Genetic Algorithm Based Software for Optimization and Design of Piles on Slopes

Current Perspectives on Applied Geomorphology [Working Title]

Landslides in layered soil in slopes is a common phenomenon that leads to major damages to infrastructures. Piles are deep foundations which are useful structural elements to support heavy loads in difficult slopes, and to retain creeping or sliding slopes. Controlling the stability of structures made on slopes is still one of the major problems in engineering. Piles are being used successfully to support structures on slopes and have become an efficient solution for such situations which demands construction on sloping grounds, since piles can often be easily installed without disturbing the equilibrium of the layers of soil in the slope. In this paper, an optimized design approach have been adopted for design of single piles for supporting infrastructure on layered soil slopes. A standalone software has been developed as a result of this study which produces the optimum pile dimension, reinforcement details and an estimate of the design as software output. The code is written in M...

Optimization of an Inter-storey Isolated Structure Using Genetic Algorithms

The paper studies the influence of an optimal inter-storey isolation system on seismic behaviour of a concrete structure. The inter-storey isolation system uses lead rubber bearings at a certain level of the structure. The structure will be subjected to a series of pulse like earthquakes in order to account for the variability of the hazard of the Vrancea source. The article will study a concrete structure which will be modelled using finite element software. The parameters and location of the story isolation system will be studied and optimized using genetic algorithms. The optimization will be applied in order to minimise displacements. The parameters which will be optimized will be the story where isolation system is equipped and its dimensions.

Near-optimal Placement of Piles in Grillage Type Foundations Based on Simulated Annealing

Conference proceedings: 2020 IEEE Open Conference of Electrical, Electronic and Information Sciences (eStream), 2020

A problem of optimal positioning of piles in grillage type foundations is studied. A Global Optimization model reported in the literature is used to formalize this problem. A novel Simulated Annealing algorithm is developed to handle the Global Optimization problem. The algorithm employs six different optimization strategies. Computer experiments demonstrated that the proposed algorithm provides solutions with values, which are 5.8 % better than the solutions delivered by the existing state-of-the-art Genetic Algorithm and Simulated Annealing algorithm.

Optimization of a Seismically Isolated Structure Using Genetic Algorithms

In this paper, the dynamic response of an isolated structure supported by lead rubber bearings is studied. The isolated building is modeled using finite element software. Each bearing is modeled using its yield force, elastic stiffness and plastic stiffness. The main objective of the paper is to find the optimal parameters of the base isolation system using genetic algorithms in order to minimize the displacement of the building. In order to minimize the objective function an elitist non-dominated sorting genetic algorithm is employed. The study focuses on a 10 story concrete structure rehabilitated according to new design prescriptions. The optimal distribution is determined using nonlinear time history analysis and three earthquakes pertinent to the Vrancea source.
