Structural Compatibility of Infrastructures Utilizing Alternative Earth Construction Materials

Reactive dye extraction utilizing regenerated bleaching earth

Bentonite bleaching earth is utilized for purifying used motor oil through a recovery process in order to improve the quality and stability of the final product. Indeed, spent bleaching earth is generated due to adsorbing oil impurities. Polluted spent bleaching earth contains 20-40% (w/w) oil and is flammable. Its disposal without pre-treatment leads to loss of oil along with environmental imp...

STRUCTURAL RELIABILITY ASSESSMENT UTILIZING FOUR METAHEURISTIC ALGORITHMS

The failure probability of the structures is one of the challenging problems in structural engineering. To obtain the reliability index introduced by Hasofer and Lind, one needs to solve a nonlinear equality constrained optimization problem. In this study, four of the most recent metaheuristic algorithms are utilized for finding the design point and the failure probability of problems with cont...

An Alternative Earth: COMMENT

Applying Verbal Decision Analysis on the Choice of Materials to the Construction Process of Earth Dams

The choice of materials to be used on the construction of earth dams is made in an empirical way, taking into account previous projects and the experience of the involved engineers. An engineer often specifies the materials and their quantities that will be used based on previous projects, on the geotechnical information about the materials available and on common sense. In order to improve thi...
