Summary: In this study, an adaptive harmony search algorithm was used to optimize a seismic isolator placed on the base of a structure under various earthquake records. The study found that isolators with low damping ratios require more ductility, and as the damping ratio increases, further restriction of the isolator's movement increases the control efficiency.

Summary: Residual soils, due to the structure resulting from geological formation processes, behave differently from classic soils and can undergo degradation under static and cyclic loads. This study aimed to evaluate the behavior of weakly bonded residual soil under loading and unloading cycles through field plate load tests. The results showed no shape effect of the loaded area for both monotonic and cyclic loading, and a threshold load was identified that indicated a change in soil behavior.

Summary: This paper presents and evaluates a strategy for designing optimum fiber patterns of constant thickness variable-stiffness laminated composite plates and shells. The optimization framework utilizes finite element analysis and the particle swarm optimization algorithm, with a main contribution being the method proposed for parametric description of fiber orientation. Scalar values assigned to control points on the structure are taken as design variables, and these values are interpolated using radial basis functions to define the fiber orientation on the structure's surface. The proposed strategy is applicable to flat and curved structures, ensuring fiber continuity and requiring fewer design variables compared to element-wise fiber angle optimization. The effectiveness of the strategy is demonstrated through optimization of a flat plate, a shallow shell with a hole, and a pressure vessel.

Summary: In this paper, a new form-finding method based on spatial elastica model (FMSE) is proposed for elastic gridshells. The method integrates the deformations of elastic rods into the overall deformation of the gridshell, and solves a set of transcendental equations using the quasi-Newton method to ensure the deformation satisfies the given boundary conditions. The method is validated through experiments and expected to have potential applications in the investigations of elastic gridshells.

Summary: This study investigates the performance of composite pressure vessels under damaged and undamaged conditions, providing insights into their reliability and residual strength capabilities. The results demonstrate that the damage profile and its effect on compressive strength are similar between damaged and non-damaged cylinders. When subjected to quasi-static compression, the polyethylene liner absorbs enough elastic strain energy to recover without plastic deformation. Additionally, quasi-static compression has little to no influence on the axial strength of the cylinders. The damage characterization reveals fiber breakage, delamination, local buckling, and brooming failure. This study has direct implications for the safety design tolerances, manufacturing strategies, and operational failure conditions of composite overwrapped pressure vessels (COPVs).

Summary: This paper presents a study on six single-stringer specimens manufactured using the card-sliding technique with non-crimp fabrics and adopting a Double-Double (DD) stacking sequence. The specimens were tested under compression loading conditions to investigate post-buckling and failure in aerospace structures. Experimental results and numerical simulations were compared to analyze the behavior and failure modes of the specimens. The study found promising evidence of a viable solution to optimize aeronautical structures and enhance resistance to skin-stringer separation, particularly with the use of tapered flanges.
