A NON-LINEAR SHAPED ARCHITECTURE IN URBAN SPACE

Krystyna JANUSZKIEWICZ/ Karol G. KOWALSKI/ Krystyna JANUSZKIEWICZ/ Karol G. KOWALSKI

The paper deals with the modernization and adaptation to the new features of existing objects in the urban fabric. In the twenty-first century the digital design tools, which are interfaced with the production of computer technology, have opened the new opportunities that not only are shaping the architectural objects, but also interferencing in the buildings’ structures. The selected objects are examined, which have been implemented in the European cities centers, and the new design approaches,(..)

TAKING UP RESIDENCE NEAR THE GARDEN AS THE SUBSTITUTE OF THE GARDEN-CITY IDEA

Sylwia KRZYSZTOFIK/ Sylwia KRZYSZTOFIK

Garden city is an idea regarded as one of the reasons for the spontaneous sprawl of buildings around the city. The paper compares the assumptions described in the book “Garden Cities of Tomorrow” with the way of the investment implementation on the outskirts of Łódź, in the buffer zone of the Łagiewnicki Forest. The analysis of the spatial structure of the newly urbanized open areas, made on the basis of aerial photography and introduction of geodesic division shows that the emerging housing dev(..)

SILESIAN CONURBATION AS A POLYCENTRIC STRUCTURE OF URBAN DISTRICTS

Michał STANGEL/ Agnieszka CIELIŃSKA/ Łukasz HARAT/ Michał STANGEL/ Agnieszka CIELIŃSKA/ Łukasz HARAT

The Silesian conurbation consists of cities, which in many aspects function as one metropolitan organism. This paper is an attempt to characterise the structure of the Silesian conurbation not as composed of cities, but as a system of districts, in the context of the theory of polycentric systems and the importance of quarters for modern urban areas. The authors present a model of the Silesian Conurbation as a set of quarters of various characteristics: housing estates, local centres, industrial(..)

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

Yaarub Gatia ABTAN/ Hassan Falah HASSAN/ Yaarub Gatia ABTAN/ Hassan Falah HASSAN

The solution of using glass fiber reinforced polymer (GFRP) bars, as reinforcement in concrete structures to overcome the problems created by steel corrosion, is now widely accepted because of both its non-corrosive nature and good results shown by large investigation efforts. In this paper twenty tests had been conducted on reinforced concrete wall specimens of (800 mm height x 450 mm width x 50 or 70 mm thickness effective dimensions). Four specimens were reinforced with steel bars to be consi(..)

RELIABILITY ANALYSIS OF RIGID PILE CAPS USING AN ITERATIVE STRUT-AND-TIE MODEL

José Milton de ARAÚJO/ José Milton de ARAÚJO

The aim of this work is to present a new strut-and-tie model for design of rigid pile caps based on the concept of magnified area under the column. In this magnified area, compressive stresses have been reduced enough not to cause crushing of the struts. An iterative algorithm is used to determine the required depth of the magnified area. The model considers both failure by crushing of the compressed struts and by yielding of the tie reinforcement. A large number of experimental results availabl(..)

RELIABILITY-BASED EVALUATION OF LOSS DUE TO DISTRIBUTION OF NONSTRUCTURAL COMPONENTS IN HEIGHT

Leila HAJ NAJAFI/ Mohsen TEHRANIZADEH/ Leila HAJ NAJAFI/ Mohsen TEHRANIZADEH

Structural and nonstructural components incorporate simultaneously and correspondingly in modern probabilistic performance evaluation to make decision making parameters which is usually economic loss in a predefined level of probability. However, far greater investment, relatively limited seismically design information and dependence of nonstructural components’ normative quantities to some architectural, economic and social features contribute to exceeded loss amounts and uncertainties under no(..)

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

Maria MANSO/ Maria MANSO/ João Paulo CASTRO-GOMES/ Michal MARCHACZ/ Marcin GÓRSKI/ Leszek DULAK/ Rafał ZUCHOWSKI

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, variet(..)

DAYLIGHT PREDICTION IN INDIVIDUAL FLOORS USING WELL INDEX

Mahsan MOHSENIN/ Jianxin HU

This research is focused on assessing daylight performance in different floors based on the building proportion. Previous studies showed that atrium with the same Well Index (proportion) will receive the same daylight. This study aims to examine the relation between daylight in different floors of a building, using Well Index. Using DIVA for Rhino and DesignBuilder as the optimized daylight and energy simulation tools, this paper employs Daylight Autonomy (DA) and thermal performance as measured(..)

ESTIMATION OF THE SEASONAL DEMAND FOR COOLING BASED ON THE SHORT-TERM DATA

Dorota BARTOSZ/ Aleksandra SPECJAŁ

The paper analyzes the possibility of using the energy signature method based on the linear regression to determine the seasonal energy demand for cooling and ventilation in the office building. The “extended” energy signature method (H-m method) was described and applied. In accordance with Standard (EN 15603) the estimation of energy consumption for cooling can be performed for a period shorter than the entire season, but data range must be appropriate to obtain the correct accuracy of the res(..)

  The requirements for the inspection of heating systems have been introduced in the Energy Performance Act. Thermal diagnostics of the system is an evaluation of the technical conditions of the heating and hot water installations, due to their energy efficiency and reliability of obtaining the required internal temperature in the building and delivery of the right amount of domestic hot water at the proper temperature. Data obtained from the diagnostics are useful for proper energy-efficient op(..)
