TWO COLUMN RIGID FRAME PIER BENT

THE REPORT DESCRIBES 22 COMPUTER PROGRAMS DEVELOPED FOR THE ANALYSIS AND DESIGN OF TWO COLUMN RIGID FRAME PIERS FOR HIGHWAY BRIDGES. THE PROGRAMS WERE DEVELOPED IN THE FORTRAN PROGRAMING LANGUAGE FOR AN IBM 1620 DIGITAL COMPUTER WITH A BASIC STORAGE CAPACITY OF 20,000 UNITS. THE 22 PROGRAMS, EACH OF WHICH REQUIRE PRACTICALLY ALL STORAGE AVAILABLE, ARE COMPILED AND INTEGRATED TO FORM A SYSTEM BY CARRYING PERTINENT DATA FORWARD, FROM ONE PROGRAM TO ANOTHER. THE PROGRAMS DETERMINE MAXIMUM BENDING MOMENTS, SHEARS AND REACTIONS AT NUMEROUS POINTS ON THE STRUCTURES DUE TO LIVE LOAD, DEAD LOAD, WIND LOADS, AND LONGITUDINAL FORCES. THESE RESULTS ARE PRINTED ALONG WITH THE MAXIMUM COMBINATIONS OF MOMENTS AND SHEARS FOR LOADING GROUPS I, II AND III AS PROVIDED FOR IN THE AASHO SPECIFICATION. LONGITUDINAL STEEL AREAS, STIRRUP SIZES AND SPACINGS ARE COMPUTED. IN ADDITION, AN INFLUENCE LINE PROGRAM IS INCLUDED WHICH DETERMINES COEFFICIENTS FOR BENDING MOMENTS AT QUARTER POINTS OF A FOUR SPAN CONTINUOUS GIRDER. THE INFLUENCE LINE ORDINATES ARE DETERMINED FOR A UNIT LOAD APPLIED AT THE TENTH POINTS OF THE FOUR SPANS. /BPR/
