safety is one of the life necessities and fundamental human rights and it is a prerequisite for improvement of people welfare and health. safety improvement is in a direct relationship with mental calmness and also with senses of places to life environment. although the importance of safety factors for everybody, researches show that sensitivity or safety level for some kinds of age and sex gro...

Although several studies have investigated the effect of degradation on the behavior of structures, investigations on collapse margin ratios are rare in the literature. In this study, the effect of strength and stiffness degradation on collapse capacity of steel moment frames is investigated. The aim is to determine margin of safety against collapse using a probabilistic approach. For this reas...
