A Simplified Numerical Modelling Approach for the Nonlinear Analysis of Reinforced Concrete Structures

Reinforced concrete (RC) is a widely preferred material for all types of infrastructure. A few of the main advantages of RC are its durability and economical availability but at the same time its non-homogenous behavior makes it difficult to analyze especially in the cases where non-linear behavior of the structure is to be accessed. This paper presents a simplified numerical model tailored for the nonlinear analysis of reinforced concrete structures, emphasizing enhanced efficiency and accuracy. Integrating material science insights and advanced computational techniques, our model encompasses crucial nonlinearities, including material behavior and geometric variations. Notably, our model's versatility extends to its seamless integration with commercially available structural design software such as ETABS and SAP2000, eliminating the need for complex Finite Element Modeling tools like ABAQUS. Validation against experimental data and comparison with existing models substantiate its reliability and effectiveness. Our model not only streamlines analysis procedures but also furnishes actionable insights for optimizing the design and performance of reinforced concrete structures in practical applications.
