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 COMPUTER PROGRAM FEATURES INPUT FORMATS WHICH GREATLY REDUCE THE MANUAL PREPARATION OF DATA. THE SOLUTION USES A VARIATION OF THE BASIC DISCRETE-ELEMENT BEAM-COLUMN MODEL FOR THE EVALUATION OF MEMBER STIFFNESS AND FIXED-END-FORCE PROPERTIES. THE NEW DISCRETE-ELEMENT 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 MEMBERS. INPUT IS NOT RESTRICTED TO VALUES LUMPED AT CERTAIN DISCRETE STATIONS BUT MAY BE INPUT IN NORMAL ENGINEERING VALUES AT ANY POINT ON THE MEMBER. IN ADDITION, 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 POSSIBLE FOR LINEARLY ELASTIC PLANE FRAMES. THE FRAME GEOMETRY MAY VARY RANDOMLY AND STILL BE INPUT IN A SIMPLE AND STRAIGHTFORWARD MANNER. 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/
