"Abstract
Portal frames are the most commonly used structural forms for single-story industrial structures. For structures of this type, an unsuitable layout plan can increase total cost of construction; hence a suitable layout plan is of importance to achieve an economical design. This may require several trial designs. The optimization study presented here examines some key geometric and material parameters of industrial portal frame structures with different over head cranes capacities. The key parameters considered herein are: span of portal frame, portal frame spacing, overhead crane capacity and material properties of the single and double bay portal frames. The internal forces and deflections are calculated under the applicable gravity (considering the action of both crane and its load) by using elastic first-order static analyses, utilizing the finite element method. The current study examines the function of each of the above-mentioned parameters and presents the optimum parameters in terms of weight per unit area of portal frame. The results are presented in graphical form suitable for the preliminary stages of design of industrial portal frame structures with overhead cranes."

Industrial building design is based on developing a built environment for secondary sector activities which is based on undefined building typology. The client would do his inventions and ask for a certain built form according to the space requirements of functions that would lead to a productive manufacturing of his invention.
The hard work for production needs a work-oriented environment which is also economical and sustainable. The built construction should be environment-friendly that avoids widespread of pollution.
There is a requirement for good recreational spaces to aid a peaceful mindset for working people in midst of constructing different and new products.
The built environment should be made healthy and accommodate adequate services and ventilation. Skylights are very observed architectural elements of industrial building design since the space requirements are huge and it's difficult for light to enter through openings hence Trusses as roofing is very suitable and customizable.
Separate zone for power and tanks have to be provided.
Transportation is a challenge to be encountered with a strong priority as it has to be less congested, more productive and environment-friendly.
Globalization is an important factor for positioning industrial sites.
Entrepreneurship and industries build on each other together.

Steel structural elements with web-tapered I cross section, are usually made of welded thin plates. Due to the nonrectangular shape of the element, thin web section may be obtained at the maximum cross section height. The buckling strength is directly influenced by lateral restraining, end support and initial imperfections. If no lateral restraints, or when they are not effective enough, the global behavior of the members is characterized by the lateral torsional mode and interaction with sectional buckling modes may occur. Actual design codes do not provide a practical design approach for this kind of elements. The paper summarizes an experimental study performed by the authors on a relevant number of elements of this type. The purpose of the work was to evaluate the actual behavior of the web tapered beam-columns when applying different types of lateral restraints and different web thickness.

This article outlines the phenomenon of West Germany’s new universities for the masses. Seldom have so many universities of such size been built so quickly as in the Federal Republic of Germany in the 1960s and 1970s. Nearly 40 new universities were established across the country. It is a known fact that, from a political point of view, the priority was to provide as much space as possible quickly and cheaply. Following the concept of the functional city and the logic of increased efficiency by concentration, the vast majority of the new university complexes were constructed as large-scale structures outside of historic city centers. Architects seized the opportunity and designed the publicly financed large-scale complexes as urban utopias on a small scale, as I am going to show drawing mainly on examples in Bochum, Marburg, Berlin, Bielefeld and Constance. A key consideration – beyond efficiency – was the issue of flexibility. Inspired by systems theory, architects developed megastructures and building systems that would allow the academic communities to modify its buildings according to their needs in the future. However, the expectations that these New Universities might, due to their size and complexity, develop the same dynamism as historic towns, that were perceived to have ‘grown organically’, were fulfilled to a very limited extent only. Nonetheless, the mass universities are impressive testimony to the political, technical and urban planning spirit of the 1960s.

EN 1990 presents load factors for the building, whereas EN 1991-3 presents the load factors for crane - supporting structures. Within most industrial buildings, there is no clear separation of the crane supporting structure and the building. The paper presents an approach on how to determine the correct load factors for these type of buildings.
The paper also focuses on how to cope with these factors, in case of retrofitting existing (Mill) buildings. Within the Netherlands, there is a special code for retrofitting of existing buildings (NEN8700), however, this code only specifies how to deal with factors presented within the EN1990. How to deal with EN1991-3 factors is explained within this paper.

Steel structural elements with variable cross section, made of welded plates, are largely used in the construction industry for both beams and columns in accordance with the stress and stiffness demand in the structure. These types of elements are mainly used for the design of singles storey frames with pitched roof rafters and pinned column base. Rafters and columns can be designed as tapered members made of steel welded plates, respecting the bending moment diagrams for gravitational load combination. Although they are partially restrained against out of plane buckling by side-rails and roof purlins cooperating with sheeting, in current design practice it is quite difficult to evaluate their influence.
This paper deals with nonlinear elastic-plastic analysis and experimental tests performed on tapered beam-columns, parts of portal frames, subjected to both bending moment and compressive axial force. Failure of such members may occur by in-plane bending, local buckling and combination between these two, for members with low non-dimensional slenderness. While for members with intermediate and high non-dimensional slenderness, flexural–torsional buckling, local buckling and combination of these two may occur in function of the web slenderness.
Numerical results will be compared with experimental tests, obtained for a relevant number of specimens, in order to check the reliability of the numerically determined ultimate capacity of the elements. The influence of both lateral and torsional restraints applied on the beam-column will also be discussed.

With the development of science and technology in the field of structural engineering and also in civil engineering, it is possible to observe the adaptation of pre-engineered buildings in both industrial and residential construction sectors. In this paper, pre-engineered steel building will be design with different parameter using software Staadprov8i and analyzed with different loads on building i.e. dead load, live load, collateral load, wind load and load combinations on building .The main objective of this work is to understand the concepts of PEB and find the least possible weight of structure and various displacement or significance of forces in each direction which will help the structure to be safe and stable. The pre-engineered construction concept involves pre-engineered structure and quality construction systems which will help to minimize the use of cost and time.

The year 1972 was a turning point in the history of architecture because of the demolition of the Pruitt-Igoe housing estate and thus became the symbolic beginning of the end of modernism. At the same time, in Poland, the housing estate called “Za Żelazną Bramą” (Behind the Iron Gate) was put in use and became the model example of the socialist modernism and the construction industry and its “housing factories” began their activities on a mass scale. The urbanism of the 1970s and the 1980s, still controversial today because of its functional and aesthetical limitations, recently became an object of fascination reawakened by F. Springer’s books and – on the other hand – an object of critical reflection based on late Polish translations of J. Jacobs and R. Venturi works. The paper analyzes current landscape of block housing estates in terms of their social, technical and functional evaluation in relation to contemporary urban theories, showing some developmental prospects and possible “return of the blocks of flats” and the prefabricated construction industry.
