“…The obtained results were close to the computational results, and the effects of ratio of beam stiffness to plate stiffness were revealed by their equations [3]. Virag Mikami and API methods to optimize the design of the stiffened plates with different stiffener shapes and subject different types of loadings by taking three design variables: plate thickness, dimension, and number of stiffeners [4]. Afonso and coworkers presented developments, integration and applications of reliable and efficient computational tools for structural optimization of the stiffened plates.…”

Direct resistance check by applying advanced numerical models is getting increasingly used for the design of steel slender plated structures. This method has to take into account the same uncertainties as traditional analytical design calculations and should ensure the Eurocode-based prescribed safety level. The application of the model factor gives the possibility to account for the model-related uncertainties. The current study focuses on the determination of the model factor for one specific failure mode, the patch loading resistance. Numerical model has been developed and validated based on laboratory test results. To evaluate the model uncertainties, physically possible modeling differences are introduced, and their effects are evaluated on the resistance. The final aim of the study is to determine the model factor for the analyzed girder type and failure mode based on statistical evaluation.

“…On the type level, the critical point in most works is the graph theory [6], where possible topologies are enumerated to get the best type. Various optimization techniques can be employed to solve different problems like traveling salesman [7], stiffened plates [8] or heat exchangers [9].…”

In this paper a detailed description of a method is presented to estimate the minimum structural dimensions of the robot arms. A comparative study is conducted between the harmony search and artificial bee colony algorithms in this scientific application. The comparison process was done through the kinematic equations of the serial robot manipulator to find the optimum lengths of links of the robot. A novel design for a seven-degrees-of-freedom robot arm was presented to conduct the comparative study on the presented optimization algorithms. This novel robot mimics the functionality of the SANDVIK robot arm for tunnelling works, but the presented type synthesis was designed to overcome the restrictions on the original SANDVIK arm.
