This study tries to examine the effect of different parameters on stress analysis of infinite plates with central quasi-triangular cutout using particle swarm optimization (PSO) algorithm and also an attempt has been made to introduce general optimum parameters in order to achieve the minimum amount of stress concentration around this type of cutout on isotropic and orthotropic plates. Basis of the presented method is expansion of analytical method conducted by Lekhnitskii for circular and elliptical cutouts. Design variables in this study include fiber angle, load angle, curvature radius of the corner of the cutout, rotation angle of the cutout and at last material of the plate. Also, diagrams of convergence and duration time of the desired problem are compared with Simulated Annealing algorithm. Conducted comparison is indicative of appropriateness of this method in optimization of the plates. Finite element numerical solution is employed to examine the results of present analytical solution. Overlap of the results of the two methods confirms the validity of the presented solution. Results show that by selecting the aforementioned parameters properly, less amounts of stress can be achieved around the cutout leading to an increase in load-bearing capacity of the structure.

Solid waste management is of great concern in today's world. An enormous amount of waste is generated from various industrial activities. Concrete production utilizing some of the potential waste materials will add to the benefit of society. These benefits will include reduction of landfill burden, improved air quality, riverbed protection due to excessive sand excavation, economical concrete production and much more. This study aims to utilize waste granite powder (GP) originating from granite industries as a sand replacement in concrete. Fine GP was collected in the form of slurry from different granite cutting industries. In this study, GP was added in an interval of ten percent as 10%, 20%, 30%, 40% and 50% by weight of sand in concrete. Mechanical assets; compressive strength, flexural strength and splitting tensile strength were prominent for control and blended mixes. Modulus of elasticity (MoE) and abrasion tests were also performed on control and blended specimens of concrete. To provide a comprehensive clarification for enhanced performance of GP prepared concrete samples, scanning electron microscopy (SEM) and X-ray diffraction (XRD) were performed. Results indicate that 30% replacement of sand by weight with GP enhances the mechanical assets of concrete and even the results obtained for 50% replacement are also acceptable. Comprehensive analysis through SEM and XRD for 30% replacement was better than control one. The performance of GP added to concrete in terms of abrasion and modulus of elasticity was far better than the control mix. A significant outcome shows the appropriateness of granite fines to produce sustainable and environmentally friendly concrete.

In this study, the concept of environmental-friendly architecture, where environment is importantly regarded as a design concept in modern architecture and the meaning of boundary are examined, To apply properly design methodologies along with the importance of environment, the concept of environmental-friendly architecture should be first correctly established. And as the recent rapid development of technologies provides new possibilities for environmentally-friendly architecture, it is needed to have a new boundary concept and the interpretation of the meaning of boundary differentiated from the one of existing architecture. Recently the meaning of boundary is expanding its range to the relations with its neighboring environment beyond the relations with in and out of a space and has also the role as a medium for exchange and communication instead of breaking-off. Therefore, the boundary of environmental-friendly architecture alongside physical boundary is extended to the area for communication. Here, a basic boundary of architecture is maintained, but its meaning and expressions get natural shapes. The study deals with the analysis of the concept of environmental-friendly architecture and its changes from the perspective of times, environment and social backgrounds and seeks its appropriateness centered on environmental-friendly architecture Since 1980s when the issues of human and environment were raised in earnest.
