Identification of bending moment in semi-fixed beam
(Procedia Engineering, 2013)Paper presents procedure of identification of supporting moment in the statically indeterminable, partly fixed reinforced concrete beam. Examined beam is a part of reinforced concrete frame, where rate of fixing is subjected ... -
Frost resistant ceramics produced from local raw materials and wastes
(Procedia Engineering, 2013)The aim of this work was to analyse the possibilities to produce frost resistant ceramic body from local raw materials and wastes. Additional task is to investigate the influence of two waste materials (sawdust and milled ... -
Effect of dolomite limestone powder on the compressive strength of concrete
(Procedia Engineering, 2013)The purpose of this work is to describe the effect of fine ground dolomite limestone on important physic and mechanical properties of concrete. The present examinations indicate that the use of dolomite limestone as ... -
Possibility for stabilization of grounds and foundations of two valuable ancient cathedrals on weak soils in Baltic Sea region with grouting
(Procedia Engineering, 2013)In this paper are analysed deformations of ancient churches in Vilnius and in Koenigsberg (Kaliningrad) and possibilities for stabilization of its grounds with grouting. Foundations of both Cathedrals were constructed on ... -
Design of shear connection between steel truss and concrete slab
(Procedia Engineering, 2013)Composite steel and concrete trusses used in floor and bridge structures are analyzed with respect to shear connection between a steel truss and a concrete slab. Elastic and elastic-plastic behaviour of the shear connection ... -
Analysis of the time-dependent reliability index for deteriorating load-carrying members
(Procedia Engineering, 2013)The probability-based prediction and analysis of time-dependent survival probabilities and reliability indexes of non-deteriorating and deteriorating structural members exposed to extreme gravity and climate action effects ... -
Effects of the basaltic tuff additions on the properties, structure and phase composition of the ceramic tiles for interior wall facing
(Procedia Engineering, 2013)Basaltic tuffs are indispensable associated rocks during extraction of basalts, which are formed from igneous basalt fragments, cemented and compacted by volcanic glass and ash. The chemical and mineralogical composition, ... -
Development of a quality criteria system for facilities management services in Lithuania
(Procedia Engineering, 2013)Service quality management and evaluation is a very complex and problematic process. In order to improve the quality of services, it is necessary to understand the characteristics and features of services which are ... -
Impact assessment of lime additive and chemical admixtures on selected properties of mortars
(Procedia Engineering, 2013)Durability of the structure is still a problem, particularly in masonry. Contemporary European standards of masonry mortar are vague and leave insufficiency for the specification of requirements that should be fulfilled ... -
Uni-axial compression test of concrete-filled-steel-tube columns confined by tie bars
(Procedia Engineering, 2013)Concrete-filled-steel-tube (CFST) columns have been adopted due to its superior strength and ductility performance contributed by the composite action. However, this beneficial composite action cannot be fully developed ... -
Studies of RC beams made of recycling aggregate concrete strengthened with the HSC-HPC inclusions
(Procedia Engineering, 2013)This paper presents the studies of innovative RC flexural members made of recycled aggregate concrete strengthened by the local use of High Strength - High Performance Concrete. This concept of is based on precast concrete ... -
The framework of an optimization model for building envelope
(Procedia Engineering, 2013)Building design is an iterative process from the conceptual design up to the final process, so the use of computer-based tools here is vital. The purpose of this research was to investigate the most popular tools for ... -
Assessment of priority options for preservation of historic city centre buildings using MCDM (ARAS)
(Procedia Engineering, 2013)Numerous countries are trying to find the best method for suitable management of real estate objects that encompass both material value and cultural property. Cultural property can be defined as historical heritage in the ... -
Selection of efficient retrofit scenarios for public buildings
(Procedia Engineering, 2013)Over the past two decades, the importance of the management of existing buildings is continuously increasing with time. Refurbishment of buildings requires execution of various measures that have to be carefully chosen, ... -
Conventional stochastic sequences in reliability assessments and predictions of structural members
(Procedia Engineering, 2013)A simplification of probability based approaches on safety assessments and predictions of structural members is discussed. The modelling of time-dependent survival probabilities and reliability indexes of particular and ... -
Measuring and time variability of the sorptivity of concrete
(Procedia Engineering, 2013)The article presents measurements of sorptivity. They were performed not only, as usual, after 28 days, but also after longer periods of time (2, 3, 6, 9, 12, 24 months) on samples made of the same concrete. Four different ... -
The investigation of alkali – silica reactivity (ASR) of Lithuanian aggregates
(Procedia Engineering, 2017)The potential alkali-silica reactivity (ASR) of Lithuanian aggregates from five quarries was investigated using national chemical method, accelerated mortar bar test method RILEM AAR-2 (specimens 40×40×160 mm) and storage ... -
Impact of chemical and physical modification on thermoplastic characteristics of bitumen
(Procedia Engineering, 2017)In spite of strong competition of synthetic materials (including PVC, EPDM), bitumen remains the major component of most waterproofing materials. It makes up approx. 80% by weight of the final product. The characteristics ... -
Impact of recycled aggregates on selected physical and mechanical characteristics of cement concrete
(Procedia Engineering, 2017)The issue of using construction rubble was recognized in Europe not earlier than in the nineties of the twentieth century. This was due to economic and ecological considerations. However, recycled aggregate is characterized ... -
