Feasibility of using neural networks to obtain simplified capacity curves for seismic assessment

The selection of a given method for the seismic vulnerability assessment of buildings is mostly dependent on the scale of the analysis. Results obtained in large-scale studies are usually less accurate than the ones obtained in small-scale studies. In this paper a study about the feasibility of using Artificial Neural Networks (ANNs) to carry out fast and accurate large-scale seismic vulnerability studies has been presented. In the proposed approach, an ANN was used to obtain a simplified capacity curve of a building typology, in order to use the N2 method to assess the structural seismic behaviour, as presented in the Annex B of the Eurocode 8. Aiming to study the accuracy of the proposed approach, two ANNs with equal architectures were trained with a different number of vectors, trying to evaluate the ANN capacity to achieve good results in domains of the problem which are not well represented by the training vectors. The case study presented in this work allowed the conclusion that the ANN precision is very dependent on the amount of data used to train the ANN and demonstrated that it is possible to use ANN to obtain simplified capacity curves for seismic assessment purposes with high precision.info:eu-repo/semantics/publishedVersio

The changes in 19th century European hospital architecture. Selected examples

In their long history, hospitals have undergone numerous transformations, both in terms of function and organization, as well as architecture and space. At first they served as shelters for pilgrims, the homeless and the ailing poor. It was not until the turn of the 18th century and 19th century that they began to be understood as organized public institutions devoted solely to the purpose of curing the sick. At the same time, first European clinics began to emerge, which combined the didactic function of universities of medicine with the medicinal function of an ordinary hospital. Until today, there have survived the majority of 19th century European hospital buildings. Many of them still boast a clear composition of spatial structure and valuable forms of architectural detail. Development in medicine, however, has brought about an evolution in health care and consequently functional and spatial programs of hospitals have also began to change. Today, many historical European hospitals experience substantial problems connected with the adaptation to new requirements in terms of equipment necessary in modern-day medicine. Is therefore the passing of historical hospital architecture unavoidable…

Neural network-based formula for the buckling load prediction of I-section cellular steel beams

Cellular beams are an attractive option for the steel construction industry due to their versatility in terms of strength, size, and weight. Further benefits are the integration of services thereby reducing ceiling-to-floor depth (thus, building’s height), which has a great economic impact. Moreover, the complex localized and global failures characterizing those members have led several scientists to focus their research on the development of more efficient design guidelines. This paper aims to propose an artificial neural network (ANN)-based formula to precisely compute the critical elastic buckling load of simply supported cellular beams under uniformly distributed vertical loads. The 3645-point dataset used in ANN design was obtained from an extensive parametric finite element analysis performed in ABAQUS. The independent variables adopted as ANN inputs are the following: beam’s length, opening diameter, web-post width, cross-section height, web thickness, flange width, flange thickness, and the distance between the last opening edge and the end support. The proposed model shows a strong potential as an effective design tool. The maximum and average relative errors among the 3645 data points were found to be 3.7% and 0.4%, respectively, whereas the average computing time per data point is smaller than a millisecond for any current personal computer

Masonry compressive strength prediction using artificial neural networks

The masonry is not only included among the oldest building materials, but it is also the most widely used material due to its simple construction and low cost compared to the other modern building materials. Nevertheless, there is not yet a robust quantitative method, available in the literature, which can reliably predict its strength, based on the geometrical and mechanical characteristics of its components. This limitation is due to the highly nonlinear relation between the compressive strength of masonry and the geometrical and mechanical properties of the components of the masonry. In this paper, the application of artificial neural networks for predicting the compressive strength of masonry has been investigated. Specifically, back-propagation neural network models have been used for predicting the compressive strength of masonry prism based on experimental data available in the literature. The comparison of the derived results with the experimental findings demonstrates the ability of artificial neural networks to approximate the compressive strength of masonry walls in a reliable and robust manner.- (undefined

The 19th century Medical Clinic of Collegium Medicum of the Jagiellonian University in Krakow An outline of conservation problems in the light of requirements of a modern university hospital

W drugiej połowie XIX i na początku XX w., wśród licznych założeń ogrodowych oraz bogatej zieleni ulicznej, na terenie dawnego przedmieścia Wesoła w Krakowie utworzony został niezwykle wartościowy zespół monumentalnych klinik Collegium Medicum Uniwersytetu Jagiellońskiego. Od początku swego istnienia był odzwierciedleniem swojej epoki - jej osiągnięć technicznych oraz poglądów estetycznych na sposób kształtowania architektury szpitalnej. W swojej ponad dwuwiekowej historii przeszedł wiele zmian, stopniowo rozbudowując strukturę oraz zasięg działalności. Do dzisiaj przetrwała większość zabytkowych budynków, które nadal współtworzą działający na tym terenie krakowski Szpital Uniwersytecki. Mogą wykazać się jasną kompozycją układu przestrzennego oraz pięknymi formami detalu architektonicznego. Objęte ochroną konserwatorską, stanowią jeden z bardziej interesujących zespołów architektoniczno-urbanistycznych położonych w centrum Krakowa, nadający tożsamość temu miejscu i utrwalający jego szpitalny charakter. Rozwój medycyny powoduje jednak ewoluowanie poglądów na metody leczenia, a w konsekwencji zmianie ulegają również programy funkcjonalno-przestrzenne szpitali. W dniu dzisiejszym wiele krakowskich klinik ma w związku z tym duże problemy związane z adaptacją do wymogów współczesnego szpitala akademickiego.In the second half of the 19th and at the beginning of the 20th century, an unusually valuable complex of monumental clinics of Collegium Medicum of the Jagiellonian University was created among numerous garden complexes and lush street greenery, in the area belonging to the former Wesoła suburb in Krakow. Since the very beginning it reflected its epoch - its technical achievements and aesthetic views on the way of shaping hospital architecture. During the two centuries of its history, it has undergone many alterations, gradually expanding both its structure and the range of its activity. The majority of historical buildings, which still constitute the Krakow University Hospital functioning in this area, have survived until the present day. They can display clear composition of spatial layout and beautiful architectural detail. They are under conservation protection as they constitute one of the most interesting architectural and urban complexes, situated in the centre of Krakow, adding identity and preserving the hospital character of the place. However, the advance in medicine triggers evolution of opinions concerning methods of treatment, and consequently the functional and spatial programmes in hospitals also have to change. Nowadays, many clinics in Kraków have to cope with serious problems connected with their adaptation to satisfy the requirements of a modern university hospital
