RISFlow Updating in Real-Time Flood Forecasting Based on Runoff Correction by a Dynamic System Response Curve
Publisher: American Society of Civil Engineers
Abstract: In order to improve the accuracy of real-time flood forecasting, a new accurate and efficient real-time flood forecasting error correction method based on a dynamic system response curve (DSRC) is developed. The dynamic ...
Euler–Bernoulli Pile Element for Nonlinear Buckling Analysis of Single Piles in Slope
Publisher: ASCE
Abstract: Piles are sometimes unavoidably embedded in slopes for supporting buildings on hills. In contrast to a pile on a horizontal ground, a pile in slope is acted on by additional sliding force from the slope, impairing its ...
Efficient Line-Element Method for the Second-Order Analysis of Steel Members with Nonsymmetric Thick-Walled Cross Sections
Publisher: ASCE
Abstract: When designing steel members with nonsymmetric cross sections, it is essential to consider twisting effects when performing stability checks via second-order analysis according to the ANSI/AISC 360-22. Existing line-element ...
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. ...
Some Aspects of Recent Research on the Qinghai-Xizang Plateau Meteorology
Publisher: American Meteorological Society
Abstract: The Qinghai-Xizang (Tibet) Plateau has a profound influence on atmospheric circulation patterns on all time and space scales. This report constitutes a short summary of work being performed at the Lanzhou Institute of ...
Analysis of Compressive Characteristics of Asphalt Mixture under Freeze-Thaw Cycles in Cold Plateau Regions
Publisher: American Society of Civil Engineers
Abstract: Low average temperature, large temperature difference, and continual freeze-thaw (F-T) cycles are the typical climatic characteristics of cold plateau regions. F-T cycles and the asphalt-aggregate ratio of an asphalt mixture ...
Second-Order Direct Analysis of Domelike Structures Consisting of Tapered Members with I-Sections
Publisher: American Society of Civil Engineers
Abstract: A new and advanced beam-column element, namely the curved tapered-three-hinges (TTH) beam-column element, is proposed in this paper. The present element can perform large deformation analysis and explicitly simulate the ...

Efficient Beam–Column Finite-Element Method for Stability Design of Slender Single Pile in Soft Ground Mediums
Publisher: ASCE
Abstract: Slender single piles are extensively used but susceptible to buckling when embedded in soft ground mediums. Owing to the complexity of soil properties, the soil-structure interaction (SSI) response is sometimes very ...
Three-Dimensional Analysis of Nonlinear Pile–Soil Interaction Responses Using 3D Pile Element Model
Publisher: ASCE
Abstract: Due to the complicated geological conditions and complex loads, the pile–soil interaction is a three-dimensional (3D) and highly nonlinear problem. Conventional numerical models have deficiencies to model the nonlinear ...
