Model Uncertainty of Eurocode 7 Approach for Bearing Capacity of Circular Footings on Dense Sand
Publisher: American Society of Civil Engineers
Abstract: This paper presents a critical evaluation of the model factor M = qu,m/qu,c for Eurocode 7 calculating the bearing capacity of circular footings on dense sand, where qu,m = measured capacity and qu,c = Eurocode 7 calculated ...
Evaluation of Stress-Dependent Methods for the Punch-Through Capacity of Foundations in Clay with Sand
Publisher: American Society of Civil Engineers
Abstract: This paper compiled 159 centrifuge tests for foundations in clay with interbedded sand where punch-through failure was observed. The accuracy of initial- and failure-stress-dependent methods was quantified by the mean and ...
Elastoplastic Constitutive Model of Sand–Gravel Composites Considering the Whole Shearing Process
Publisher: ASCE
Abstract: In the framework of generalized plasticity theory, this paper presents a new elastoplastic model to characterize complicated softening/hardening and dilation/contraction behaviors of sand–gravel composites in triaxial ...
Model Uncertainty for Predicting the Bearing Capacity of Sand Overlying Clay
Publisher: American Society of Civil Engineers
Abstract: In this paper, 62 centrifuge tests are collected from the literature and used to perform a statistical evaluation of the model factor for conventional methods to calculate the bearing capacity of dense sand overlying clay. ...
Statistical Analyses of Model Factors in Reliability-Based Limit-State Design of Drilled Shafts under Axial Loading
Publisher: American Society of Civil Engineers
Abstract: This study compiles 320 static-load tests to quantify the model factors in reliability-based limit-state design of drilled shafts under axial loading. At ultimate limit-state, the model factor is defined as the ratio of ...
A Probabilistic Risk Assessment Approach for Surface Settlement Caused by Metro Tunnel Construction Using Credal Network
Publisher: ASCE
Abstract: The epistemic uncertainty of geological condition, hydrological condition, and human factors causes the risk assessment result of metro construction to be imprecise. To reveal the epistemic uncertainty, a probabilistic ...
Self-Sensing Stress-Absorption Layer with Carbon Nanotubes Grafted onto Basalt Fibers
Publisher: ASCE
Abstract: Fiber-reinforced emulsified asphalt (FEA) is widely used in asphalt pavement structures as a stress-absorption layer. This study aimed at developing a multifunctional fiber-reinforced emulsified asphalt (MFEA) by empowering ...
Expanded Database Assessment of Design Methods for Spread Foundations under Axial Compression and Uplift Loading
Publisher: ASCE
Abstract: This paper compiles two expanded databases—NUS/SpreadFound/919 and NUS/RockFound/270—to evaluate the calculation methods of foundation capacity, where the number is the number of load tests collated. The mean (bias) and ...
