A DIRECT COMPUTER SOLUTION FOR PLANE FRAMES

A DIRECT METHOD OF SOLUTION FOR THE COMPUTER ANALYSIS OF PLANE FRAME STRUCTURES IS PRESENTED. THE METHOD COMBINES THE DISCRETE-ELEMENT BEAM-COLUMN MODEL FOR THE EVALUATION OF STIFFNESS TERMS FOR NONPRISMATIC MEMBERS WITH THE DIRECT SOLUTION TECHNIQUES OF CONVENTIONAL FRAME ANALYSIS. FLEXURAL PROPERTIES, LOADS, AND ELASTIC SPRING RESTRAINTS ARE ALLOWED TO VARY AT WILL ALONG ANY MEMBER. THE METHOD IS NOT RESTRICTED TO ORTHOGONAL FRAMEWORKS. NO RESTRICTIONS ARE PLACED ON THE MODE OF DEFORMATION OF THE FRAME. THE EFFECT OF AXIAL DEFORMATIONS ON FRAME BEHAVIOR IS CONSIDERED AND THE INVESTIGATION OF THE EFFECTS OF AXIAL THRUST ON BENDING STIFFNESS IS ALLOWED. A REDUCTION IN INPUT IS ACHIEVED BY A GRID TYPE DESCRIPTION OF THE FRAME. SEVERAL EXAMPLE SOLUTIONS ARE PRESENTED. /AUTHOR/
