A COMPUTER PROGRAM TO ANALYZE BEAM-COLUMNS UNDER MOVABLE LOADS

A COMPUTER PROGRAM IS PRESENTED WHICH CAN EFFICIENTLY ANALYZE A BEAM-COLUMN SUBJECTED TO MOVABLE STATIC LOADS. THE PROGRAM IS BUILT AROUND THE COMPUTER SIMULATION OF A BEAM- COLUMN SUBJECTED TO STATIONARY LOADS WHICH IS DESCRIBED IN A PREVIOUS REPORT. THE METHODS USED IN THE PROGRAM ARE SUCH THAT A BEAM-COLUMN CAN BE ANALYZED FOR ANY PATTERN OF TRANSVERSE LOADS THAT MOVE ACROSS THE MEMBER. THESE LOAD PATTERNS MAY BE ANY DIVERSE SYSTEM OF LOADINGS SUCH AS A HIGHWAY TRUCK, A SERIES OF TRUCKS, OR POSSIBLY A TRAIN ON A RAILROAD STRUCTURE. IN ADDITION, THE EFFECTS OF FIXED LOADS CAN BE INCLUDED IN THE ANALYSIS. FURTHERMORE, THE EFFECTS OF VARIOUS CHANGES IN THE SUPPORT HISTORY /SUCH AS SETTLEMENT OF A SUPPORT/ CAN BE STUDIED. THE RESULTS OF AN ANALYSIS MAY INCLUDE /1/ SOLUTIONS FOR THE MEMBER UNDER FIXED LOADS, /2/ INFLUENCE DIAGRAMS FOR MOVABLE-LOAD PATTERNS, AND /3/ ENVELOPES OF MAXIMUM VALUES OF DEFLECTION BENDING MOMENT, SHEAR, AND SUPPORT REACTION THAT OCCUR DUE TO THE LOADING AND SUPPORT HISTORY. FIVE EXAMPLE PROBLEMS THAT ARE TYPICAL OF THOSE ENCOUNTERED BY HIGHWAY STRUCTURAL DESIGNERS ILLUSTRATE THE USES OF THE PROGRAM AND THE OPTIONS AVAILABLE. /AUTHOR/
