Predictive Model of Moment of Resistance for Rectangular Reinforced Concrete Section under Actions

Abstract

Generally engineering design requires adequate data, good understanding of methods of analysis and ability to use them effectively and accurately for creative processes. A model is developed for predicting implications of various combinations of sectional dimensions in structural reinforced concrete elements. The method adopted is purely mathematical technique of modeling, concept and application.

The paper thus aimed at increasing design understanding for effectiveness and precision to ensure safety in structural design. A concrete rectangular section of singly reinforced status was used as a case study. The section was analyzed from stress-strain relationship to formulate the governing equation.  This was simulated to describe the relationship between the variable parameters and predict the behavior of a rectangular section under loads. The section is specified by breadth b, total depth h and moment of resistance M_R. Thus the adequate sectional dimension can be accurately selected for design.
