Analyzing the design of foundation reinforced concrete pile cap foundation by using plane and space strut and tie models and console beam modelfor theoretical and practical problems

This paper presents theoretical background and compares the calculation results of the design of reinforced concrete square pile cap foundation subjected to complex bearing conditions of the actual construction. The calculation results are obtained by using the plane strut and tie model (STM 2D), space strut and tie model (STM 3D) and console beam model. When the bearing reinforcement capacity of the pile foundation in the short side and the long side is examined, the results show that the actual design is greater than STM 2D, STM 3D and the console beam model from 17.95% to 29.03%. The results also demonstrate that the used STM 2D, STM 3D and console beam models and the design of pile cap foundations are accurate, appropriate, highly reliable, and effective in terms of both economic and technical aspects.
