At the bottom of canal, there are large deposits silt. During cleaning and scouring river bed, so-called by-product sediments formed. Landfills made along bed because it is a relatively close distance. preparation this paper, idea refers to examination sediment with additional binders see its application in road industry. The tests that will be presented paper are: granulometric composition soil, determination maximum volumetric mass at optimal humidity (Proctor's test), soil's bearing...

This paper presents an analysis of the stabilization different soil types using a hydraulic binder. A study was carried out on soils that can be classified into two groups: cohesive and non-cohesive soils. Clay medium low plasticity according to USCS classification were used as materials, while sandy material containing dust considered material. Samples taken from fifteen locations in Vojvodina province, Serbia. binder based cement lime. The amounts estimated at 3, 5, 7, 9%. In order...

The aim of the research presented in this paper is experimental confirmation numerically defined shapes Strut-and-Tie models, designed according to EN 1992-1-1 recommendations, and obtained from software “ST method”. Three reinforced concrete deep beams with openings were tested. Each them had same dimensions quality material characteristics. specimens, constructed as simply supported beams, loaded two concentrated forces tested for bending until failure. specimen was different reinforcement...

Quality assessment of stiffness and load-carrying capacity composite connections is great importance when it comes to designing timber–concrete structures. The new European regulation intended explicitly for structures has made a significant contribution this field, considering that until today there was no adequate design standard. Due the proposed general expressions determining with dowel-type fasteners, which are incapable describing most commonly applied engineering, scientific practice...

Preliminary notes

The paper deals with the influence of temperature changes on concrete pavement.Due to differences in upper and lower surface a slab, bending stress is created, resulting slab deformation.During process heating, difference between pavement created as result heat conduction.The has tendency expand (tense), whereas one does not alter its dimensions, which results generating stress.Concrete most commonly placed zones extremely heavy traffic load well at bus stops.The analysis was carried out...

The concept of circular economy has become an important topic during the last decade, because it offers a systems solution framework that creates closed-loop system to minimize waste and maximize resource efficiency in order achieve better balance harmony between economy, environment society. construction industry significant potential apply model since this is responsible for considerable global natural extraction solid production. Worldwide, more than 10 billion tons demolition are...

Experimental and computational research on the behavior of small-scale large-scale fiber-reinforced concrete (FRC) beams is presented in this paper. The experimental part included bending tests, which were conducted three 1.3 m long by 0.1 wide 0.15 high rectangular simply supported beams, test that was 12.8 0.2 two-chords girder. mixture designed with environmentally more justifiable supplementary materials (binder fibers), striving for sustainable excellence. To accurately predict...

This paper presents a proposal for determining Strut-and-Tie models of reinforced concrete plane elements. For the purposes analysis, computer program was developed and discrete topological optimization applied, using truss member design stress-strain state real member. The method can be used analysis part or whole it is particularly suitable usage in places sudden changes static and/or geometric characteristics members. general principle that compressed members replace parts element...

This paper presents the results of experimental research and numerical analysis three reinforced concrete deep beams with openings, designed by Strut-and-Tie method according to EN 1992-1-1 recommendations. All tested specimens were made in full size, same geometric characteristics quality materials. The specimens, constructed as simply supported beams, loaded two concentrated forces for bending until failure. Each specimen was different reinforcement layout determined parameter variation...

The method of capacity design requires the ductility reinforced concrete load-bearing elements and provides beam plasticity mechanism for a structure to absorb significant seismic energy. Indeterminate static systems are particularly suitable, where an indefinite number indeterminacy determines plastic hinges being forming, thus achieving favourable energy dissipation. In this paper, five-storey frame is designed two classes according regulations EN1992-1-1 EN1998-1.

This paper presents an estimation of ductility demands RC frames by using non-linear time-history analysis.RC with different number storeys, are designed according to the provisions EN 1992 and 1998 for two classes intensities seismic actions.Seismic response was assessed on three earthquake records procedure given in 1998.Ductility demand is estimated at global local level.These values were compared class, storeys intensity.The aim this point out influence of, not only design but also...

In this paper, the reinforced concrete wall member, statically simply supported, is analyzed and designed by Strut-and-Tie method in "ST method" program.The nonlinear behavior of member on simplified two-dimensional model with assumption plane stress state Abaqus program.For discretization part, 2-dimensional finite elements CPS4 are used, reinforcement modeled using basic truss elements.

This paper presents a design of reinforced concrete deep beam by means ofStrut-and-Tie method.Numerical analyzes were conducted with the "ST method" program, which automatically defines Strut-and-Tie models and dimensioning plane RC members.The opening was analyzed.Nodal zones model analyzed, as hydrostatic, "hand" calculation, nonhydrostatic, using program.The obtained results both approaches compared.

Seismic design according to European norms implies the of ductile rc structures.By confining concrete, ratio stress-strain is chaning and increases ductility.In Eurocode 2, a model confined concrete was proposed, in 8 an improved shown.The paper also analyzes compared values obtained strengths ultimate strains for both models as well their impact on global local seismic response case six-storey frame.

Concrete mixtures are made, or prepared with aggregates, binders and water, in some concrete chemical additives used to improve the properties of mixtures.The paper presents results testing crushed stone cement (CEM II / A-M (S-L) 42,5 R), water for production, admixtures (SIKA VISCOCRETE 3070 SIKA AER).The composition is shown second part paper, because due large number results, work divided into two parts.According test it can be concluded that tested materials satisfy described by SRPS standars.
