Abstract: An analytical procedure was developed to predict the compression membrane behavior of laterally restrained reinforced concrete members subject to extreme loads, such as those generated by the loss of bearing elements or ...

Abstract: A combined experimental and analytical investigation was conducted at the University of Ottawa to assess the performance of blast-resistant window retention anchors to generate design information. The experimental phase ...

Abstract: A hysteretic model is proposed for shear response of reinforced concrete members subjected to shear force and bending moment reversals. The model consists of a primary shear force‐shear displacement curve and unloading and ...

Abstract: The use of high-strength concrete (HSC) in seismically active regions poses a major concern because of the brittle nature of the material. The confinement requirements for HSC columns may be prohibitively stringent since ...

Abstract: Lateral prestressing of concrete columns was investigated as a method of seismic retrofit. Experimental research was conducted to develop a design procedure for shear deficient concrete columns. The technology consists of ...

Abstract: The use of high-strength concrete (HSC) in seismically active regions poses a major concern because of the brittle nature of material. The confinement requirements for HSC columns may be prohibitively stringent when ordinary ...

Abstract: Strengthening of concrete structures using fiber-reinforced polymer (FRP) systems has become a widely accepted technology in the construction industry over the past decade. Externally bonded FRP sheets are proven to be a ...

Abstract: A mathematical model is developed to express the stress-strain relationship of high-strength concrete confined by transverse reinforcement. The model is applicable to both normal-strength and high-strength concretes, ...

Abstract: Behavior of high-strength concrete columns with concrete strengths of up to 90 MPa was investigated experimentally. Large-scale columns were tested under different levels of constant axial compression and incrementally ...

Abstract: An analytical model is proposed to construct a stress‐strain relationship for confined concrete. The model consists of a parabolic ascending branch, followed by a linear descending segment. It is based on calculation of ...
