desired variables
chosen are the number of piles in the X, the number of piles in the Y, the diameter of the pile, the
height of the pile and the depth of the pile cap. These variables will help minimize or optimize
the objective function by reducing the cost of material and excavation. The foundations will be
designed based on EC7.
A computer program using Java is developed to design an optimum foundation design for any
particular case within the scope of this study. The optimized design is checked using hand
calculation by simple example to determine its correctness and accuracy.
