Steel braced frames are commonly used in steel structures to control and improve the seismic performance of under severe lateral forces such as an earthquake. So, providing better formability would help designers achieve their desire level. This study is focused on utilizing curved dampers ductile frame instead using knee elements provide energy dissipation, strength, elastic stiffness during c...

This paper describes the seismic performance of a steel frame with additional LYP dampers. dampers provides passive energy dissipation device in structure, it also reduces lateral forces efficient way which is produced by wave. The structures needed design especially countries where activities occur. analysis accomplished FEM and software called SAP2000. only analyzed using numerical simulation...

Abstract The steel frame with portal plate shear wall unit presented here is a new structure by assembling the into through bolt connection. For study of resistance and bearing capacity structure, it necessary to conduct experimental research. Three specimens are made here, two geometric shapes case setting stiffeners not considered respectively. concentrated lateral load applied in test displa...

nowadays, by increasing the emphasis on the environmental protection by organizational stakeholders, including government, customers, employees, competitors and communities, environmental management is becoming more important for corporations. integrating environmental management techniques along the supply chain is an appropriate method for enhancing the environmental performance of an industr...
