Abstract: Reinforcing old bridges with corrugated steel (CS) is gaining interest due to outstanding reinforcement effects and relative ease of implementation. The approach consists of positioning the CS member under an old bridge ...

Abstract: The paper proposes an improved method of analysis of reinforced concrete columns in braced (no-sway) frames, which is suitable as a simple computer solution for design practice and is more realistic than the existing ACI ...

Abstract: Periodic interior buckling of regular multistory and multibay rectangular elastic frames with elastic bracing is analyzed. It is shown that there exists a certain critical bracing stiffness for which the critical loads for ...

Abstract: A simplified fracture-mechanics-based model of compression failure of centrically or eccentrically loaded quasi-brittle columns is presented and the size effect on the nominal strength of a column is predicted. Failure is ...

Abstract: Edge-notched eccentrically compressed fracture specimens made of aggregate of reduced size are loaded in standard creep test frames. Measurements of the time rate of crack mouth opening in notched concrete specimens subjected ...

Abstract: Recycled aggregate concrete–filled steel tube (RACFSTs) are attracting increasing attention from academics as a solution to use recycled aggregate concrete (RAC) as main load bearing members in multilevel or even high-rise ...

Abstract: Concrete-filled steel tubular (CFST) arch bridges have gained popularity over the last decades for use in long-span applications. At service conditions, these bridges are influenced significantly by the time-dependent ...

Abstract: Concrete-filled steel tubular (CFST) arch bridges have the advantages of high compressive strength, light self-weight, and convenience in construction, and thus have been widely used in recent years. The current codes or ...

Abstract: The paper presents an improvement of the microplane model for concrete—a constitutive model in which the nonlinear triaxial behavior is characterized by relations between the stress and strain components on a microplane ...
