RISConcrete Strength of Vertical Joints in the Cantilever-cast Segment of Prestressed Concrete Box Girders
Publisher: American Society of Civil Engineers
Abstract: This study analyzed the influence of concrete compressive strength caused by vertical joints placed between cantilever-cast segments of various prestressed concrete (PC) box girder bridges. The vertical joints of two actual ...
Composite Unit-Based Evaluation of the Creep Effects of Continuous Prestressed Concrete Box Girders
Publisher: American Society of Civil Engineers
Abstract: To evaluate the influence of concrete creep effect on spatial stress in concrete, the formulas for recursive calculation of equivalent nodal loads of concrete creep of PC composite unit under multi-axial stress was considered. ...
Two Contrasting African Easterly Wave Behaviors
Publisher: American Meteorological Society
Abstract: AbstractThe dominant structural variability of African easterly waves (AEWs) is explored using an empirical orthogonal function (EOF) approach. The structure of AEWs is obtained by projecting the wind fields from reanalysis ...
Two Extratropical Pathways to Forcing Tropical Convective Disturbances
Publisher: American Meteorological Society
Abstract: Observational evidence of two extratropical pathways to forcing tropical convective disturbances is documented through a statistical analysis of satellite-derived OLR and ERA5 reanalysis. The forcing mechanism and the ...
A Heuristic Elastoplastic Damage Constitutive Modeling Method for Geomaterials: From Strength Criterion to Analytical Full-Spectrum Stress–Strain Curves
Publisher: ASCE
Abstract: This paper presents an elastoplastic damage constitutive modeling method in the thermodynamic framework for geomaterials. The model within this method starts from a strength criterion and shall well describe the full-spectrum ...
