LRFD Calibration of Facing Limit States for Soil Nail Walls
Publisher: ASCE
Abstract: This paper presents the results of load and resistance factor design (LRFD) calibration of the facing limit states for soil nail walls. The current AASHTO facing load model and a modified model together with the AASHTO ...
Analysis of Soil-Steel Bar Mat Pullout Models Using a Statistical Approach
Publisher: American Society of Civil Engineers
Abstract: Steel bar mat is a common reinforcing material in mechanically stabilized earth (MSE) walls. The current method to calculate the pullout capacity of these materials is an empirical-based formulation found in AASHTO and ...
Influence of Selection of Soil and Interface Properties on Numerical Results of Two Soil–Geosynthetic Interaction Problems
Publisher: American Society of Civil Engineers
Numerical Model for Reinforced Soil Segmental Walls under Surcharge Loading
Publisher: American Society of Civil Engineers
Abstract: The construction and surcharge loading response of four full-scale reinforced-soil segmental retaining walls is simulated using the program FLAC. The numerical model implementation is described and constitutive models for ...
Calibration of Resistance Factors for Load and Resistance Factor Design of Internal Limit States of Soil Nail Walls
Publisher: American Society of Civil Engineers
Abstract: A general approach for calibration of resistance factors for load and resistance factor design (LRFD) of pullout and tensile failure internal limit states of soil nail walls is presented. The calibration of resistance ...
Closure to “Improved Simplified Method for Prediction of Loads in Reinforced Soil Walls” by Tony M. Allen and Richard J. Bathurst
Publisher: American Society of Civil Engineers
Numerical Study of Reinforced Soil Segmental Walls Using Three Different Constitutive Soil Models
Publisher: American Society of Civil Engineers
Abstract: A numerical finite-difference method (FLAC) model was used to investigate the influence of constitutive soil model on predicted response of two full-scale reinforced soil walls during construction and surcharge loading. ...
Improved Simplified Method for Prediction of Loads in Reinforced Soil Walls
Publisher: American Society of Civil Engineers
Abstract: The Simplified Method as reported in AASHTO and Federal Highway Administration (FHWA) manuals has been demonstrated to give poor predictions of unfactored reinforcement loads and strains, especially for geosynthetic ...
Calibration of Soil-Steel Grid Pullout Models Using a Statistical Approach
Publisher: American Society of Civil Engineers
Abstract: Steel grids in the form of bar mat and welded wire mesh are a common reinforcing material in mechanically stabilized earth (MSE) walls. This paper uses a large database of laboratory steel grid pullout tests from multiple ...
Statistical Evaluation of the FHWA Simplified Method and Modifications for Predicting Soil Nail Loads
