STRUCTURAL BEHAVIOR OF NORMAL AND HIGH-STRENGTH CONCRETE WALLS REINFORCED WITH GLASS FIBER-REINFORCED POLYMER BARS UNDER ECCENTRIC LOAD

considered as references, while the others were reinforced with GFRP bars. The specimens were made using normal and high strength concrete. All specimens showed similarity in the structural behavior and load pattern, the results show that Steel reinforced walls have 28% higher ultimate load than corresponding GFRP reinforced walls, also an approximate linear increase in the failure load with increasing in flexural GFRP reinforcement in range from 40.4% to 98.8% for NSC walls and in range of 70% to 115.1

TESTS OF JOINTS IN AAC MASONRY WALLS

Abstract The paper presents the results of the Authors’ tests on the joints in AAC masonry walls. The shape of the tested element and the test stand were fitted innovatively based on the Authors’ own experience as well as on the literature overview and numerical analysis. Cracking morphology and mode of failure were investigated. The relationship between the load and displacement for different types of joins was compared. The obtained results were also compared to the results obtained on the

ACOUSTIC EVALUATION OF A NEW MODULAR SYSTEM FOR GREEN ROOFS AND GREEN WALLS

Environmental noise is a major problem that affects citizen’s health and comfort mainly in densely populated urban areas. There are some ways to reduce environmental noise pollution through the use of materials with good acoustic insulation properties in buildings envelope. Recent studies have shown that green surfaces, e.g. in the form of green roofs and green walls, can contribute to decrease noise levels. The aim of this research is to identify how factors such as substrate and plants

PREVENTING IRREGULARITY EFFECTS OF INFILLS THROUGH MODIFYING ARCHITECTURAL DRAWINGS

Experiences of past earthquakes show that some designed and constructed buildings by engineers have been damaged during earthquakes because of negative effects of infill walls. The main aim of this paper is to prevent the amount of overall detrimental effects of infill walls such as torsion and soft story in a conventional residential building based on seismic codes of some countries and to use the maximum potential of walls. The results show that building in construction condition may suffer

This paper will present different ways of energy activation in external walls with a special focus on the photovoltaic panels/modules (PV), the transparent insulation (TIM) and phase change materials (PCM). New materials can be included in the partition structure in different configurations such as a single or a bi-material component for improving thermal effects.

IMPACT OF ENVELOPE STRUCTURE ON THE SOLUTIONS OF THERMAL INSULATION FROM THE INSIDE

Abstract The article presents chosen issues related to the heat insulation of complex structure walls. Subjects covered in this study are building partitions that had been constructed in the so called “Prussian wall” technique and are located in the Upper Silesia region. Their technical condition as well as usable state are not satisfactory, especially in the light of thermal protection. One way of increasing their standard is insulating partitions. In case of historical monuments or rich

PARAMETRIC SHAPING OF CONSISTENT ARCHITECTURAL FORMS FOR BUILDINGS ROOFED WITH CORRUGATED SHELL SHEETING

The paper presents a method for a parametric shaping of innovative building free forms covered with corrugated steel shell roofs and flat glass elevation walls. Each shell roof is made of plane steel sheets folded in one direction and transformed elastically into spatial shape. The obtained shapes can be really diversified sectors of various ruled surfaces. Therefore there is a great need for creating such a method that leads to a fine integration of the shapes of a free form shell roof and

RISK ASSESMENT OF WATER VAPOR CONDENSATION IN WALL MADE OF HEMP-LIME COMPOSITE

The paper presents issues associated with moisture presence in the wall partitions. As the wall material a lime-hemp composite was selected. Materials containing organic components are sensitive to excessive amount of moisture. One of the most important sources of moisture in the walls is diffusive water vapor, which may condense inside the partition. An important parameter of wall material is water vapor permeability. Inappropriate indor air relative humidity and the temperature of the wall

Stiffness caused by small span, inclined RC slabs and perimeter infill walls of staircase, based on the staircase location and the number of structural bays could change mode shape and lead to torsion.

[4], with a few exceptions, all energy costs of the building are thermal by nature, since almost all the energy emitted in the house – mechanical, electrical or radiant passes into a thermal form before leaving the building. The heat-power energy in the low-rise buildings is generally lost in three main directions (Fig. 1): –through opaque enclosures (walls, floor, ceiling); –through translucent enclosing structures (windows, rooflights); –due to ventilation

BACTERIAL CHITINASES AND THEIR APPLICATION IN BIOTECHNOLOGY

Chitin, an insoluble linear β-1,4-linked polymer of N-acetylglucosamine, is the second most abundant polysaccharide in nature after cellulose. It is present in cell walls of several fungi, exoskeletons of insects and crustacean shells. Enzymatic hydrolysis of this polysaccharide is carried out in the presence of glycoside hydrolases-chitinases. They are produced by microorganisms, insects, plants, and animal, but it is the bacterial chitinases which play a fundamental role in degradation

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

1. INTRODUCTION As reported by Central Statistical Office of Poland (GUS), it is estimated that the number of dwellings in Poland amounts to 13.5 millions [1]. Until 1985 the erected buildings had been extremely energy consuming and often without thermal insulation. The time had been characterized by the lack of strict requirements concerning the maximum heat transfer coefficient in outdoor walls: during 1960s – (1.16÷1.42 W/(m2K)) and 1980s (0.75 W/(m2K))[2].

Subsequently these become unguided missiles that strike occupants, resulting in injuries. This paper presents an analysis of the crash performance of a typical bay table. The results provide some understanding of the table’s crash safety, giving an indication of its impact aggression. Table materials are characterised using quasi-static compressive tests. In
