threaded through ducts in the segments and the cables tensioned. The trusses would then be hydrau- lically winched forward over the completed span into position over the next pier ready for the con- struction of another span.
Electronic computers had to be used by the designers to carry out plane frame analyses to determine preliminary member sizes and for the highly indeterminate space frame structure analyses covering factors such as joint rigidity, torsional stiffness and truss curvature.
The CSIRO's tests with the model illustrated the feasibility of the plan and the method of ten- sioning a complete span at a time will mean rapid progress. Speed of construction is important be- cause the project is financed by an interest-bearing loan and it will become revenue-earning from toll fees on completion.
Slender pyramid for San Francisco
A dramatic white pyramidal office building, 55 storeys high and topped by a 240 ft. spire reaching
Transamerica Building
a point 1,000 ft. above street level, is to be erected in San Francisco.
It will be 130 ft. square at ground level, tapering to 50 ft. square at 55th level. Car parking space will be underground and the build- ing will be served by 15 high- speed lifts. Total floor space will be 475,000 sq. ft.
Estimated to cost US$30 million, the building is owned by Transamerica Corporation and is designed by William L. Pereira & As- sociates. The structural en- gineers are Chin and Hensolt. Construction will begin in December 1969 and the building will be ready for occupation in Spring, 1971.
According to the archi- tects, the pyramid design is ideal for dense urban areas as it admits a maximum of light and air to the street below.
Swedish-Hungarian building venture
A private Swedish construction firm operating internationally, AB Bygging, Stockholm, and the Hungarian State building enterprise EM 31, with a staff of some 5,000 are to form a joint company for the international exploitation of inventions in the construction field.
The joint venture follows several years of co- operation in experimental construction of high-rise conical concrete structures according to the slip- form method, such as water towers and cooling towers.
You see Stanley in all the best places.
The choice of discriminating architects. Stanley hinges should be considered for every architectural project if ele- gance, engineering and function are important. The hand- some BB600 hinge shown above is seen in all the best places, whether they be public institutions and hospitals, or hotels and apartments. Contract hinges are our best effort. Why not put them in yours?
