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

Business 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

Experimental investigation on reinforcement performance of concrete slab with three-dimensional high-strength steel-wire-mesh

Case Studies in Construction Materials
Three-dimensional high-strength steel-wire-mesh (3D-HSWM) has been proven as a potential alternative of reinforcement material of steel wire mesh in the non-slab concrete members.

Numerical Analysis of Reinforced Concrete Slab with Subsoil

Civil and Environmental Engineering, 2020
Abstract The article deals with the interaction of a reinforced concrete slab with subsoil. The paper contains a non-linear analysis based on an experiment of reinforced concrete slabs with dimensions 2000 x 2000 mm and thickness 150 mm. A steel mesh with a diameter of 8/100 mm was used as reinforcement.

Modelling of reinforced concrete slabs in fire [PDF]

Fire Safety Journal, 2018
Abstract A numerical procedure for the thermal analysis of RC slabs at elevated temperatures is the subject of this study, where the moisture increase due to the so-called moisture clog occurring in the cooler parts of reinforced concrete (RC) slabs is introduced as well.

Semi‐analytical solution for the stability of deep vertical shaft considering time‐dependent rock‐structure interaction

Deep Underground Science and Engineering, EarlyView.
A novel cavity contraction solution and multilayer shaft wall model were developed to analyze deep shaft stability, considering rock viscosity, support structures, and water pressure, with successful validation through a Hulusu Coal Mine case study.

Reducing the shear reinforcement in reinforced concrete beams and slabs

Magazine of Concrete Research, 1965
Summary The shear tests reported in the present paper were carried out in Stuttgart from 1961 to 1963. The mechanism of failure at ultimate shear load is explained in terms of the truss analogy, and the ratio between the width of the compression flange and the thickness of the web is shown to have a considerable influence on the inclination of the ...

REINFORCED CONCRETE ORTHOTROPIC SLABS CALCULATION

East European Scientific Journal, 2022
The formula for determining the coefficient that allows to determine the torsional stiffness of the rods is suggested. In this case, the system of perpendicular beams becomes equivalent to a solid slab. Verification of the formula in the numerical implementation of the technique in software complexes shows almost complete coincidence of the deflections

EVALUATION OF FIRE ENDURANCE OF SELF COMPACTED CONCRETE SLAB REINFORCED WITH STEEL FIBER REINFORCEMENT AND STEEL BARS

Diyala Journal of Engineering Sciences, 2012
The effect of steel fiber on the deflection of self- compacted slabs under fire (6000c) was investigated in this study. Three specimens were tested experimentally and numerically ( by using sophisticated finite element programme ANSYS 7.0) to determine ...
