STRUCTURAL CONCRETE RESEARCH AND DEVELOPMENT IN NEW ZEALAND
Research and development has led to significant advances in the design procedures for seismic resistance. Precast concrete has been used recently to ensure good structural concepts and details. Cast in place reinforced concrete in connection regions provides the structural continuity and ductility needed to adequate seismic performance. A capacity design procedure has been developed to achieve ductile behaviour of structural systems responding to severe earthquakes. Research has been carried out into the properties of steel and concrete under seismic type loading, comprising shaking table tests on models and pseudo-static reversed load tests on subassemblages. Experimental work has been augmented by analytical and theoretical studies. The performance of reinforced columns subjected to severe seismic loading has been extensively studied and it has been realised that the joint core is a critical region in a moment resisting frame during severe seismic loading. The author outlines some areas of possible future research which include aspects of precast concrete construction, the use of high strength concrete and strengthening procedures for older structures.
