Abstract Glass fibers reinforced polymer (GFRP) were used to longitudinally and transversally 12 columns while the other 4 with steel or GFRP as reference specimens. This research dealt several parameters under different loading conditions, such reinforcing material spacing between ties. study aims find out ability of bear loads. In addition, investigate mode failure in these their appropriaten...

Composite RCS building frames integrate reinforced concrete columns with structural steel beams to provide an efficient solution for the design and construction of earthquake-resisting structures. In this paper, an optimization framework is developed for performance-based seismic design of planar RCS moment resisting frames. The objective functions are defined as minimizing the construction cos...

The chloride corrosion of reinforcing steel in reinforced concrete (RC) structures is a significant reason for premature deterioration and failure of RC structures in aggressive environments such as Persian Gulf region. This is one of the most important sources of engineering and economic problems in developed countries. So, the repair and maintenance of RC structures exposed to corrosive envir...

Structural robustness is a significant property towards improving resilience of buildings, i.e. enhance their ability to withstand and recover from extreme events which often can cause local damage progressive collapse. It widely accepted that depends on the capacity structure activate alternative load paths (ALPs) after failure load-bearing elements, e.g. columns. Early evidence during World W...

Abstract One of the primary causes that can reduce lifespan concrete structures is chloride-induced corrosion reinforcing steel. Recent research has shown material properties, exposure conditions and climatic have a significant influence on structural deterioration reinforced (RC) structures, especially in marine environments. The objective this paper to predict durability RC damaged by near-sh...
