in this paper the rehabilitation of concrete structures with a new system is considered. in this system pre- stressed cables with energy dissipating viscous spring dampers at the end of each cable, are used to increase structure lateral stiffness. cable system can be replaced with other system due to their high tensile resistance, their easy replacement, high speed performance, economical matte...

This paper focuses on the exposure and fragility/vulnerability of residential, mixed residential/commercial, public building stock city Isfahan, in Central Iran, constitutes first part a seismic risk assessment study for that city. To determine assets at risk, we summarize details population from available georeferenced 2011 Census data. From this dataset local survey city, categorize taxonomy ...

Progressive collapse assessment of a reinforced concrete (RC) building designed only for gravity loads and lacking dedicated lateral load resisting system was carried out using the alternate path (ALP) method finite element (FEM) numerical model created in software SAP2000. Plastic hinge capacity members evaluated considering flexure (M), axial force (N) shear (V) interaction validated procedur...

Over the last few decades, there has been growing interest in use of low-carbon materials to reduce environmental impacts construction industry. The advent mass timber panels (MTP), such as cross laminated (CLT), allowed structural engineers specify a material for variety floor design considerations. However, serviceability issues vibration and deflection are limiting longer span timber-only sy...
