Abstract: This paper provides background on the use of lightweight aggregate concrete in long-span bridges. Observed time-dependent deflection of long-span lightweight aggregate concrete box-girder bridges is highlighted. The paper ...

Abstract: An analytical model, based on the commonly used equivalent cantilever concept, is developed for assessing the local ductility demand of a yielding pile-shaft when subjected to lateral loading. For elastic response of the ...

Abstract: This paper provides background on the use of lightweight aggregate concrete in long-span bridges. Observed time-dependent deflection of long-span lightweight aggregate concrete box-girder bridges is highlighted. The paper ...

Abstract: In this paper, the requirements for the sectional depth of prestressed concrete beams satisfying the permissible stress limits are examined. An explicit expression for the member depth is derived in terms of three geometric ...

Abstract: This paper studies the feasibility of replacing damaged deck of posttensioned concrete box-girder bridges without the use of falsework to support the superstructure span. Parameters of the study included straight, curved, ...

Abstract: In multistory buildings, coupled shear walls are frequently used as the main lateral load resisting system, the seismic design of which requires some knowledge of their periods of vibration. Although the vibrational ...

Abstract: Results of an experimental program investigating the lateral strength and ductility capacity of reinforced concrete piles are presented. Four full-scale reinforced concrete piles with details representative of the current ...

Abstract: The derivation of funicular shapes for submerged arches has been the subject of a number of studies. In a recent paper, the solution governing the shape of the arch was derived in a coordinate system involving the arc length

Abstract: In the U.S. bridge design practice, an approach slab is commonly provided to facilitate a smooth transition from the highway pavement to the bridge deck. Maintenance of bridge approaches often necessitates the repair or ...
