RISProbabilistic Behavior and Variance-Based Sensitivity Analysis of Reinforced Concrete Masonry Walls Considering Slenderness Effect
Publisher: ASCE
Abstract: Inherent uncertainties associated with masonry structures result in large scatter in experimentally or analytically predicted behavior. Rigorous investigation of uncertainties in the structural behavior of masonry structures ...
Formulation, Implementation, and Validation of a 3D Damage-Plasticity Cohesive-Interface Model with Multiple Yield Surfaces for Cyclic Modeling of Mortar Joints
Publisher: ASCE
Abstract: The mechanical behavior of mortar joints can be described by means of the cohesive interface element in the mesoscale modeling of masonry structures. In this paper, a novel three-dimensional (3D) constitutive model for the ...
Influence of Flow Width on Mean Velocity of Debris Flows in Wide Open Channel
Publisher: American Society of Civil Engineers
Abstract: Debris flow in a wide open downstream channel has a significant transverse velocity component that strongly influences its mean longitudinal velocity. Investigation of observation data of debris-flow surges at Jiangjia ...
Closure to “Out‐of‐Plane Inelastic Buckling and Strength of Steel Arches” by Yong‐Li Pi and N. S. Trahair

Real-Time Movement-Based Traffic Volume Prediction at Signalized Intersections
Publisher: ASCE
Abstract: The traffic volume of each movement at signalized intersections can provide valuable information on real-time traffic conditions that enable traffic control systems to dynamically respond to the fluctuated traffic demands. ...
Machine Learning–Based Hysteretic Lateral Force-Displacement Models of Reinforced Concrete Columns
Publisher: ASCE
Abstract: Hysteretic lateral force-displacement (HLFD) models are important for efficient structural analysis under cyclic loading (e.g., earthquakes). This paper proposes a novel machine learning (ML)-based HLFD model, referred ...
Effects of Permanent Ground Deformation Patterns on Strain Demand of Pressurized Buried Continuous Steel Pipelines
Publisher: ASCE
Abstract: The structural integrity of buried pipelines is often threatened by permanent ground deformation (PGD) within the pipeline route. Oil and gas transmission steel pipelines, which usually traverse several kilometers, are ...
Residual Deformation-Based Performance Evaluation Method for CFST Piers Subjected to Vehicle Collision
Publisher: ASCE
Abstract: Concrete-filled steel tubular (CFST) piers have been applied in bridge structures due to their high bearing capacity, good ductility, and light weight. During their service life, CFST piers may suffer vehicle collision. ...
Study on Deformation Control of Large Deformation Tunnel in Soft Rock across Faults
Publisher: ASCE
Abstract: This study focuses on the area of large deformation of soft rocks across the fault in Dongmachang China to investigate support methods for fractured surrounding rocks Negative Poisson's Ratio (NPR) anchor cable support. ...
Finite-Element-Based Study on Girder Behavior and Load-Sharing of Shear-Connected Multigirder Prestressed Concrete Bridges
Publisher: ASCE
Abstract: This paper aimed to study the girder behavior and load sharing of multigirder prestressed concrete (PC) bridges using an efficient nonlinear analysis tool based on finite-element (FE) modeling. A newly developed nonlinear ...
