When it comes to doubly curved surfaces in construction, especially shell structures, the skew ruled surfaces play a prominent role, because they are statically efficient and relatively easy to produce [1]. However, in order to fully exploit the design potential of this class of surfaces, conventional CAD programs do not provide adequate tools. Fro...

Presented research was intentioned to clarify the effects of thermal treatment (ageing) of reinforcing steel products on their mechanical and deformation properties. In order to determine the effect of temperature, samples were exposed to room temperature (reference samples) and a temperature of 100 °C in duration of 30, 60 and 120 minutes, res...

A hybrid method for the spatial discretization of two-dimensional domains is recently derived and applied to the problem of free vibrations of simply-supported singly curved shells. This new method follows from a tensor product of NURBS functions and a carefully selected series that satisfies boundary conditions a priori. The formulation unifies sp...

The paper presents the methodological approach for improvement of energy performance of public buildings in the process of partial refurbishment, having in mind the constrains that are originating from existing technological, material and stylistic characteristics. Being the carriers of wider social and historical connotations, these buildings are ...

In recent years, fast and simple acquisition of geospatial data, fast processing, and distribution is a trend that characterizes geoinformation technologies. The primacy of the acquisition is based on image processing technology and laser scanning. This paper attempts to answer how acceptable these technologies are incorporated into smartphones whi...

This paper aims to examine the state of undeveloped spaces in urban areas. The first part of the paper focuses on the state of the urban landscape's undeveloped spaces. To recognize their character and quality, the Narrative Spatial Analytics (NSA) method was proposed. It integrates three design research techniques which enable landscape designers ...

21st century architecture, in line with the rapid development of technology, could be read through many different architectural expressions and movements in just the first two decades, but they all aim the same - sustainability and energy efficiency. The decade-long process of building the Faculty of Architecture and Civil Engineering in Banja Luka...

Spatial intelligence is an important skill for students of technical faculties, especially those fields where the capacity for engineering thinking and creative expression is equally valued. The field of Architecture is emphasized here, and the issue of assessing the spatial abilities of architecture students and their improvement has often been ob...

For the design and construction of buildings in seismic areas the European Standard EN 1998-1:2004 offers two non-linear methods, namely: a non-linear pushover based static method and a nonlineardynamic method. This paper discusses those methods which differ from one another in respectto accuracy, simplicity and transparency. Non-linear static proc...

In this paper we used a new class of special functions and special polynomials which are solutions different Sturm Liouvile differential equations of second order. These functions form a basis of a space of square integrable functions over set of a real numbers. We investigated some properties of these polynomials and established some recurrence fo...
