Analysis of reinforced concrete shells with transverse shear forces [PDF]
Journal of Structural Engineering 136, 7 (2010) 837-848, 2013 This research investigates the simultaneous effect of in-plane and transverse loads in reinforced concrete shells. The infinitesimal shell element is divided into layers (with triaxial behavior) that are analyzed according to the smeared rotating crack approach. The set of internals forces includes the derivatives of the in-plane components.

Experimental theoretical modelling of concrete shrinkage in massive structures [PDF]
E3S Web of ConferencesIn spite of the high culture of modern construction, the majority of massive structures erected in different countries of the world cannot avoid shrinkage cracks during the curing process, which negatively affect both the stiffness and durability of such

Predictive Stress Modeling of Resilient Modulus in Sandy Subgrade Soils
Infrastructures, 2023 The mechanical properties of pavement materials are crucial to the design and performance of flexible pavements. One of the most commonly used measures of these properties is the resilient modulus (Er). Many different models were developed to predict the

Predicting Confinement Effect of Carbon Fiber Reinforced Polymers on Strength of Concrete using Metaheuristics-based Artificial Neural Networks [PDF]
arXiv, 2023 This article deals with the study of predicting the confinement effect of carbon fiber reinforced polymers (CFRPs) on concrete cylinder strength using metaheuristics-based artificial neural networks. A detailed database of 708 CFRP confined concrete cylinders is developed from previously published research with information on 8 parameters including ...

Improving the performance of concrete using 3D fibres [PDF]
, 2012 This paper examines whether 3D fibre reinforcement can improve the toughness and flexural strength of concrete, when compared to equal dosage of straight steel fibres. This work was carried out to determine structural qualities that may lead to potential

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Introduction The use of radioactive materials in the United States has been tightly regulated by the Nuclear Regulatory Commission and other entities for many decades. In 2015, however, the Joint Commission began to require hospital‐based nuclear medicine departments to conduct shielding designs and evaluations for radioactive material areas ...
