A numerical procedure for the analysis of plane frames of an elastic, perfectly plastic material is presented. The problem is a quadratic programming problem and an algorithm for the solution is given which permits the analysis of frames in the elastic-plastic range. The analysis can be applied to either steel or reinforced concrete frames within the range of acceptable hinge rotations.
The paper descriptionbed a numeric method for calculating the interception capacity of lateral kerb inlets of prescribed lengths. It discussed the proposition that on moderate to steep road gradients capacity can be substantially improved by incorporating an extended length of depressed gutter up-stream of the inlet. Design charts for road crossfalls of between two per cent and six per cent were included.
