Vulnerability assessment of RC structures by adopting an approach covering constructional and environmental impacts and presenting rehabilitation solutions-a case study of Abadan Panje Mehr Stadium

Abstract

The catastrophic consequences of recent earthquakes and the studies concerning the resultant damage to structures has indicate that some reinforced concrete structures may have poor performance once shaken by earthquakes despite their substantial resistance to gravity loads. Environmental factors may also prove detrimental through the lifespan of the structures. Therefore, the necessity for the strengthening and rehabilitation of the structures with reliable, convenient, and quick methods arises, especially with regard to resistance to lateral loads. Since most vulnerable structures have already been built, enhancing their seismic resistance would result in some constructional problems and architectural changes. The present study investigates various types of environmental and constructional damage suffered by RC structures and the respective rehabilitation methods. In this study, the effects of environmental and construction conditions on Abadan Panje Mehr Stadium are examined. No doubt poor construction quality, bad choice of material, and the water and soil in the vicinity of the structure have contributed to the development of many cracks, resulting in the failure of the structural elements. In this study, the damage to the building has been examined, the effects of each of the above-mentioned factors are analyzed, and eventually, some practical solutions for its rehabilitation are proposed.
