A Model for Shear Strength of FRP Bar Reinforced Concrete Beams without Stirrups

open access: yesAdvances in Civil Engineering, 2020
The shear failure of a reinforced concrete beam generally occurs when the principal tensile stress near the neutral axis is equal to or greater than the tension strength of concrete.

Initiating Market Formation Through Local Policy Innovation: Plot Handover as a Driver for Circular Construction

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The transition to circular construction suffers from uncertainties related to costs, market realities, supply, regulations and expertise using secondary materials in building projects. Uncertainties are large, and resolving them needs policy interventions.

Circular Innovations in Complex Systems: A Blueprint of Four Design Archetypes

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Circular innovations (CI), defined as the redesign of products, services or practices to minimise waste, reduce resource use and regenerate natural systems, are essential for advancing the circular economy. Despite growing recognition, their deployment in systems of linked parts with unpredictable interactions (complex systems) remains limited

Review and prospects of shear test of bolted rock joints

open access: yesDeep Underground Science and Engineering, EarlyView.
The laboratory shear test equipment, test method, and numerical simulation of bolted rock joints were summarized. The shortcomings and limitations of the current research were analyzed, and the research prospects were proposed. Abstract Rock bolting is a critical approach in geotechnical engineering for supporting weak rocks.

Ductility of Reinforced Concrete Beams

open access: yesCVR Journal of Science & Technology, 2015
Concrete structures are designed by satisfying two criteria namely, safety and serviceability. Safety criterion checks whether the structure is safe in carrying the designed load or not. Serviceability criterion checks whether the developed deflections and crack widths are within the permissible limits or not.
