ǂThe ǂimpact of a thermal insulation layer on the seismic performance of energy-efficient buildings
Stanislav Lenart, Siva Ram Karumanchi
Objavljeni znanstveni prispevek na konferenci
Oznake: energetsko učinkovite stavbe;toplotna izolacija;ekstrudirani polistiren (XPS);analiza končnih elementov;agregat iz penastega stekla;potresni odziv;energy-efficient buildings;thermal insulation;extruded polystyrene (XPS);finite element analysis;foamed glass aggregate;seismic response;
Energy-efficient homes are constructed with a continuous and uniform thermal envelope and are commonly built on top of a thermal insulation (TI) layer that encloses the entire building. Lightweight aggregates such as foamed glass aggregate, expanded clay aggregate, and extruded polystyrene (XPS) ins ...

Use of marginal and recycled fills for GRS structures
Stanislav Lenart, Siva Ram Karumanchi
Objavljeni znanstveni prispevek na konferenci
Oznake: ojačitev tal;ojačane polnilne strukture;GRS abutmenti;ostanki iz papirne industrije;rečne naplavine;soil reinforcement;reinforced fill structures;GRS abutments;residues from paper industry;river debris;
Marginal and recycled fills are increasingly being utilized in geosynthetic reinforced soil (GRS) structures like retaining walls and bridge abutments due to their cost- effectiveness and sustainability. Marginal fills, including locally available soils with less desirable engineering properties, ca ...

Increasing the confinement in railway track ballast layers
Stanislav Lenart, Siva Ram Karumanchi
Objavljeni znanstveni prispevek na konferenci
Oznake: balast;železniški tir;geosintetika;omejevalni tlak;test majhnega obsega;ballast;railway track;geosynthetics;confining pressure;small-scale test;
Insufficient effective confining pressure within the ballast layer can lead to the permanent rotation of grains, causing increased wear and abrasion. Augmenting confinement may not only mitigate ballast degradation but also enhance the overall performance of the track. The increased confining pressu ...

Deformation properties and performance evaluation of reused ballast with waste tire-derived aggregates
Stanislav Lenart, Siva Ram Karumanchi
Izvirni znanstveni članek
Oznake: ponovno uporabljen balast;guma;ciklični preprosti strižni preskusi;BBI;degradacija;reused ballast;rubber;cyclic simple shear tests;degradation;
The present study evaluates the shear strength characteristics, deformation properties, and degradation behavior of limestone-based reused ballast (RB) material by mixing crumbs of waste tire-derived aggregates (TDA), focusing on its suitability for railway infrastructure. Conventional large-scale d ...

Numerical evaluation of suction effects and groundwater table variations on long-term pavement subgrade performance
Siva Ram Karumanchi, Anirban Mandal, Stanislav Lenart
Izvirni znanstveni članek
Oznake: fleksibilen tlak;nenasičena tla;sesanje;metoda končnih elementov;flexible pavement;unsaturated soil;suction;finite-element method;
Over the past few decades, flexible pavements across the globe have seen a significant reduction in their service life due to climate changes. The flexible pavements with unsaturated sub- grades undergo volumetric changes during the drying and wetting phases, affecting their long-term deformation be ...
