Concrete: Specifying Water Content : (K. McSweeney)
Occasionally in the Concrete Section of many project specifications, the technical description defining the concrete often includes requirements that affects the water content. This may be expressed in terms that place limits on properties such as water cement ratio, maximum slump on site, total free water content etc. In some circumstances this can effect the placing and workability properties of concrete which in turn may have a bearing on the durability of a project.
Concrete: GRC Permanent Formwork : (D.K. Bull)
There are many approaches to effecting the support and/or containment of fresh concrete during casting operations. Costs associated with the provision of formwork can represent a significant proportion of the total cost of reinforced concrete construction. Permanent formwork systems tend to offer a quite different "mix" of costs from those which characterise the more traditional approach. The use of alkali resistant fibre glass.
Structural Steel: Value Engineering and Steel Economy : (G.C. Clifton)
In February 1992 edition of the American Institution of Steel Construction?s Journal, an excellent paper was published offering 35 tips on reducing fabrication costs during the design stage. In this paper Charles Clifton has taken most of the tips and suggestions raised and presented them in a form directly suited to New Zealand conditions.
Liability for Latent Structural Defects : (Tony Paterson)
Engineers may well be in breach of the contract with their client if a building suffers from structural defects or, in terms of the new Building Act, fails to perform as required. However, liability to subsequent Owners of the building who discover previously hidden latent defects is less certain.
NZ Building Code ? An Introduction to the Fire Safety Approved Documents : (Colleen Wade)
With the introduction of the New Zealand Building Code regulations dealing with fire safety design of buildings are about to change. This article is intended to highlight some of the key features regarding the new system that designers need to understand.
COMPUTER CORNER
General Cross Section Analysis : (P.J. Thompson)
A computation method for the flexural analysis of concrete and concrete masonry members is presented. The method which is suited to micro-computers, has a very wide scope of applications. The method is flexible and can cope with many different grades of concrete, any polygon shape, and a number of different bar sizes and grades of steel, prestressing and partial prestressing, drying shrinkage and thermal changes, Composite and staged construction.
