_____________________________________________________________________________________ _____________________________________________________________________________________ HINT: ------ SAGGING CABLE IS VERY SENSITIVE TO NUMERICAL ALGORITHM FOR CONVERSION. THE NUMERICAL ALGORITHM IS PARTIALLY COMPUTER HARDWARE AND SYSTEM SOFTWARE DEPENDENT. FOLLOWINGS ARE SUGGESTED FOR BETTER CONVERSION IF CONVERSION BECOMES A PROBLEM. 1) USE ELEMENT BEAM AND JOINT LOADS. (NO MEMBER LOADS) 2) IF A SAGGING CABLE IS A 2-D STRUCTURE, MAKE IT 2-D BY FIXING THE 3RD DIRECTION. 3) AVOID AN UNSTABLE JOINT CONFIGURATION TO START. FOR EXAMPLE: 3-1) COLINEAR JOINT - A JOINT AT WHICH TWO ELEMENTS MEET IN A STRAIGHT LINE. 3-2) COPLANAR JOINT - A JOINT AT WHICH ALL ELEMENTS MEET IN A COMMON PLANE. DIP THE JOINT DOWN SLIGHTLY, AND USE THE L-S COMMAND FOR ELEMENT TRUSS AND ELEMENT ONE-WAY. ( SEE INPUT GUIDE FOR ITS USE) 4) ADJUST THE TOLERANCE AS INDICATED IN KEYUSP.DAT
