Frame systems are commonly used in structural design. Beams and columns are essential in the design and analysis of these types of structures. Since no practical and generally recognized method has yet been developed to determine the failure loads of these systems, nonstructural components such as architectural walls are not usually taken into consideration in the analyses. In this study, the experimental failure loads and failure types of 30 partially or fully infilled steel frame systems were determined after testing these systems under reversed cyclic horizontal loading. After the analytical study was carried out, the failure loads and failure modes of the samples were obtained analytically using the equivalent strut tie method, and experimental and analytical results were compared.Key words: infilled steel frames, partially infilled frames, lateral load-carrying capacity, equivalent strut tie method.

An analytical study is performed to propose a simple expression for the fundamental period of vibration of concentrically braced steel frames. This work was carried out in the context of the development of the 2005 National Building Code of Canada (NBCC) and is mainly applicable to structures located in moderate and low seismic regions. Available field and test measurements of building periods are compared to analytical predictions. An empirical period formula is developed based on a survey of analytically computed building periods published in the literature. The influence of the 2005 NBCC design provisions on braced steel-frame periods is examined through a closed-form period solution and an extensive parametric study. Building periods are found to vary significantly with seismic hazard levels and soil conditions. An expression is tentatively proposed that provides reasonable lower-bound period estimates for most situations in Canada.

This research article focuses on the theme of violence and its representation by the characters of the novel “This Savage Song” by Victoria Schwab. How violence is transmitted through genes to next generations and to what extent socio- psycho factors are involved in it, has also been discussed. Similarly, in what manner violent events and deeds by the parents affect the psychology of children and how it inculcates aggressive behaviour in their minds has been studied. What role is played by the parents in grooming the personality of children and ultimately their decisions to choose the right or wrong way has been argued. In the light of the theory of Judith Harris, this research paper highlights all the phenomena involved: How the social hierarchy controls the behaviour. In addition, the aggressive approach of the people in their lives has been analyzed in the light of the study of second theorist Thomas W Blume. As the novel is a unique representation of supernatural characters, the monsters, which are the products of some cruel deeds, this research paper brings out different dimensions of human sufferings with respect to these supernatural beings. Moreover, the researcher also discusses that, in what manner the curse of violence creates an inevitable vicious cycle of cruel monsters that makes the life of the characters turbulent and miserable.

Hospitals are the major contributor to environmental corruption and the biggest drain onenergy in their life cycle because they are complex, multifunctional giant facilities. Several recent studieshave been carried out to find the most suitable solutions to reduce energy consumption provide it on-siteand contribute to supporting economic, environmental and social aspects. The reason for the slowmovement of green buildings for hospitals is to focus on a suitable design for the complex function thatdeals with the local climate, natural resources, economy and cultural values and avoid the one-size-fits alldesign. This made the solutions used multiple and varied, different for greening of the hospital and put theresearch in the absence of a clear perception of the mechanisms of the application of green architecture inhospitals and this identified the problem of research. Therefore, the study looked at an analytical study ofexisting project models designed according to the strategies and standards of green architecture todetermine the strategies adopted in each project, and by adopting the analytical method after determiningthe strategy used in each building to achieve the green architecture and then comparing them according tothe standards adopted using the global LEED system Green Building Council. The results that will bereached are the mechanisms of applying Green Architecture to Hospitals.
