Uplift Bearing Tests and Calculations of Belled Piles in Loess of Arid Regions [PDF]

, 2004
The field prototype tests have been carries out for under-reamed piles bearing uplift loading in the loess of droughty area. In these tests, uplift displacement and horizontal displacement of under-reamed piles bearing uplift loading and horizontal ...

Shaking Table Tests and Numerical Analysis of Rocking Vault‐Shaped Segmental Piers Equipped With an Annular Double Sliding System

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT To enhance the structural robustness of bridges, a rocking arch‐shaped segmental pier with a double sliding system was previously proposed as a low‐cost solution to protect bridges in developing countries. The rocking behavior is triggered by halting the sliding motion, which increases the horizontal load‐bearing capacity and limits ...

Machine Learning‐Driven Classification and Production Capacity Prediction of Tight Sandstone Reservoirs: A Case Study of the Taiyuan Formation, Ordos Basin

Energy Science &Engineering, EarlyView.
On the basis of core and log data, a Bayesian‐Optimized Random Forest model achieved 92.76% accuracy in classifying tight sandstone reservoirs. A gray relational analysis‐derived evaluation index shows > 80% consistency with actual gas zones. ABSTRACT Tight sandstone gas (TSG), an unconventional oil–gas resource, has heterogeneous reservoirs ...

Design and experimental analysis of a new shear connector for steel and concrete composite structures [PDF]

, 2006
This work presents the design of a new shear connector and the corresponding results obtained on push-out tests. This new shear connector consists on a steel rib with indented cut shape that provides resistance to longitudinal shear and prevents ...

Resonance and Psychic Affirmation: A Comparison of Hartmut Rosa's and Daniel Haybron's Conceptions of Human Happiness

Constellations, EarlyView.
ABSTRACT The paper compares Hartmut Rosa's resonance theory of “the good life” and Daniel Haybron's psychic affirmation theory of “happiness,” which he differentiates, as a descriptive notion, from “well‐being” as an evaluative notion. Haybron suggests that a central determinant of happiness has to be the somewhat reliable occurrence of positive ...

Design of plate and screw anchors in dense sand:failure mechanism, capacity and deformation [PDF]

, 2019
Plate and screw anchors provide a significant uplift capacity and have multiple applications in both onshore and offshore geotechnical engineering. Uplift design methods are mostly based on semi-empirical approaches assuming a failure mechanism, a normal

Desegregationist Pan‐African Spiritual Strivings: Du Bois, the Black Church and the Critique of Imperialism*

Journal of Religious History, EarlyView.
Abstract This article argues that W. E. B. Du Bois grounded his seminal conceptualisation of “the Negro church” in a Pan‐Africanist challenge to how Christian reformers and missionaries' usage of “Darkest Africa” as a metaphor for modern urban vice and poverty denigrated Africa and the African diaspora while promoting a segregated, imperialist version ...
