TECHNICAL PAPERS
Appropriate Material Values for Use in Concrete Masonry Design - J.M. Ingham, P.T. Laursen, K.C. Voon.
The objective of the paper is to discuss appropriate material properties for grouted concrete masonry manufactured in New Zealand, with the hope that this exercise may prove useful when conducting a future re-write of NZS 4230, the NZ masonry design standard. The discussion first targets the concrete masonry crushing strength, the modulus of elasticity and strain capacity. Strength and strain enhancement of the wall compression zone due to confinement is also discussed, and a review of criteria from current research and international masonry design standards is included. The paper then compares results derived when using different equations to predict the maximum in-plane shear strength of reinforced fully-grouted masonry walls. These expressions are correlated with a comprehensive database of test results to establish their suitability. It is concluded that the NZ and Australian masonry design standards are conservative in predicting masonry shear strength, and a recommendation is made for the most suitable candidate for inclusion in a future harmonised Australia/New Zealand masonry design standard.
Use of the new Grade 500E Reinforcing Steel - Professor R. Park.
The use of the new high strength steel reinforcement Grade 500E is considered. The need for statistical information so that the overstrength factor for that steel required for aseismic design can be determined is pointed out. Some advantages and disadvantages of using high strength steel reinforcement in beams and columns of frames are discussed. A main application would be for transverse reinforcement to reduce the volume of confining reinforcement.
Recent Advances in Structural Steel Design Guidance for NZ, with an Emphasis on Durability - G.C.Clifton
This paper provides a brief and non-technical overview of the purpose behind and the scope of design guidance produced over the last ten years for structural steel use in buildings. A wide (but not exhaustive) range of design guidance is covered, with an emphasis on design for durability. References to more detailed sources of information are given, along with the contact details from which this additional information can be obtained.
Performance Grading of New Zealand Pine - Douglas Gaunt, John Roper, Bruce Davy
MGP (Machine Graded Pine) grading, what is it and the options for performance grading of our structural timbers are reviewed. Traditionally, MGP relies on MoEPmin (term defined in Section 3) as the grading parameter; this paper shows the effectiveness of this traditional grading parameter along with other grading parameters such as MoEPaverage (term defined in Section 3) and LmoEj (term defined in Section 3).
With any MSG method a known reliable relationship between grading parameter and the strength to stiffness of the graded timber is vital. This paper reviews the financial effects of the different grading methods and shows that the LmoEj (the E-graderTM parameter) results in better grade recoveries and hence higher financial returns.
