Coupled Macroelement Model of Soil-Structure Interaction in Deep Foundations
Publisher: American Society of Civil Engineers
Abstract: The principal objective of this study is the development and calibration of a macroelement model for soil-pile interaction under simultaneously applied lateral and vertical loads. Herein, we focus on cast-in-drilled-hole ...
Classification of Soft-Story Buildings Using Deep Learning with Density Features Extracted from 3D Point Clouds
Publisher: ASCE
Abstract: Soft-story buildings are seismically vulnerable during earthquakes. The identification of such buildings is vital in seismic risk mitigation to assess the seismic resilience of a given urban region. Several studies have ...
Data-Driven Computational Homogenization Method Based on Euclidean Bipartite Matching
Publisher: ASCE
Abstract: Image processing methods combined with scanning techniques—for example, microscopy or microtomography—are now frequently being used for constructing realistic microstructure models that can be used as representative volume ...
Multiphase Performance Assessment of Structural Response to Seismic Excitations
Publisher: American Society of Civil Engineers
Abstract: An alternative approach to the traditional method for performance assessment of structural systems is proposed. Denoted herein as the M-PARS method, this new approach is capable of tackling clusters of structural behavior ...
Data-Driven Approach to Predict the Plastic Hinge Length of Reinforced Concrete Columns and Its Application
Publisher: ASCE
Abstract: Inelastic response of reinforced concrete columns to combined axial and flexural loading is characterized by plastic deformations localized in small regions, which are idealized as plastic hinges. Under extreme events such ...
Data-Driven Models for Predicting the Shear Strength of Rectangular and Circular Reinforced Concrete Columns
Publisher: ASCE
Abstract: Predicting the shear strength of structural elements subjected to gravity loads and ground motions is an important component of seismic design. Among all primary structural components, the vital role of columns in load ...
Bayesian Joint State-Parameter-Input Estimation of Flexible-Base Buildings from Sparse Measurements Using Timoshenko Beam Models
Publisher: ASCE
Abstract: This paper presents a computationally efficient framework for the Bayesian identification of sparsely instrumented building structures that is amenable to rapid postearthquake condition assessment. Flexible-base Timoshenko ...
Effects of Roof Shape and Roof Pitch on Extreme Wind Fragility for Roof Sheathing
Publisher: ASCE
Abstract: Wind fragility curves for roof sheathing were developed for single-family building models to investigate the effects of roof shape and roof pitch on the wind performance of roof sheathing. For gable roofs, it was found ...
Modified Method for Accurate Evaluation of Overturning Limit on Restrainer-Reinforced Single-Column Pier Bridges
Publisher: American Society of Civil Engineers
Abstract: Single-column bridges are widely used for urban overpasses and highway bridges. Rising overturning incidents have exposed the vulnerability of this type of bridge, which is inherently susceptible to overturning collapse. ...
Risk-Optimal and Equitable Retrofitting Strategy Using a Siamese Graph Neural Network for Earthquake-Induced Landslide Hazards
Publisher: American Society of Civil Engineers
Abstract: Landslides pose a severe threat to road networks, particularly in hilly terrains, often exacerbated by triggering events such as earthquakes. Hence, it is crucial to comprehensively evaluate their risk and optimize retrofits ...
