pipeline that tips over the end of the stinger and undergoes a reversal in curvature before 

 coming back into contact with the stinger, are considered. A computer-oriented numerical 

 solution is used to solve the problem for various values of the governing parameters, and the 

 effect of these parameters on the pipeline bending stresses is discussed briefly.

Paper discusses an analytical study of the effect of axial tension on the moment 

 carrying capacity of pipelines. The study was made for the case where the pipeline is 

 stressed beyond the elastic limit, with the effect of ^ipe ovahng taken into consideration. 

 An analysis by Ades, which uses the principle of least work to determine the effect of 

 ovaling on a cylindrical tube under pure bending when part of this tube is beyond the elastic 

 limit, was extended to include the effect of axial tension. The procedure of the analysis and 

 the results of the study are given.

Proceedings paper describes experimental tests made with thin-waUed steel tubing to 

 verify and compare an analytical tlieory procedure of predicting the relationship between 

 bending moment and curvature in both the elastic and plastic ranges for tubes subjected to 

 bending plus axial tension. Graphs comparing the theoretical and experimental results are 

 given, along with a discussion of the results and their comparison.

Article briefly describes the design and construction of the intake structures for the 

 cooling water system of a nuclear powerplant at Wylfa Head in Anglesey, Great Britain. The 

 vertical shaft and undersea tunnel were constructed underwater by divers, using large precast 

 concrete blockwork. A tubular steel jetty and headwork structure were constructed by 

 overhand methods to provide both permanent and construction access to the site of the 

 intakes.
