THE EXPERIMENTAL STUDY ON SEISMIC RETROFITTING EFFECTS OF REINFORCED CONCRETE PIER RETROFITTED BY DIAGONAL REINFORCEMENTS

Time-dependent Seismic Fragility Curves on Optimal Retrofitting of Neutralized Reinforced Concrete Bridges

A Theoretical Study of the Behavior of Reinforced Concrete Columns Strengthened by Steel Plates and Transverse Reinforcements

Jacketing of reinforced concrete columns is a common and useful strengthening method. This method substantially improves mechanical properties of the column, such as flexural strength as well as shear and ductility. In this paper, the behavior of confined reinforced concrete columns are investigated. The results indicate that the method is more effective for slender columns in the region of the...

Experimental Study on Seismic Performance of Reinforced Concrete Frame Columns Supported with Post-build Wing Walls

Abstract: Six specimens of concrete frame columns reinforced by post-build wing walls on the opposite faces were designed and fabricated to investigate their seismic performance. Axial compression ratio was considered as the critical factor and divided into 0.31, 0.36, and 0.40 before reinforcement. HRB400 steel grade was used to the longitudinal bar and the ratio of longitudinal reinforcement ...

a study on insurer solvency by panel data model: the case of iranian insurance market

the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.
