Engineered cementitious composite (ECC) is a high-performance material with greater shear deformation and strength than normal concrete, which has been proposed for use as component in structures. This study modeled three frames, pure reinforced concrete (RC) frame, an RC frame short columns ECC columns, using the incremental dynamic analysis (IDA) method to evaluate contribution of structural ...

Received: November 11, 2016 Revised: January 26, 2017 Accepted: February 10, 2017 Abstract: Introduction: Square reinforced concrete (RC) columns with the confinement effect of transverse reinforcement perform well in ductility and have been used widely in RC structures. Its behavior is the classic topic of anti-seismic and anti-collapse analysis of RC structures. With the advancement of the fi...

This paper aims to assess the structural overstrength (R), seismic behaviour factor (Q), and effective inertia (keff), of which elastic stiffness (Keff) is a function, i.e., Keff reinforced concrete (RC) cantilever columns with solid circular sections in urban bridges. The R Q factors proposed design codes have been based mainly on an empirical basis. However, some studies suggest that, case RC...

Accurate constitutive models of the constituent materials in a reinforced concrete (RC) section, namely, unconfined concrete, confined concrete and reinforcing steel are necessary in fiber-based discretization of RC components for use in nonlinear analysis of RC structures. This paper examines the sensitivity to different constitutive models in predicting the inelastic seismic behavior of RC fr...

A steel damper column is an energy-dissipating member that suitable for reinforced concrete (RC) buildings and multistory housing. To assess the seismic performance of with columns, peak displacement whole building energy dissipation demand dampers must be evaluated. This article proposes energy-based prediction procedure cumulative response RC frame columns. The proposed considers two energy-r...

Freeze–thaw damage is one of the primary causes deteriorating seismic resistance reinforced concrete (RC) structures. This paper proposed a freeze–thaw deterioration model for C30 concrete, and it can be employed to study time-varying performance aging RC columns. Next, this developed fragility analysis framework columns considering effect damage. Considering geometric parameters case-study bri...

Experimental studies were conducted by some researchers to investigate the cyclic performance of CFSretrofitted columns; however there is a need to develop analytical methods which can simulate its hysteretic response. This study presents an analysis of the hysteretic behavior of CFS-retrofitted reinforced concrete circular columns. Fiber element analysis was conducted based on cyclic constitut...

This paper investigates the effect of cross-section aspect ratio and load eccentricity on behavior RC short columns with large-scale specimens wrapped external carbon fibe...
