![]() NLTHA and performance based assessment methodology concluded a seismic assessment rating in the range 35-45%NBS which, whilst above an Earthquake Prone threshold, identified a number of critical structural weaknesses (CSW’s). An Initial Seismic Assessment (ISA) of the Majestic Centre was followed by Detailed Seismic Assessment (DSA, 2011) of the structure using both modal response spectrum (MRSA) and non-linear time-history (NLTHA) analysis methods. Following the Canterbury Earthquakes, the building’s owner, Kiwi Property, commissioned seismic assessments of their property portfolio. The tower has a dual lateral load resisting system a perimeter reinforced concrete moment frame and two central shear cores. Constructed circa 1991, the building comprises a 25 storey tower above a five storey podium. ![]() ![]() The Majestic Centre is located in central Wellington, New Zealand. The worskhop was organised under the auspices of RILEM EAC (Educational Activities Committee), with the aim to bring together young researchers in the field of durability of concrete.J. ASR, and acid, sulphate and frost attack and other mechanisms remain important areas of study. In addition, the interaction between different degradation mechanisms requires further understanding. Modelling of chloride penetration and carbonation has attracted a great deal of attention in recent years, however, there is still much debate on several essential aspects such as the chloride threshold level. Corrosion of steel reinforcement is considered to be the most detrimental process responsible for structural deterioration.Many studies are in progress to develop a comprehensive engineering approach for assessment of the initiation and the propagation period of corrosion in both uncracked and cracked concrete. Reinforced concrete structures may prove to be very durable, however, their gradual degradation over time impairing both serviceability and structural safety is still a matter of great practical concern in view of the large economic consequences for assessment, maintenance and repair. Topics discussed in the book are related to durability performance of reinforced concrete, service life modelling, prevention, protection and repair. ![]() This volume contains the proceedings of the 8th International PhD Student Workshop on Service Life and Durability of Reinforced Concrete Structures that was held in Marne-la-Vallée, France, on September the 26th and 27th 2016. ![]()
