Abstract: In this paper, serviceability limit states of prestressed concrete bridges are examined. Allowable compressive and tensile stresses in concrete under service loads are first used to determine the upper and lower limits of ...

Abstract: A generalized constitutive model based on hypoelastic theory is proposed to characterize the stress-strain relationship of plain concrete under monotonic and cyclic nonproportional loading. First, the existing hypoelastic ...

Abstract: This paper presents the results of an experimental program undertaken for evaluating the effectiveness of ultrahigh performance fiber-reinforced concrete (UHPFRC) for strengthening deficient tension lap splices. A total ...

Abstract: This two-part paper is an application of advanced nonlinear finite-element analyses (ANFEA) for the design or assessment of large concrete structures. It presents an innovative application of ANFEA that reveals many important ...

Abstract: This second-part article presents applications of advanced nonlinear finite-element analysis for the design of large reinforced-concrete structures. Because shear and the size effect are fundamental aspects of these ...

Abstract: This paper proposes a methodology that uses advanced nonlinear finite-element analysis for determining a global resistance factor for the design of reinforced concrete structures. It introduces a new reliability approach ...

Abstract: Development in ultra-high-performance fiber-reinforced concrete (UHPFRC) structural applications that has taken place over the last two decades has generated innovative concepts that could significantly impact the concrete ...

Abstract: In this paper, the use of localized tendons to prestress statically indeterminate structures is examined. To determine the prestressing moments produced by localized tendons, the fixed-end moments should first be computed. ...

Abstract: A comprehensive study has been conducted to investigate the long-term behavior and strength of partially encased composite columns made with thin-walled welded I sections stiffened with transverse links. The paper presents ...
