LINEARLY ELASTIC ANALYSIS OF PLANE FRAMES SUBJECTED TO COMPLEX LOADING CONDITIONS

A LINEARLY ELASTIC SOLUTION FOR THE COMPUTER-AIDED ANALYSIS OF PLANE FRAMES IS PRESENTED. THE PROGRAM DEVELOPED FEATURES INPUT FORMATS WHICH GREATLY REDUCE THE USUAL PREPARATION OF DATA. THE SOLUTION USES A VARIATION OF THE BASIC DISCRETE ELEMENT BEAM-COLUMN MODEL FOR THE EVALUATION OF MEMBER STIFFNESS AND FINED-AND-FORCE PROPERTIES. THE MODEL ALLOWS FLEXURAL AND AXIAL RIGIDITY AS WELL AS LATERAL, AXIAL, AND ROTATIONAL VALUES OF LOADING AND ELASTIC RESTRAINT TO VARY RANDOMLY ALONG THE LENGTH OF THE MEMBER. INPUT IS NOT RESTRICTED TO VALUE LUMPED AT CERTAIN DISCRETE STATIONS, AND THE VALUES MAY BE TAKEN AT ANY POLE OF THE MEMBER. OPTIONS PROVIDED DO NOT REQUIRE THE TRANSFERRING OF LOADS AND DIMENSIONS FROM ONE AXIS TO ANOTHER BY THE USER. FRAME DISPLACEMENTS ARE OBTAINED BY STANDARD MATRIX TECHNIQUES MODIFIED TO UTILIZE THE TIME AND STORAGE REDUCTIONS FOR LINEARLY ELASTIC PLANE FRAMES. THE FRAME GEOMETRY MAY VARY RANDOMLY AND THE INPUT STILL CAN BE DONE SIMPLY. OPTIONS ARE PROVIDED TO PERMIT THE ANALYSIS OF A STRUCTURE FOR SEVERAL LOADING CASES AND COMBINATIONS OF CASES WITH A MINIMUM OF NEW INPUT AND COMPUTER TIME. /AUTHOR/
