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

ABRAMCZYK Jacek

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 plan(..)

THAUMASITE NON-SULPHATE ATTACK AT AMBIENT TEMPERATURE AND PRESSURE

Barbara SŁOMKA-SŁUPIK/ Adam ZYBURA

One of the products of concrete sulphate corrosion, besides gypsum and ettringite, is thaumasite. The thaumasite is a very dangerous, non binding crystalline phase, which is forming at the expense of C-S-H phase. There was a conviction that the conditions required for the formation of thaumasite in concrete are: source of calcium silicate, sulfate ions, carbonate ions and a very wet, cold (below 15°C) environment. The corrosion of concrete caused by the external source of sulphate ions during wh(..)

RESEARCH ON THE NEW CFRP PRESTRESSING SYSTEM FOR STRENGTHENING OF RC STRUCTURES

Bartosz PIĄTEK/ Tomasz SIWOWSKI

The paper presents a research on the new Polish CFRP prestressing system for strengthening of reinforced concrete structures. The system is called Neoxe Prestressing System II (NPS II). NPS II consists of two main elements: a special steel anchorages mounted on both ends of a single CFRP strip and a tensioning device. The anchorage is made of two steel plates. CFRP strip end is fixed between steel plates through bonding by epoxy resin and gripping by bolts. The tensioning device compatible with (..)

SURFACE BLAST-CLEANING WASTE AS A REPLACEMENT OF FINE AGGREGATE IN CONCRETE

Wojciech KUBISSA/ Roman JASKULSKI/ Tamás SIMON

In the article the possibility of using a surface blast-cleaning waste as a replacement of fine aggregate in concrete manufacturing was presented. Concretes with w/c ratio 0.6 and 300 kg/m3 dosage of cements: CEM I 32.5R and CEM II/B-V 32.5N were tested. The quite high value of the w/c ratio resulted in good compactibility of the mixtures without use of plasticizer. The replacement rate of the fine aggregate (0–2 mm) with copper slag (CS) was 33%, 66% and 100% respectively. Concretes of the same(..)

VALIDATION OF THE FIB 2010 AND RILEM B4 MODELS FOR PREDICTING CREEP IN CONCRETE

George C. FANOURAKIS

Creep strain, a requirement of the concrete design process, is a complex phenomenon that has proven difficult to model. Although laboratory tests may be undertaken to determine the creep, these are generally expensive and not a practical option. Hence, empirical code-type prediction models are used to predict creep strain. This paper considers the accuracy of both the relatively new international fibModel Code 2010 and RILEMModel B4, when compared with the actual strains measured on a range of c(..)

INNOVATIVE STEEL FIBERS AND THEIR EFFECT ON FIBER DISTRIBUTION IN BEAMS - EXPERIMENTAL INVESTIGATIONS

Michael HUSS/ Nguyen Viet TUE

This contribution presents experimental investigations on fiber reinforced concrete (FRC). A new type of straight steel fibers (company Feel Fiber) with a length of 60 mm was used. 12 beams with a length of 6 m, a height of 0.4 m and a width of 0.5 m were produced, in order to determine the fiber distribution along them. The beams differ in the manufacturing method (cast in layers or from one side), the fiber content and the way of fiber addition. After concretes hardening, slices were cut of th(..)

APPLICATION OF POTENTIOSTATIC MEASUREMENTS ACCORDING TO PN-EN 480-14 IN ASSESSMENT OF THE EFFICIENCY OF REINFORCEMENT PROTECTION AGAINST CORROSION BY CONCRETE WITH ADDITION OF FLY ASHES

Katarzyna DOMAGAŁA/ Andrzej ŚLIWKA

Replacing part of the cement in the concrete with fly ash - products of solid fuel burning, requires testing, including the degree of the reinforcement protection against corrosion provided by concrete. The paper presents a comparison of the results of the tests of the effectiveness of corrosion protection of reinforced concrete with the addition of calcareous fly ash. Tests were conducted by two electrochemical methods. Results obtained by potentiostatic measurement on reinforcement inserts dep(..)

WIND INFLUENCE ON A BUILDING WITH THE NATURAL SMOKE REMOVAL SYSTEM

Małgorzata KRÓL/ Aleksander KRÓL

The natural smoke removal is a common way of protection of the escape routes in Poland. The operation of such systems is based on the phenomenon of buoyancy. The intensity of this effect depends on the temperature difference between smoke and ambient air. The second factor influencing the natural smoke flow inside a building is wind. The wind influence is significantly important for buildings equipped with smoke removal windows. However, also the other natural smoke removal systems could be affe(..)
