RISStressing Sequence for Hanger Replacement of Tied-Arch Bridges with Rigid Bars
Publisher: ASCE
Abstract: The construction of bridges with suspenders, such as cable-stayed or tied-arch bridges, needs deep study of the prestressing forces to be applied to stays or hangers in all stages, depending on the construction technique ...
Serviceability and Ultimate Safety Checks of Segmental Concrete Bridges through N-M and M-V Interaction Domains
Publisher: American Society of Civil Engineers
Abstract: In current engineering practice, safety checks on serviceability and determinations of ultimate limit states of segmental bridges built by cantilevering are generally performed, either considering separately the contributions ...
Vulnerability of a Damaged Bridge Abutment in a Seismic Area
Publisher: American Society of Civil Engineers
Abstract: The case of the abutment of a motorway urban viaduct damaged by human intervention is presented. Built in the 196s, it lies in a critical seismic area and the human-induced damage involved the elements of the abutment ...
Virtual Slope Control of a Forward Dynamic Bipedal Walker
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Active joint torques are the primary source of power and control in dynamic walking motion. However the amplitude, rate, timing and phasic behavior of the joint torques necessary to achieve a ...
The Viscoelastic Standard Nonlinear Solid Model: Predicting the Response of the Lumbar Intervertebral Disk to Low-Frequency Vibrations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Due to the mathematical complexity of current musculoskeletal spine models, there is a need for computationally efficient models of the intervertebral disk (IVD). The aim of this study is to ...
Simplified Procedure for Evaluating the Effects of Creep and Shrinkage on Prestressed Concrete Girder Bridges and the Application of European and North American Prediction Models
Publisher: American Society of Civil Engineers
Abstract: The effects of time-dependent phenomena on concrete prestressed girder bridges are investigated. The study concerns the case of bridges built directly in their final configuration and that of bridges built by a sequence ...
A Numerical Simulation Algorithm of the Inviscid Dynamics of Axisymmetric Swirling Flows in a Pipe
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Current simulations of swirling flows in pipes are limited to relatively low Reynolds number flows (Re < 6000); however, the characteristic Reynolds number is much higher (Re > 20,000) in most of engineering ...
Assessing Corrosion on Steel Structures Using Corrosion Coulometer
Publisher: American Society of Civil Engineers
Abstract: Corrosive exposure and subsequent deterioration of weathering steel structures cause strength loss due to cross-section thinning as well as crack susceptibility due to formation of notches that concentrate stresses. Key ...
Partial Elastic Scheme Method in Cantilever Construction of Concrete Arch Bridges
Publisher: American Society of Civil Engineers
Abstract: In this paper, a study about stay stressing procedures of concrete arch bridges built by cantilevering with temporary stays is presented. Particularly, the partial elastic scheme method is proposed to find the initial cable ...
