' The computer program described by the author greatly simplifies the analysis of reinforced concrete columns subject to bi-axial bending. It has been used in my office
for some time and the data preparation is very much easier than the laborious hand calculation involved in Saville's method. '
A method is presented in which the differences in stay tensions necessary to maintain equilibrium in a mast subjected to wind loading are related to the actual tensions developed in the stays as a result of changes in length of the stay chords caused by a
displacement of the mast from an initial position.
As most of the piers of viaducts act as cantilevers for horizontal loads at top, requiring greater rigidity at base along longitudinal direction, a new type of structural element is suggested which is expected to serve as pier with reasonable efficiency. Rigidity at bottom is not much needed if piers act as a whole, being framed by top capping beam.
