Such movements are caused by several influences on the structures, such as traffic loading, wind loading, temperature variations, as well as damage and corrosion."}, {"text_idx": "#000012", "text": "Arbei\u00f0s\u00f8kirMatrikulLand- og sjo\u0301kortLandsfo\u0301lkayvirlit og navnama\u0301lTingly\u0301singElveitingareftirlitArbei\u00f0s\u00f8kirOrkaSko\u0301gr\u00f8ktNa\u0301ttu\u0301ruverndUmhv\u00f8rvisverndNor\u00f0urlendskt samstarvSnarvegirGo\u0301\u00f0kenningar og loyvirKunnger\u00f0artalvaStarvsfo\u0301lkOy\u00f0ubl\u00f8\u00f0Umhv\u00f8rvisstovanUm Umhv\u00f8rvisstovunaStarvsfo\u0301lkSambandPrivatli\u0301vspolitikkur"}]
