Structural Analysis and Simulation of Innovative Composite Building Consisting of LGS and Load Bearing Ferrocast Wall Panels Using FEM
Get PDFIn the construction of any structure, the most important factor considered today are cost of construction and ability of the building to resist loads and earthquakes. Research is going on about various precast composite technologies to get a structurally strong system yet with reduced time and cost of construction, thus making it an affordable structural system for modular construction. Considering these factors, light gauge steel or commonly known as cold formed steel and precast ferrocement composite structures are gaining popularity in the Indian construction industry. This article is an attempt to review structural behaviour of innovative use of LGS and Ferrocement, sandwich panel composite construction. In the present research work, Finite Element analysis is done for typical residential building made of precast ferrocement panels combined with light gauge steel composite structure. Finally, stresses in the ferrocement element are checked with experimental values thus determining the load carrying capacity of the structure subjected to dead, live and seismic loads. Overall proving this load bearing composite construction system to be more effective with respect to speed of construction, cost of construction and affordability at the same time enhanced structural performance. Thus, a practically enhanced solution to substitute the conventional RCC structure is possible using this LGS Ferrocast/ferrocement composite construction technology. The assumption for this composite technology is that all ferrocement structural components are factory made in custom sizes under strict quality control as to achieve desired permissible stresses

Deep convolutional neural network-based transfer learning method for health condition identification of cable in cable-stayed bridge
Get PDFThe cables are extremely important and vulnerable components in the cable-stayed bridges. Because cable tension is one of the most crucial structural health indicators, therefore, assessing the cable condition based on the cable tension is a major interest in the structural health monitoring (SHM) of the cable-stayed bridges. This paper aims to develop a deep convolutional neural network (DCNN)-based transfer learning method that is integrated with a continuous wavelet transform (CWT) for the health condition identification of the cables in a cable-stayed bridge using the one-dimensional time series cable tension data. For this purpose, the CWT is adopted to convert the cable tension to the images of a time-frequency representation. The last three new layers emerged in the pre-trained DCNN model, which is called AlexNet, as a new learning framework to use for the identification of the cable condition. The performance of the proposed DCNN model is examined using several statistical measures that include accuracy, sensitivity, specificity, precision, recall, and the F-measure. The results show that the proposed DCNN model gives superior accuracy (100%) for the identification of the undamaged cables and the damaged cables based on the cable tension data
كتابة التّورية وخطاب التعريّة في "عدوس السّرى" لإبراهيم الكونيّ
Get PDF This article is intended to highlight the biographies the aspects of the biographies narrator′s personal experience revelation, by revealing the entire life experiences: psychological, cultural, intellectual and ideological experiences in the author’s life. In addition, the article deals with the entire themes implied in this biography discourse by meditating it, persevering to recognize its content and defining its concepts through the available textual strategies that approximate this discourse and interpret its themes.The article is based on the hypothesis that the reason for which the authors, the novelists in particular, are interested in writing down their biographies is desire to experience presenting their mere biography for recognition before the reader that used to read their imaginative texts so that the reader has a view over the author′s personal life
Determination of the dynamic response due to the collision of adjacent structures as a function of the variation of the shear wave velocity
Get PDFThis article studies the coupled effect of the collision of adjacent buildings and the soil-structure interaction on the dynamic responses in terms of displacement and impact force. To illustrate the proposed procedure, an example of two 8-storey reinforced concrete buildings subjected to the 1941 el Centro earthquake was considered. The procedure consists in solving the dynamic equation of motion by Newmark's method using a program under matlab. The parameters of the soil-structure interaction are introduced by the impedance equations in the equation of motion. The analysis of the results obtained revealed that even if the two structures have identical characteristics, the variation of the shear wave speed completely changes their response in displacement and in impact force which can distort the dimensioning of the seismic joints
Synthesis, characterization of Zinc oxide and assessment of electrical DC conductivity properties
Get PDFPolymer composites are widely used in electrical devices, sensor materials, electromagnetic interference (EMI) shielding, and other applications. Composites may be customized for any intended application by changing the ratios of the polymeric components. Polyaniline (PANI) is not as sensitive as metal oxides toward gasoline species, and its negative solubility in organic solvents limits its packages, however it's miles suitable as a matrix for instruction of engaging in polymer nanocomposites. Therefore, there has been increasing hobby of the researchers for the education of Nano composites based totally on PANI The fuel for the production of nanometal oxide comes from naturally occurring sources. The weight percentages of such generated metal oxides are altered during chemical polymerization with polyaniline. Composites of polyaniline cellulose and varying weight ratios of Zinc oxide (ZnO) are produced. In synthesised Polyaniline cellulose/ZnO composites, the formation of polymers and their interactions with metal oxides are investigated using Ultraviolet (UV)-vis, Fourier-transform infrared spectroscopy (FTIR), and X Ray Diffraction. The surface morphology of the composites is studied using Scanning electron Microscopy. The characteristics of the specified composites are investigated using electrical dc conductivity electrical conductivity
نظرية النّص في ضوء نظريّة التّأثير
Get PDFIn this paper, we aim to highlight an important angle in the approach to literary text, one of many angles that form the so-called "theory of text," specifically the Theory of Aesthetic Response of Wolfgang Eiser, through which he sought to consolidate his critical vision in a collection of his writings particularly his book "the Act of Reading,". This study, therefore, gives the reader a central idea of what this theory is about on one hand, and indicate the extent of its ability and effectiveness in reaching the aesthetic side in reading the literary text on the other hand
أداء السياق الوظيفي في انسجام القصائد السبع العلويات لابن أبي الحديد (القصيدة السادسة نموذجاً)
Get PDFAs one of the most significant issues in textual linguistics, Context theory plays a dynamic role in text coherence. This is achieved by referring the text to the network of semantic relations in the outer world and by examining how the meanings in the text are connected based on their positions. As one of the dimensions of coherence, context-based perspective is based on the analysis of how meaning is disseminated in the elements of the text and it explains the interaction of the text with larger semantic structures which include ideological, cultural and social dimensions to present the integrated text system. Due to its thematic unity and artistic potential, in addition, due to the religious and cultural heritage of the Abbasid era, the "Alawiat" odes of Ibn abi al-Hadid, is considered suitable for examining the context. Based on the fact, we have selected the sixth ode from the collection, which is the longest and the most famous ode, and we have examined the function of context in the coherence of the ode, in the two parts: lexical part (phoneme, morpheme, syntax and lexeme levels) and non-lexical (intellectual, emotional and cultural levels). Then, we continued the research via presenting sample verses based on descriptive-analytical method.Based on the studies, it was concluded that the sixth ode has a coherent and solid texture; its elements are inextricably linked with the context. Praise, as the main subject of the text, influences the way words are selected and is responsible for propagation of the meanings from the beginning of the poem to the end. In addition, the connection of this verbal event (the same text) with the thoughts and ideas of the poet and his commitment to religious and cultural heritage influences the selection of strategies appropriate to the situation and reveals the unspoken words of the text and helps to better understand it
حيوان" الجاحظ في محكّ السّيمياء بحث في سيميائية التواصل
Get PDFThe present study examines the animal book by Al-Jahiz from a semiotic perspective. We chose this science because it studies the ways the sign works in literature and in other fields. It helps to understand texts, formats, and verbal and non-verbal sign systems. Thus, semiotics is a general logic that accommodates all phenomena and seeks to formulate abstract rules.As for the expansion of this science, we must clarify it through its pairing with the issue of communication that goes beyond language at the level of verification to other formsPerhaps the most important of theseat this level is the sign by which an animal communicates among its species.The Index also where we communicate with the Divine Self from a Mu'tazila’s point of view through the animal that belongs to a medium of Bayān.Al-Jahiz made it comprehensive and comprehensive, containing everything indicative that cannot be deduced from animal and inanimate objects.This is what Eric Buyssens collected under the spontaneous or natural signs. So, this book is based on a semiotic dualism, which is the duality of the outward and the inner. Thus, Al- Bayān was a metaphor for a world in which creatures descend, as indicative of an eternal signifier, which is God
