Current seismic design philosophy used worldwide tolerates a degree of damage at locations predefined by the designer, as long as a complete structural collapse is precluded. By accepting plastic deformations, the maximum acceptable forces can be controlled and construction costs can be reduced. Major earthquakes, e.g. the Canterbury earthquakes, showed that well-designed structures behave as anticipated. The joints suffered plastic deformation as the designer intended, while the occupants remained alive. Repair costs, however, were often high. Costs also accrue because, post-earthquake, the infrastructure is no longer fit for purpose. These costs are very difficult to predict. Low-damage seismic design, in contrast, can be achieved by activating rigid-like body movement of structural members. Development of forces resulting from structural local deformation can then be prevented. Consequently, associated damage to structural members can be avoided. Recent research outcomes at the University of Auckland Centre for Earthquake Engineering Research will be presented.

In modern days for structures in coastal areas it has been observed that the premature structural failures are occurs due to corrosion of the reinforcements of the designed structural member. The corrosion causes the structural damage which in turn leads to reduction in the bearing capacity of the concerned structural members. The aim of this study was to study the effect of partial replacement of fly ash to minimize the corrosion effect. Beams were designed and corroded by using artificial method known accelerated corrosion method. The beams were then tested for flexural and bond strength. Also the weight loss of the reinforced bars was been determined using electrical resistivity method. The fly ash will replace by 10% and 15%.The strength will calculate at varying percentage of corrosion at 10% and 15%. Beams will cast at M25 grade concrete. The flexural strength will test by using UTM and the bond strength will calculate using pullout test.
