Cascini, F. Portioli, R. Landolfo  \nUniversity of Naples “Federico II”, Naples, Italy  \nABSTRACT: Durability design of new and existing structures is a key issue for the sustainable development of built-up environment. While the design procedure for reinforced concrete constructions was deeply investigated, the durability evaluation of metal structures has still to be fully analyzed and codified. The aim of this paper is to provide a first proposal for a general approach to the durability design of metal structures based on lifetime safety factor method. All the phases relevant to the design procedure have been discussed and defined in detail, according to a performance based approach. In particular, among the environmental deteriorating mechanisms which affect the durability of metal constructions, the atmospheric corrosion was considered. On the basis of the selected probabilistic corrosion models, which take into account different metal materials, corrosiveness of environment and effectiveness of coatings, the procedure for evaluating the design life corresponding to different environmental loads and limit states has been defined.  \n1 INTRODUCTION  \nSustainable Development (SD) was defined for the first time in the last 80s in the Brundtland Report (WCED 1987) as the “development that meets the needs of the present without compromising the ability of future generations to meet their own needs”. In the beginnings the strategic objectives just focused on environmental protection, while nowadays the field of interest has greatly enlarged, including also economic and social concerns.  \nAmong different human activities, which interact with the three SD dimensions, the construction sector plays an important role in delivering sustainable development requirements. Review of literature shows that the definition of a sustainable construction implies several statements, such as the efficient use of raw materials, the minimum use of energy and emissions during service life, the life duration and robustness, and a prolonged service life as target (CIB 1999) .  \nMetal constructions can easily satisfy the above mentioned requirements thanks to different features. They are recyclable and have high structural efficiency, design and manufacturing flexibility and speed of building. Such advantages provide lower raw material consumption, facilitate changing requirements avoiding obsolescence, and reduce the construction activities impact on the local environment by reducing emissions and noises.  \nDespite all the previous advantages, metal structures present some drawbacks, which are mainly related to durability, whose evaluation is necessary for a suitable maintenance and rehabilitation planning during life span.  \nAmong several factors that affect the life duration of metal structures, the atmospheric corrosion is recognized to be one of the major risk which decreases the performance of constructions, resulting in huge economic and societal losses.  \nIn terms of structural effects, the atmospheric corrosion causes the thickness loss of the cross section that leads to a smaller resistant area. The loading capacity of the element itself is reduced and the safety margin rapidly decreases.  \nBesides the effects on coatings, which could modify the exterior appearance of constructions reducing their aesthetic and economic value, corrosion represents an additional critical load which is able to lead the structures to collapse, specially when it is associated with high stress rates and cyclic loads, such as in the cases of stress and fatigue corrosion (Figure 1) .  \nFigure 1. Collapse of the Silver Bridge on the Ohio River due to stress and fatigue corrosion (USA, 1967) .  \nWith regard to life duration, even if international standards and codes provide general recommendations for preventing early ageing of constructions, the durability design of metal structures has s","cbCairxFZkS5Zo8K","https://ap.wps.com/l/cbCairxFZkS5Zo8K","pdf",241665,"English","# Introduction\n# Durability criteria in standards and codes","[{\"question\":\"What problem does the paper address in metal-structure durability design?\",\"answer\":\"It addresses the lack of a fully analyzed and codified procedure for durability evaluation of metal structures, despite advances for reinforced concrete.\"},{\"question\":\"Which degradation mechanism is specifically considered?\",\"answer\":\"Atmospheric corrosion is singled out as a major risk affecting metal constructions, including its structural and service-life impacts.\"},{\"question\":\"How does the proposed method evaluate design life?\",\"answer\":\"Using probabilistic corrosion models that account for different metal materials, environmental corrosiveness, and coating effectiveness, it defines design life for different environmental loads and limit states.\"}]","Durability design of metal structures based on lifetime safety factor method | PDF",1792792746]
