ANALYSIS OF CONTINUOUS FRAMES BY DISTRIBUTING FIXED-END MOMENTS

A METHOD IS EXPLAINED WHICH HAS BEEN FOUND USEFUL IN ANALYZING BRIDGE FRAMES WHICH ARE STATICALLY INDETERMINATE. THE ESSENTIAL IDEA INVOLVES NO MATHEMATICAL RELATIONS EXCEPT THE SIMPLEST ARITHMETIC. IT IS TRUE THAT IN ORDER TO APPLY THE METHOD IT IS NECESSARY TO DETERMINE CERTAIN CONSTANTS MATHEMATICALLY, BUT THE MEANS TO BE USED IN DETERMINING THESE CONSTANTS ARE NOT DISCUSSED IN THE PAPER, NOR ARE THEY PART OF THE METHOD. THESE CONSTANTS HAVE BEEN DERIVED BY SO MANY WRITERS AND IN SO MANY SLIGHTLY DIFFERENT WAYS THAT THERE IS LITTLE NEED TO REPEAT THE WHOLE PROCEDURE. THE REACTIONS IN BEAMS, BENTS AND ARCHES WHICH ARE IMMOVABLY FIXED AT THEIR ENDS HAVE BEEN EXTENSIVELY DISCUSSED. THEY CAN BE FOUND COMPARATIVELY READILY BY METHODS WHICH ARE MORE OR LESS STANDARD. THE METHOD OF ANALYSIS HEREIN PRESENTED ENABLES ONE TO DERIVE FROM THESE THE MOMENTS, SHEARS AND THRUST REQUIRED IN THE DESIGN OF COMPLICATED CONTINUOUS FRAMES. FOR CONVENIENCE OF REFERENCE, DEFINITIONS OF THREE TERMS ARE INTRODUCED. THESE TERMS ARE FIXED-END MOMENT, STIFFNESS AND CARRY-OVER FACTOR. /ASCE/
