A. STRUCTURES (1) Plastic Behaviour of Triangulated Trusses
Workers: L. K. Stevens, P. Grundy and D. Mansell
This work continued from the previous year. A series of triangu- lated trusses having members of rolled sections were tested by con- trolling straining.
Theoretical investigations into the prediction of behaviour using C.S.I.R.A.C. were undertaken.
A theoretical study of the behaviour of statically indeterminate systems in which the mode of collapse was controlled by varying the section of critical members was begun. A paper has been accepted for publication.
(2) Stress Distributions in a Concrete Shell Structure Worker: L. K. Stevens
This work, which was continued from the previous year, consisted of the following:
(i) Completion of experimental investigation of edge effects in a model dome with large arched cut-outs.
(ii) Measurement of strains and deformations in a full-scale re- inforced concrete shell structure when forms were removed.
The project is concluded and a paper has been accepted for publication.

(3) Scale Effects in Concrete Structures Workers: S. Aroni and L. K. Stevens
No significant progress has been made in this field owing to the absence of one worker from the University in the long vacation.
(4) Torsional Stiffness of a Latticed Girder Workers: H. Nolle and F. Laszlo
Work was continued from 1957 and is complete, although further refinement of the theoretical treatment will be attempted. A paper is to be prepared for publication.
B. ELASTICITY (5) Elastic Properties of Ferrite and Cementite
Workers: H. Nolle and F. Laszlo
Work was continued from 1957 and the present stage of the project is complete. A paper has been accepted for publication.
C. HYDRAULICS
(6) A Scale Model Investigation of Waves and Littoral D r i f t in the vicinity of Lome, Victoria
Workers: J. J. Fryer and J. D. Lawson
The project is continued from thc previous year. Following con- struction of the model basin, wave generator and measuring equip- ment, experimental work to investigate the wave and sand drift con- ditions for various breakwater shapes and locations is proceeding and nearing completion. A secondary problem of erosion of the surfing beach at Lome has been investigated during the year.
(7) Water Hammer in Simple Pipe Systems Workers: B. B. Sharp and I. C. O'Neill
Experimental work was carried out with temporary equipment as reported last year. The aim, to study rupture of water column, was fulfilled in one significant respect, demonstrating inadequacies in previous methods of analysis of conditions subjected to rupture. A method of analysis, confirmed by experimental results, has been formulated. A report is nearing completion. Research under the general title is to be continued.
(8) Air Entrainment in Closed Conduits Workers: B. B. Sharp and J. D. Lawson
The project involves a study of the mechanism of air entrainment in closed conduits. A transparent pipe 5 inches in diameter, arranged so it may be inclined at a variety of slopes between horizontal and vertical, has been installed.
Preparation of measuring equipment has commenced.

D. SOIL MECHANICS
(9) Stress Distribution in Two Layered Pavement Structures
Workers: D. H. Trollope and D. T. Currie (Country Roads Board Highway Research Fellow)
This project is continued from the previous year. Work has pro- ceeded to thc stage where a suitable pressure cell for single-cycle measurement has been developed. I t is desired, however, to achieve a satisfactory device for repeated cycle measurement and it has been shown that to date no suitable unit has been developed. A constant- temperature triaxial compression machine for testing bituminous mixtures has been designed and built in connection with this project.
Work is proceeding.
(10) Interaction of Structure and Foundations Workers: I. K. Lee and D. H. Trollope
This project was continued from the previous year. Theoretical solutions to describe clastic stress distributions arising from com- bined direct loads and moments applied to typical foundation units have been investigated. Development of direct reading pressure cells has been completed and extensive tests on the calibration behaviour of these cells have been carried out. Work is proceeding in an attempt to develop an ideal cohesive (0 = 0 ) material for model tests.
(11) Shear Strength of Soils
Workers: D. H. Trollope and J. R. Morgan (G.M.H. Research Fellow)
Work was continued from the previous year. The experimental programme aimed at evaluating the effect of colloidal structure on the shear strength of kaolin is in progress.
(12) Earth Pressure Measurements on a Culvert at Tullaroop Dam, Victoria (in collaboration with State Rivers and Water Supply Commission of Victoria)
Workers: D. H. Trollope and I. K. Lee
A pressure gauge and strain measuring system was installed in the outlet culvert at Tullaroop Dam with a view to investigating thc earth pressure imposed on thc culvert during construction of the dam. Construction is now nearly complete and continuous records are being made.
(13) Stability of Rockfill Dams
Workers: D. H . Trollope, J. D. Lawson and B. Sandie
Work was commenced on a project sponsored by the Water Re- search Foundation of Australia L t d . The aim of this investigation is to evaluate the capacity and stability of rockfill dams in which

flood flow is discharged through the dam. Work to date has con- centrated on the design and construction of a large flume to accom- modate the proposed model tests.
E. AGRICULTURAL ENGINEERING (14) Tractor Testing
Workers: G. H. Vasey and W. F. Baillic
The formal testing of tractors and of stockmodel and prototype spark arresters, and of small engines. Testing of spark arresters has led to significant redesigns and improvements in performance.
(15) Farm Water Supplies—A Field Survey in Northern Victoria Worker: R. J. de Laine
This work, referred to in previous years, has now reached the reporting stage. A survey of the water facilities (stock, domestic and irrigation) on 149 farms in Northern Victoria reveals a low standard of objective and attainment—a long way below the potentials of stock carrying capacity i f these were to be improved and reasonably well exploited.
(16) A Study of Engine Exhausts Worker: D. H. C. Beach
A n attempt is made to study the following features of the exhausts of typical diesel (tractor) engines: temperatures, the emission of 'sparks', back pressure. Carbon deposits have been collected and examined from the piston crowns and cylinder heads, and from exhaust manifolds, tubing, mufflers and spark arresters of a number of engines in field use.
In an attempt to measure the temperature of sparks emitted from exhaust stacks, an optical-photographic system has been devised whereby the photographic image of the spark can be compared with the image of a calibrated optical wedge.
(17) Wheat Harvester Studies Worker: W. T. Brown
In the harvest season of 1958-59, the performance of some 30 wheat harvesters was studied in the field, a day at a time. The survey noted such features as grain losses, other losses of production and, at the same time, the weather data for the day and the moisture in the grain and plant material. Size distributions of the collected samples are also being studied.
(18) Irrigation Studies Worker: D. Farrell
A study of the hydraulics of the application of water to the soil
C I V I L E N G I N E E R I N G 101
has begun, with a view to studying the hydraulic features that lead to uniform infiltration. Bay irrigation will be studied first.
