Reinforcement learning in populations of spiking neurons [PDF]

open access: yes, 2008
Population coding is widely regarded as a key mechanism for achieving reliable behavioral responses in the face of neuronal variability. But in standard reinforcement learning a flip-side becomes apparent.

Reinforcement of metal structures by external reinforcement by gluing high-strength fiber-reinforced systems: analytical approach

open access: yesTransfer of Innovative Technologies, 2021
Ukraine's construction heritage includes numerous examples of the use of metal structures, especially those used in industrial buildings and high-span structures. The use of metal structures in construction is due primarily to their mechanical properties. They are frost-resistant and can withstand temperatures down to -65 degrees, hard, durable, strong

Punching strength of flat slabs with shear reinforcement: considerations about the control perimeters [PDF]

open access: yesRevista IBRACON de Estruturas e Materiais
In structural design practice and scientific research on flat slabs, estimating the punching shear resistance of slab-column connection with shear reinforcement involves checking the shear stress acting on a control perimeter outside the shear-reinforced

EXTERNAL REINFORCEMENT OF CONCRETE STRUCTURES USING COMPOSITE MATERIALS

open access: yesVestnik Tomskogo gosudarstvennogo arkhitekturno-stroitel'nogo universiteta. JOURNAL of Construction and Architecture, 2018
The paper describes the main directions of non-metallic composite application in concrete reinforcement. The development routes of the structural analysis with composite reinforcement are formulated. The reinforced concrete structure combines the elastic reinforcement element with an adhesive composition having inelastic properties.

The Structural Use of Recycled Aggregate Concrete for Renovation of Massive External Walls of Czech Fortification

open access: yesBuildings, 2022
The use of recycled aggregate concrete is mainly negatively affected by its poorer mechanical and long-term properties. However, there are few structural applications for which recycled aggregates can be used.

Applying bi-directional evolutionary structural optimisation method for tunnel reinforcement design considering nonlinear material behaviour

open access: yes, 2014
In the empirical methods for reinforcement design of underground excavations, an even distribution of rock bolts is generally recommended. This work proves that this design is not necessarily optimal and shows how the state-of-the-art reinforcement ...

Shear resistance of reinforced concrete beams with and without steel fibres. [PDF]

open access: yes, 1981
The fabrication and placement of conventional shear rein- forcement are time consuming and costly and its use in thin structural concrete members is often impractical.

Experimental study of the behaviour of RC corbels strengthened with CFRP sheets

open access: yesCase Studies in Construction Materials, 2018
This paper presents an experimental study of behaviour of externally strengthened short reinforced concrete (RC) corbels by carbon fibre reinforced polymer (CFRP) fabrics. For this purpose, twelve specimens were prepared and tested.
