Abstract:This paper presents a stress analysis of partially prestressed arbitrary concrete sections with mixed reinforcement consisting of a combination of prestressed and nonprestressed reinforcement with individual mechanical properties under axial load and biaxial bending in the serviceability limit state. The same problem has been treated in a previous paper, where the analysis was adjusted to enable calculation by means of low capacity calculators. The advantages of the present version are partly that it enables direct input and adjustment of the basic parameters and partly that it covers triangular, trapezoidal, and pentagonal compression zones with automatic transitions from any one zone to another. These advantages were obtained by increasing the calculator capacity requirement although still not exceeding the capacity of existing hand-held calculators. The ultimate limit state problem corresponding to the present serviceability limit state analysis has been treated in two previous papers.
