Optimum Design of Reinforced Concrete Stairs Using Hill Climbing Algorithm
Keywords:
Optimum Design, Hill Climbing Algorithm, Reinforced Concrete Stair, Working Stress DesignAbstract
This research proposes the optimal design of reinforced concrete stairs using the Hill Climbing Algorithm. The stairs were designed by the working stress design method of the Engineering Institute of Thailand (EIT Standard 011007-19). The design calculated the size of the riser, the tread, the thickness of the waist slap, the optimum steel reinforcement, and the total price of reinforced concrete stairs from the construction material and labor cost. The experiment compared the Hill Climbing Algorithm and the conventional calculation method. The results showed that the use of the Hill Climbing Algorithm for the proper design of reinforced concrete stairs was better than conventional calculation methods. The Hill Climbing Algorithm resulted in a smaller thickness of waist slap with less steel reinforcement. As a result, the total price was lower than conventional calculation methods, representing an average of 4.81%. In addition, the Hill Climbing Algorithm can quickly design reinforced concrete stairs with suitable cross-sectional dimensions and reinforcing steel automatically and does not require the experience or expertise of the designer.
