Research Reports and Memoranda

Starting from the integral equation for the inclination of the compression‐bending axis, simple approximate formulæ are derived for the deflection of bars with variable rigidity and variable axial loading under compression‐bending loads. By means of selected examples it is shown that the approximate formulæ developed are adequate for the treatment of any case likely to occur in practice. Simple processes are given for the calculation of the first and second order buckling loads appearing in the approximate formulæ. The method is applied integrally in a standard example, comparison with other methods being included.
