A damage-based approach for the performance-based seismic assessment of reinforced concrete frame structures is proposed. A new methodology for structural damage assessment is developed that utilizes response information at the material level in each section fiber. The concept of the damage evolution is analyzed at the section level and the computed damage is calibrated with observed experiment...

recent debates concerning sustainable agriculture have received many attentions, but efforts concerning materialization of the concept haven’t enough. if the concept of sustainability is to be used as an underlying component of human interventions in the environment and ecosystem, a sound measure of sustainability is surely required. development of agricultural sector without considering the co...

During their service life, marine pipelines continually accumulate damage as a result of the action of various environmental forces. Clearly, the development of robust techniques for early damage detection is very important to avoid the possible occurrence of a disastrous structural failure. Most of vibration-based damage detection methods require the modal properties that are obtained from mea...

BACKGROUND The use of creatine (Cr) as a nutritional supplement to aid athletic performance has gained widespread popularity among athletes. However, concerns have recently been expressed over potentially harmful effects of short and long term Cr supplementation on health. METHODS Forty eight young healthy subjects were randomly allocated to three experimental protocols aimed at elucidating a...
