Abstract: A 3D indeterminate strut-and-tie model is developed for the analysis of a footing system to explain the cause of cracking and to develop a rehabilitation solution. The performance predicted with the model, simulating the ...

Abstract: An analytical model that incorporates time-dependent effects (creep and shrinkage) was developed to predict the long-term deflection of cracked reinforced concrete beams under sustained loading. The deflection model includes ...

Abstract: Testing results of six existing prestressed concrete bridges are used to evaluate analytical methodologies. These bridges cover different span lengths, number of lanes, and skew angles. Strains, load distribution factors, ...

Abstract: The paper discusses a few issues related to capacity rating of existing bridges using field test results. The principles of proof and diagnostic load tests for capacity evaluation are presented through discussing the rating ...

Abstract: Precast AASHTO concrete bridge I-beams are often supported at the ends by elastomeric bearing pads. The bearing pad-bridge beam interface defines support boundary conditions that may affect the performance of the bridge. ...

Abstract: The analysis and design of composite girders of cable-stayed bridges are discussed. Cable-stayed bridge girders carrying both axial forces and bending moments are actually beam-columns. The distribution of axial forces ...

Abstract: The practical applications of the finite-element software developed in Part I of this paper are demonstrated by analyzing the aerodynamic response of two prototype bridges, the Luling Bridge with a streamlined section, and ...

Abstract: A finite-element formulation is developed for analyzing flutter instability and buffeting response of long-span bridges and their interaction. The flutter derivatives, instead of the indicial functions used by previous ...

Abstract: In the process of manufacturing manhole inlets, strengthening rebars are placed at each side around the holes that are precast through formwork. Manufacturers have found it more economical by first casting the inlets and ...
