Title: Algorithm for Calculation of Carry-over Factors, Stiffness Factors, and Fixed-End Moments for Beams with Variable Cross Sections
Author(s): John E. Sadler
Publication: Journal Proceedings
Appears on pages(s): 272-275

Abstract:An algorithm or computer method is resented for determining carry-over factors, abso ute stiffnesses, and fixed-end moments for concrete members with variable cross sections. Input for the algorithm consists of the moment of inertia, length, uniform loading, and concentrated loading for each segment along the member. The output can be used in standard moment distribution methods or slope deflection methods of analysis of elastic frames, as well as input to matrix analysis programs.
