RISFull-Range Shear Behavior of a Nonprismatic Beam with Steel Trapezoidal Corrugated Webs: Experimental Tests and FE Modeling
Publisher: ASCE
Abstract: This paper presents the first experimental and numerical investigation of the full-range shear behavior of a nonprismatic overhanging beam with concrete slabs and steel trapezoidal corrugated webs. The results showed that ...
Effect of Multiple Environmental Factors on the Adhesion and Diffusion Behaviors of Chlorides in a Bridge with Coastal Exposure: Long-Term Experimental Study
Publisher: ASCE
Abstract: Corrosion of steel reinforcement caused by airborne salt penetration into concrete cover is a very important reason for the deterioration of concrete structures exposed to an atmospheric marine environment. The current ...
Shear Performance of Tapered Beams with Concrete Flanges and Corrugated Steel Webs: Theory, Experiments, and Numerical Simulations
Publisher: ASCE
Abstract: This study experimentally and numerically demonstrated that the traditional basic shear method is not applicable for estimating the shear stresses in tapered beams with corrugated steel webs (CSWs). The vertical components ...
Deformation of a Tapered Box Girder with Trapezoidal Corrugated Steel Webs Considering the Resal Effect: Theory, Experiments, and Numerical Simulations
Publisher: ASCE
Abstract: Due to the weakened shear stiffness of trapezoidal corrugated steel webs (TCSWs), it is necessary to account for shear deformation in calculating the total deformation for girders with TCSWs. Most of the existing research ...
Shear Properties of Tapered Box Girders with Steel Trapezoidally Corrugated Webs Considering Resal Effect
Publisher: ASCE
Abstract: A study on the shear properties of tapered box girders with steel trapezoidally corrugated webs (STCWs) considering the Resal effect was carried out based on theoretical analysis, experimental testing, and numerical ...
New Asynchronous-Pouring Rapid-Construction Method for Long-Span Prestressed Concrete Box Girder Bridges with Corrugated Steel Webs
Publisher: ASCE
Abstract: Based on the traditional hanging basket cantilever construction of the prestressed concrete box girders, combined with the excellent shear capacity of the corrugated steel webs (CSWs), this paper introduces an improved ...
Shear Stress Calculation and Distribution in Variable Cross Sections of Box Girders with Corrugated Steel Webs
Publisher: American Society of Civil Engineers
Stress Analysis of Linear Elastic Nonprismatic Concrete-Encased Beams with Corrugated Steel Webs
Publisher: American Society of Civil Engineers
Abstract: The basic mechanical behavior of a nonprismatic concrete-encased beam with corrugated steel webs (CSWs) was investigated through a scale model experiment and finite-element model analysis. Because of the influence of ...
New Method for Generating Strut-and-Tie Models of Three-Dimensional Concrete Anchorage Zones and Box Girders
Publisher: American Society of Civil Engineers
Abstract: The determination of a suitable strut-and-tie model (STM) of a number of disturbed three-dimensional (3D) domains is a challenging task. To overcome this problem, this paper presents a performance-based ground structure ...
A Practical Approach for Generating the Strut-and-Tie Models of Anchorage Zones
Publisher: American Society of Civil Engineers
Abstract: This paper presents a practical method for automatically generating optimal strut-and-tie models (STMs) in anchorage zones. In the proposed approach, a new microtruss element pattern is created to build ground structures. ...
