BEAUTY OF HISTORIC URBAN CENTRES – EVOLUTION IN CONSERVATION THEORY

Teresa BARDZINSKA-BONENBERG/ Magdalena BĄCZKOWSKA

Abstract The paper aims to investigate if the changing principles in the protection of historic urban spaces arose as a result of evolving rationale of modern architecture and town planning over the last two centuries. The research was performed using a chronological comparison of the literature, source texts and analyses of graphic materials. Considerations include the concept of beauty of a city upgraded by its reconstruction and conservation, in the perspective of the 19th century great theor(..)

HERITAGE AND INNOVATION IN SERBIAN 21ST CENTURY ARCHITECTURE – GENUINE TRADITIONAL BUILDING TECHNIQUES

Predrag MILOŠEVIĆ/ Vladimir MILOŠEVIĆ/ Grigor MILOŠEVIĆ

Abstract The social integration of people, the common belief of a particular group of people, contributed to the creation of a very fine and sincere architecture, which celebrated the habits and lifestyles of a particular community. National, traditional architecture is not a style, but rather, a glimpse of the world and life, the nature and genius loci, attitude towards life processes and materials, towards climate and authenticity. Traditional construction and building techniques help us estab(..)

STRUCTURE OF ARCHITECTURE – TENSEGRITIES IN THE CONSTRUCTION OF ARCHITECTURAL SPACE

Piotr POLINCEUSZ

Abstract Computer techniques allow the digital recording of any spatial form, which significantly changes designing methods. The possibility of the use of computer animation in the analysis of the designed shape allows the digital recording of the changing structure. The paper focuses on the future use of the structures and their development and presents ways of applying tensegrity structures and of space extraction characterizing the architecture. The classification of structural variations is (..)

SHEAR BUCKLING RESISTANCE OF CANTILEVER GIRDERS WITH CORRUGATED WEB

Witold BASIŃSKI

Abstract The study reports investigations into shear buckling resistance of the corrugated web of cantilever SIN girders. Experimental tests were conducted on ten SIN girders with the web height of 500, 1000, 1250 and 1500 mm made to 1:1 scale. The tests confirmed the advantageous effect of support stiffeners of cantilever girder parts on shear buckling resistance. Load-displacement paths of global displacements in cantilevers of SIN girders were analysed. The Finite Element Method was used to c(..)

RHEOLOGY OF MORTAR WITH PORTLAND-LIMESTONE CEMENT CEM II/A,B-LL IN RELATION TO PROPERTIES OF CEMENT

Małgorzata GOŁASZEWSKA

Abstract The paper presents the results of rheological research, conducted to examine how the properties and composition of cement affects the yield stress and plastic viscosity of Portland limestone cements. Portland limestone cements used in the research were obtained by mixing four Portland cements of various chemical and phase compositions with two limestones of different origin, in an amount of 6, 10, 20 and 30% of cement mass. The yield stress and plastic viscosity were determined using th(..)

MECHANICAL PROPERTIES OF CEMENT MORTAR WITH GRAPHENE OXIDE

Małgorzata KRYSTEK

Abstract These days, nanotechnology has already influenced many fields of science and technology, including civil engineering. Cementitious composites incorporating various nanomaterials have emerged as novel materials with improved microstructure, mechanical properties and durability. Over the past decades, graphene oxide has appeared as one of the most promising nanomaterials for civil engineering applications. However, the effect of graphene oxide addition on the properties of cementitious co(..)

EVALUATION OF ECOLOGICAL CONCRETE USING MULTI-CRITERIA ECOLOGICAL INDEX AND PERFORMANCE INDEX APPROACH

Wojciech KUBISSA/ Roman JASKULSKI/ Jiajian CHEN/ Pui-Lam NG/ Wioletta GODLEWSKA/ Pavel REITERMAN

Abstract This paper proposes a new method of rational and quantitative assessment of ecological concrete in terms of the ecological impact and engineering performance. The concrete mix is evaluated through the multi-criteria Ecological Index (EI) and Performance Index (PI) approach. The EI accounts for the impact of the concrete on environment including the carbon emission and raw materials usage, whereas the PI accounts for the engineering performance of the concrete such as compressive strengt(..)

THE EFFECTS OF DEAD LOADS IN CANTILEVER CONCRETING BRIDGES

Czesław MACHELSKI

Abstract Cantilever concreting technology is one of the modern methods of constructing concrete long-span bridges. Characteristic feature of those bridges is the long-term span deflection resulting from the rheological processes in the concrete and in the pre-tensioning steel. It can also be caused by the material deterioration, e.g. concrete cracking, as well as the changes in the bridge structure, such as the support settlements. The aggregate result of bridge exploitation are the changes in i(..)

ANALYSIS OF THE WIDTH OF PROTECTION ZONE NEAR A WATER SUPPLY NETWORK

Małgorzata IWANEK/ Paweł SUCHORAB/ Łukasz SIDOROWICZ

Abstract A protection zone near the water supply network belongs to the proposals of limiting negative results of potential breakages of buried water pipes. Water leaking from a damaged pipe can create swallow holes or hollows, dangerous especially in the urban areas. The proposed zone is an area on the soil surface along a buried water network, where the outflow of water could be expected after a potential failure of the pipe. The infrastructure in this zone should be carefully planned to limit(..)

THE COMPARATIVE ANALYSIS OF MUNICIPAL SOLID WASTE MANAGEMENT IN THE EIGHT CITIES OF UKRAINE

Nonna PAVLIUK

Abstract A simplified solid waste management system has existed for many years in Ukraine being. The system factually coming to MSW collection and their removal to landfills and dumps. This has resulted in accumulation of 223 million tons MSW on territory of more than 8.5 ha. Signing on 27th June 2014 EU-Ukraine Association Agreement obliged Ukraine to approximate legislation to EU demands in the Field of Waste Management [1]. On 8th November 2017 National Waste Management Strategy has been acce(..)

FABRICATION AND CHARACTERISATION OF CHITOSAN/COCONUT FIBER COMPOSITE MEMBRANES FOR ELIMINATING CU2+ AND PB2+ FROM AQUEOUS SOLUTIONS

Thi-Cam-Trang TRUONG/ Manh-Ha BUI/ Dang-Khoa NGUYEN/ Takaomi KOBAYASHI

Abstract Coconut fiber was chemically modified by NaOCl/NaOH, and then was composited through a cross-linking reaction with glutaraldehyde. The chitosan/coconut fiber (CTS/CF) composite membranes were prepared at various ratios of coconut fiber (CF) and then tested to determine their ability to eliminate aqueous heavy metals. The results showed that CTS/CF composite membranes having CF ratio of 80 wt% exhibited good mechanical strength as 89.8 MPa. In the elimination experiment of heavy metal io(..)

USE OF THE MACROMODEL DNS/SWAT TO CALCULATE THE NATURAL BACKGROUND OF TN AND TP IN SURFACE WATERS FOR THE RAC PARAMETER

Paweł WILK/ Paulina ORLIŃSKA-WOŹNIAK

Abstract Total nitrogen (TN) and total phosphorus (TP) get into surface waters from both natural and anthropogenic sources. Anthropogenic sources have been relatively well recognised but the natural emmission of nutrients into the rivers, in the case of many catchments, remains a mystery. The paper describes the possibility of using a tool, the Macromodel DNS/SWAT (Discharge Nutrient Sea/Soil and Water Assessment Tool), to estimate the concentration and load of natural background (Natural Pollut(..)
