QUANTIFICATION OF THE SEISMIC BEHAVIOR OF A STEEL TRANSMISSION TOWER SUBJECTED TO SINGLE AND REPEATED SEISMIC EXCITATIONS USING VULNERABILITY FUNCTION AND COLLAPSE MARGIN RATIO

Transmission towers are a vital lifeline for modern living and are crucial structures that must remain operational even after a seismic event.However, the towers are largely designed to withstand the effects of wind alone and not earthquakes, and the seismic influences on tower design here and construction have hitherto been ignored.The purpose of

The compressor global geometric model including the endwall and the blade is parameterized based on a directly manipulated free-form deformation (DFFD) approach.A meridional flow streamline curvature method for solving inverse and forward problems is applied to the reverse design and performance analysis of the compressor.Combined with an improved

Background and objectives: Astragalus is one of the most abundant genera of flowering plants coq-clear 100 ubiquinol in Iran.There are a few reports on phytochemical investigation of this valuable genus.Saponins, flavonoids and polysaccharides have been reported as the most important metabolites in Astragalus species.In the present research, we aim

Abstract Humans and many other animal species act in ways that benefit others.Such prosocial behaviour has been studied extensively across a range of disciplines over the last decades, but findings to date have led to conflicting conclusions about prosociality across and even within species.Here, we present a conceptual framework to study the proxi
