: This report describes the mathematical model and the solution process which form the basis of the computer program SINGER. The function of SINGER is to predict the behavior of plane skeletal reinforced concrete structures in their environments. Of primary interest is the transient nonlinear response including element failures and structural collapse. The structure is represented by a discrete model composed of line elements (models of partial joint releases). The line elements admit geometric and physical nonlinearities; they can predict the behavior of reinforced concrete members subject to axial and flexural distortions up to failure. The state of the element is characterized by its internal energy.

SINGER: A Computer Code for General Analysis of Two-Dimensional Reinforced Concrete Structures. Volume 1. Solution Process

PRESENTS AN ELASTIC STRESS ANALYSIS FOR RECTANGULAR REINFORCED CONCRETE CURVED BEAMS WITH CIRCULAR AXES SUBJECT TO PURE BENDING. THE ANALYSIS DEALS WITH RECTANGULAR SECTIONS REINFORCED ON THE TENSION SIDE ONLY. THE LOCATION OF THE NEUTRAL AXIS AND THE CALCULATION OF MAXIMUM STRESSES IN CONCRETE AND STEEL IS GIVEN IN CHART FORM. THE LIMITING CASE FOR BEAMS WITH STRAIGHT AXES IS ALSO PRESENTED FOR COMPARISON. IF THE RADIUS OF CURVATURE OF THE MEMBER IS SMALL COMPARED TO THE BEAM DEPTH, THE STRESSES DIFFER SIGNIFICANTLY FROM CALCULATED USING LINEAR BEAM THEORY. /AUTHOR/
