File name is SHAFT 1. This is a time sharing program which analyzes a spirally reinforced, circular concrete drilled shaft. No other geometric patterns are permitted. Working stress design is used. A design approach can be used by utilizing a what-if concept. Program computes section properties, and performs a column and footing analysis. User builds a data file from keyboard input; input consists of bridge number, location, bent numbers, shaft diameter, number of reinforcing bars, bar size, distances from top of shaft to column analysis point and bottom of footing, axial loads and moments. Teletypewriter output consists of bridge number, location, bent numbers, section properties, column analysis (eccentricity ratios, allowable and equivalent axial equivalent axial loads, combined and allowable fiber stresses), and footing analysis (tons per square foot for shaft alone plus three belled footings using six inch increments). Program will abort if any A.R.E.A. allowables are exceeded. See A.R.E.A. manual, Chapter 8. Program actually performs a double analysis, one for primary loading (live load, dead load, centrifugal force) and the other for secondary forces added (other lateral plus longitudinal forces). Under primary loading with secondary loading added, allowables are increased 25%.
