Technical Paper “McLean Park Grandstand”
T W Robertson and B Williams
Abstract
In 1984 the wooden Harris Stand at McLean Park Napier was destroyed by fire, and in August 1984 a new stand was given the go-ahead. Planning proceeded with a 5,500 seat stand. The planning provided for future development to link the stand with Centennial Stand to the South and the embankment to the North. Fiancial constraints limited construction to a little over 4,000 seats.

Technical Paper Tensile Membrane Structures
J T Dale, B T Davis, E Moodie
Abstract
Numerous membrane structures exist in nature adn this type of building envelope is becoming increasingly popular with designers and owners. The paper briefly views the history, structural principles, design and construction of tensile membrane structures with reference to NZ and Australia and especially to Sunhill Garden centre, Pakuranga, Auckland. This structure covers some 900m² and is supported by steel masts and precast concrete buttresses. It is the largest fabric tensile structure in NZ at the time of writing.

Computer Column Dynamic Analysis and Software for Seismic Analysis
Stuart Hodder, Don Campbell
Abstract
For typical structural engineering applications, perhaps 95% of design requirements are fulfilled with static analysis. In dynamic situations such as seismic or wind loading on structures approximate empirical techniques are used to convert the problem into a static formulation. However there are instances where a more precise treatment of the true vibrational characteristics may be required.

Technical paper Durability of Reinforced Concrete Materials and Workmanship Factors
Summarised from a paper presented at IPENZ Conference 1988
Abstract
Concrete as a material on its own has a reputation as a long lasting and durable material. In its role in reinforced concrete, it performs a dual role:
1. It is an integral part of the structural load carrying system with the reinforcing steel.
2. It provides a protection system to prevent the corrosion of the reinforcing steel.

Technical Paper Climate Change Implications for Design Wind Speeds
S J Reid
Abstract
The difference, from present conditions, of the surface pressure pattern in a greenhouse scenario for NZ at about the year 2050, has been inferred from current trends. It may lead to shifts in predominant wind direction. There does not appear to be a significant effect on basic wind speeds for design. The increased frequency of tropical cyclones which would be associated with an increase of surface temperature of 3⁰C in the NZ area appears to be important and would lead to tropical cyclones becoming the dominant cause of high winds, for design purposes, in Auckland and probably over much of the North Island.
