RISSystem Identification through Nonstationary Response: Wavelet and Transformed Singular Value Decomposition—Based Approach
Publisher: American Society of Civil Engineers
Abstract: The full-scale data measured from tall buildings and long-span bridges are usually nonstationary due to transient earthquake ground motion, sudden changes in wind speed and/or direction, or time-varying motion of vehicles. ...
Numerical Analysis of Second-Order Mean Wave Forces by a Stabilized Higher-Order Boundary Element Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A stabilized higher-order boundary element method (HOBEM) based on cubic shape functions is presented to solve the linear wave-structure interaction with the presence of steady or slowly varying velocities. The m-terms ...
Displacement-Dependent Earth Pressures on Rigid Retaining Walls with Compressible Geofoam Inclusions: Physical Modeling and Analytical Solutions
Publisher: American Society of Civil Engineers
Photographic Study on Two-Phase Flow Patterns of Water in a Single-Side Heated Narrow Rectangular Channel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Visualized experimental observation on flow patterns during flow boiling of water under single-side heated and fluid-inlet subcooled conditions in a vertical narrow rectangular channel with the ...
Near-Real-Time Hybrid System Identification Framework for Civil Structures with Application to Burj Khalifa
Publisher: American Society of Civil Engineers
Abstract: This study proposes a near-real-time hybrid framework for system identification (SI) of structures using data from structural health monitoring systems. To account for both stationary/weakly nonstationary response under ...

Simulation of Hurricane Wind Fields for Community Resilience Applications: A Data-Driven Approach Using Integrated Asymmetric Holland Models for Inner and Outer Core Regions
Publisher: American Society of Civil Engineers
Abstract: Accurate modeling of the damage caused by hurricanes making landfall to physical infrastructure relies on the accurate modeling of temporally and spatially varying wind fields. However, wind field measurements from past ...
Influence of Raised Groundwater Level on the Stability of Unsaturated Soil Slopes
Publisher: American Society of Civil Engineers
Abstract: The response of unsaturated soil slopes subjected to raised groundwater levels is generally governed by undrained shear strength. A series of unconsolidated undrained triaxial tests was conducted on reconstructed specimens ...
Numerical Solutions of Two-Dimensional Navier–Stokes Equations Based on a Generalized Harmonic Polynomial Cell Method With Non-Uniform Grid
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It is essential for a Navier–Stokes equations solver based on a projection method to be able to solve the resulting Poisson equation accurately and efficiently. In this paper, we present numerical solutions of the 2D ...
