FULL AND PARTIAL STRUCTURES OF HISTORICAL ROOF TRUSSES IN ASSESSMENT OF VOLUME OF TIMBER USED FOR CONSTRUCTION

Magdalena CHYLEWSKA-SZABAT

Abstract Rafter framing is the basic roof frame that, through the trusses, transfers the load from the roofing to the main supports of the building. The construction material of these structures is usually wood. The development of roof framing construction for wider and wider covers has caused an increased demand for construction timber for their construction. This paper points to this economic aspect based on an example of a geometric pattern of a rafter framing based on repetitive construction(..)

ON ORIENTATION OF VISUALLY IMPAIRED PEOPLE IN PUBLIC SPACE

Beata KOMAR

Abstract The topic of this paper focuses on orientation of visually impaired people in public space. The purpose of the paper is to show the ways visually impaired people move and therefore, to show the barriers which hinder them to get someplace. An important element is to increase social awareness of the quality of public spaces so that they could be adapted to every user. The paper was written on the basis of literature analyses and the author’s own observation.

IN SEARCH OF ARCHITECTURAL FORM – IDENTIFICATION OF PLACE. DESIGN OF A CITY BENCH IN STUDENTS’S PROJECTS (WORKS)

Ewa RACZYŃSKA-MĄKOWSKA/ Romuald FAJTANOWSKI

Abstract Identification of a PLACE through conscious application of given forms correlated with spatial conditions is a demanding task for a designer who needs to take into consideration the context and history of the space they are supposed to function within. The authors of this study have presented four application examples for a city bench as a form interacting with a selected space in Bydgoszcz (350-thousand inhabitants, a town in the north-west Poland, situated at the confluence of two riv(..)

RANDOM STRENGTH PARAMETERS OF STEEL CORRUGATED WEBS AND THEIR INFLUENCE ON THE RESISTANCE OF SIN PLATE GIRDERS

Witold BASIŃSKI/ Zbigniew KOWAL

Abstract In the study, the results of statistical investigations into random strength parameters of steel used to manufacture corrugated webs of SIN plate girders were discussed. The investigations were conducted on samples randomly collected from twenty SIN girders. The corrugated web of the girders was 2, 2.5 and 3 mm in thickness. The girders had been examined before statistical investigations were conducted. Based on the analysis, coefficients of variation of yield strength VRe=D(Re)/E(Re) a(..)

INFLUENCE OF SELECTED ADMIXTURES ON THE MICROSTRUCTURE OF RENOVATION PLASTER MORTARS

Wacław BRACHACZEK

Abstract In the environment in which the renovation plaster mortars are exposed to moisture, followed by the crystallization of salt, their required durability is obtained by aeration. Aeration increases the porosity and resistance to salt crystallization, significantly changing the properties of plaster mortars. The paper presents the results of research on the influence of aeration and hydrophobizing admixtures on the porosity and pore size distribution in renovation plaster mortars. It was fo(..)

DETERMINATION OF MECHANICAL PROPERTIES OF METHYL METHACRYLATE ADHESIVE (MMA)

Abstract Experimental testing of epoxy adhesives, which are commonly used in civil engineering for the strengthening of existing structures with composite products have been a topic of limited studies. It was due to the damage which usually occurred not in the adhesive layer but in the strengthened material. Recent studies have shown that the choice of an adhesive significantly affects the load-bearing capacity of the entire joint. The paper presents the results of strength tests of a selected m(..)

HEALTH AND SAFETY PERCEPTION OF CONSTRUCTION WORKERS IN SAUDI ARABIA

Muizz O. SANNI-ANIBIRE/ Abubakar S. MAHMOUD/ Mohammad A. HASSANAIN/ Faleh ALMUTAIRI

Abstract Construction is a high-risk industry due to the high rates of accidents/fatalities recorded annually in various countries. Health and safety (HS) is a major concern of the construction industry. More so, for developing countries where HS cultures are yet to become fully established. In such situations, the perception of construction workers is a viable approach to assess the performance of HS. This study investigated the HS conditions in Saudi Arabian construction sites from the perspec(..)

THERMAL IMPROVEMENT IN RESIDENTIAL BUILDINGS IN VIEW OF THE INDOOR AIR QUALITY – CASE STUDY FOR POLISH DWELLING

Monika BLASZCZOK/ Andrzej BARANOWSKI

Abstract The widespread thermal improvement in residential buildings involves not only the insulation of outdoor walls but also window replacement. In Poland it is the residents of individual premises who manage the replacement and in order to keep their heating bills low, they seek airtight solutions to minimize the cooling of premises due to air infiltration. In this situation the indoor air quality is not considered at all and no exchange of used air and fresh air occurs. Unawareness on the p(..)
